In the field of cryogenic containers, liquid nitrogen tanks play a very important role. With the continuous advancement of science and technology, the functions of liquid nitrogen tanks have become more comprehensive. There are two storage modes: gas-phase liquid nitrogen tanks and liquid-phase liquid nitrogen tanks. However, their working principles and usage methods are slightly different.
Among them, gas-phase liquid nitrogen tanks have the advantages of preventing sample cross-infection, reducing the risk of sample tube explosion, and reducing liquid nitrogen damage. Therefore, most laboratories and scientific research institutions currently prefer to use gas-phase liquid nitrogen tanks for sample storage.
Its working principle is also very simple, which is to store liquid nitrogen in a tank and use the evaporation and cooling of the liquid nitrogen to preserve the sample. At the same time, it also has high vacuum insulation technology to reduce the volatilization rate of liquid nitrogen and keep the pressure inside the tank stable.
In addition, there is a tray inside the gas phase tank. The liquid nitrogen is stored below the tray, and the sample storage space is above. This design makes good use of space.
The structure of the liquid-phase liquid nitrogen tank is different. It puts the sample directly into the liquid nitrogen so that the sample is completely submerged. The advantage of this method is that the temperature is lower and the sample can be stored for a longer period of time.
However, today's science and technology are so advanced that liquid nitrogen tanks have been used in both gas and liquid phases. For example, KGSQ's gas-phase liquid nitrogen tanks and small gas-liquid phase tanks are compatible with both gas-phase and liquid-phase storage modes, allowing you to use them at any time Switch to meet different experimental needs.
In any case, both gas phase tanks and liquid phase tanks have their own advantages. The stable structure and performance of the gas phase tank can ensure the long-term storage of liquid nitrogen and can also reduce problems such as leakage and volatilization of liquid nitrogen. The liquid phase tank has the advantages of lower temperature and easy operation, which are also popular among users.

For laboratories, the cell samples stored in liquid nitrogen tanks are relatively precious. If liquid nitrogen is not added in time, the cell samples will lose their activity due to insufficient liquid nitrogen, causing unnecessary losses. To avoid this kind of situation, we can choose a liquid nitrogen tank alarm to help us check how much liquid nitrogen is left in the tank, and remind us to replenish it in time when the liquid nitrogen is insufficient.
What is a liquid nitrogen tank alarm?
The liquid nitrogen tank alarm is specially developed and produced for measuring the liquid nitrogen balance and temperature in the liquid nitrogen tank. It uses imported high-precision sensor probes and is powered by dual 18650 large-capacity batteries. The USB port can be connected to an external power supply for power supply and charging. It has an ultra-low power consumption design. A single battery can last for 4 months (real-time data is reported once every 10 minutes). With accurate measurement and excellent performance, it is widely used in liquid nitrogen cryogenic equipment, pharmaceutical warehouses, cold chain transportation, laboratories and other places.
working principle:
It uses imported high-precision sensor probes to measure the temperature of liquid nitrogen and output information to the terminal;
Liquid nitrogen tank alarm features:
1. Imported high-precision probe, with high measurement accuracy, large range and good consistency.
2. With a cloud monitoring platform, there is no need to monitor hosts, collectors and other equipment.
3. Easy to use, you can use the mobile APP or log in to the web page to view the data.

8. Desktop wall-mounted magnetic structure design, easy to install; has super stability and anti-interference ability.
Livestock liquid nitrogen tank, as a low-temperature container, is usually used to store animal semen. During storage, liquid nitrogen is used as the refrigeration medium. However, the temperature of liquid nitrogen is -196C, and its volatile nature is its constant attribute. Therefore, when the staff opens the liquid nitrogen tank to take out the frozen semen, the contact heat increases as the residence time increases. The sample placed in the bucket will be exposed to part of the normal temperature after being taken out, and the temperature will gradually rise. If it is placed in the liquid nitrogen tank again, the volatilization of liquid nitrogen will also be accelerated.
However, the loss of frozen semen is normal. Frequent users know that we only need to replenish liquid nitrogen in time to ensure the safety of frozen semen in livestock liquid nitrogen tanks.
When it comes to rehydration, there are many ways to replenish liquid nitrogen, including pouring it directly yourself, or using tools such as liquid nitrogen pumps and liquid nitrogen supply tanks. Among them, liquid nitrogen pump is a common and practical "liquid replenishment artifact". It is divided into two types: foot pump and automatic pump; their pump bodies are made of stainless steel, which are easy to operate, beautiful and durable.
How to use liquid nitrogen pump:
1. Close the liquid nitrogen pumpâ??s liquid outlet valve;
2. Insert the liquid inlet of the liquid nitrogen pump into the neck of the jar and turn it clockwise until it is tight;
3. Also insert the liquid nitrogen pump outlet into the tank, and seal the liquid nitrogen pump and neck tube with a sealing ring;
4. If it is a foot pump, you can control the liquid discharge by simply stepping on it; if it is an electric pump, you can control the discharge of liquid nitrogen through the mobile phone APP.
Generally speaking, the foot pump has a liquid output of about 5L per minute, and the mechanical pump has a liquid output of about 8L per minute.
Note: Whether it is a foot-operated or mechanical liquid nitrogen pump, the diameter of the tank is required to be 50mm and the volume is greater than or equal to 10L. Liquid nitrogen tanks that do not meet the conditions cannot be used.
As we all know, a soldier with a very handy weapon can exert greater combat effectiveness in battle. This sentence tells us that no matter what position you are in, a handy "weapon" can make you more handy in the work process and get twice the result with half the effort.
In our scientific research institutes and laboratories, we cannot do without a handy "weapon", and this "weapon", in my opinion, is a laboratory liquid nitrogen tank.
Why I say this is because in the laboratory, experimental samples are particularly important. They generally need to be stored at low temperature. Its safety directly affects the accuracy of experimental results. Laboratory liquid nitrogen tanks provide a safe and stable low-temperature storage environment for experimental samples.
Of course, laboratory liquid nitrogen tanks do not only have this feature, they also have:
1. Large capacity storage space
In scientific research institutes and laboratories, there will be a situation in which experimental samples are stored in large quantities and types, and most of them need to be stored for a long time. At this time, small-capacity jars are used, which not only has limited storage space and cannot be stored in categories, but also requires frequent refills. Therefore, the liquid nitrogen tanks usually used in laboratories are above 30 liters.
2. Large diameter + square bucket
In order to facilitate the staff to find and manage samples, and because the number of samples is relatively large, laboratory liquid nitrogen tanks are usually used as formula buckets, which can store cell samples in separate compartments, in large and regular quantities, and can also be stored in categories. Due to the size limit of the square pail, laboratory liquid nitrogen tanks are all large-diameter, above 125mm, and the commonly used diameters are 125, 127, 210, and 216mm.
3.Safety lock cover
Experimental samples are crucial to every worker doing experiments. Therefore, the safety of the samples cannot be ignored. In order to ensure the safety of the samples and prevent them from being accidentally taken or lost, in addition to square buckets and protective covers, usually A lock cover will be added and a lock will be installed to ensure safety.
With so many features, the laboratory liquid nitrogen tank is not a useful "weapon" for the laboratory.

In scientific research institutions or pharmaceutical companies, some biological samples need to be stored in liquid nitrogen sample storage tanks.
Liquid nitrogen sample storage tanks are an important cryogenic storage equipment that many people are not familiar with. So as a manufacturer of KGSQ liquid nitrogen tank, let me briefly introduce how to use it.
1. Before use, you need to carefully check the appearance to see if there is any dent or damage, and whether the vacuum exhaust port is intact. These inspections are to ensure that the thermal insulation performance of the liquid nitrogen tank is good.
2. Liquid nitrogen tanks rely on liquid nitrogen to ensure deep and low-temperature storage, so the tanks can only be filled with liquid nitrogen. Mixing other flammable substances can easily cause interaction and cause an explosion.
3. The liquid nitrogen tank container should be placed in a cool, dry place to ensure good indoor ventilation.
4. The temperature of liquid nitrogen is -196�°C. Self-protection measures should be taken when extracting and storing the freezing rack, such as wearing leather or cotton gloves. Be cautious when operating with bare hands. At the same time, it is necessary to prevent liquid nitrogen from splashing, which may cause frostbite when it touches the skin and other parts.
5. When filling liquid nitrogen for the first time, because the vacuum liner is at normal temperature, it is not advisable to fill it too fast. A small amount should be injected first to gradually reduce the temperature of the liner. Injecting a large amount of liquid nitrogen can easily cause the liquid nitrogen to boil. At this time, slow down. Wait for the liquid nitrogen to cool down slightly before injecting liquid nitrogen faster. Otherwise, the liquid nitrogen will boil and splash outward, causing frostbite.
6. Liquid nitrogen should not be overfilled, and the liquid level should not be in contact with the fiberglass neck tube.
7. Liquid level height check: Insert a wooden ruler vertically into the center bottom of the liquid nitrogen tank and take it out after about 15 seconds. The frost length is the liquid level height. Never use a hollow tube for inspection to prevent liquid nitrogen from erupting from the tube and injuring people.
8. Make sure that the liquid nitrogen submerges the refrigerated items. When the liquid nitrogen is consumed to the point where the refrigerated items are about to be exposed to the liquid surface, liquid nitrogen should be replenished in time.
If you have any needs, please contact KGSQ liquid nitrogen tank:
In breeding farms, animal reproduction is inseparable from frozen semen. A certain amount of frozen semen is stored in every farmer's home. These frozen semen like to live in low-temperature environments. Once exposed to normal temperature, they may become inactive and lose the ability to reproduce. Therefore, the preservation of frozen semen cannot be careless! For this reason, farmers will choose liquid nitrogen frozen semen tanks as containers for storing frozen semen because it has the advantages of heat preservation and insulation. With the help of liquid nitrogen, it can keep the interior in a stable low-temperature environment and at the same time isolate the outside heat from entering.
However, there are bugs in using liquid nitrogen to preserve frozen semen. It is volatile and requires constant attention to the amount of liquid nitrogen in the tank. If the margin is insufficient, the safety of frozen semen will be threatened. Therefore, when the remaining liquid nitrogen cannot cover the frozen semen, it needs to be replenished in time.
So the question is, how long can a liquid nitrogen tank store liquid nitrogen? When should I replenish liquid nitrogen?
It depends on when the liquid nitrogen will be used up!
Under the premise of consistent capacity, caliber plays a decisive role!
According to the rules of the liquid nitrogen biological container industry, the larger the diameter, the shorter the storage time, and the opposite is true for small diameters.
Letâ??s take a 30-liter liquid nitrogen tank as an example.
50mm small diameter, liquid nitrogen static storage time is 260 days;
80mm small diameter, liquid nitrogen static storage period of 150 days;
125mm large diameter, static storage in liquid nitrogen for 90 days;
210mm large diameter, static storage in liquid nitrogen for 49 days!
Therefore, when the liquid nitrogen frozen sperm tank is 30 liters and 125mm, liquid nitrogen needs to be replenished every 90 days; if it is 30 liters and 210mm, liquid nitrogen needs to be replenished every 40 days!
In addition, please note that static storage time â? usage time!
Static storage refers to the state of being filled with liquid nitrogen and not being opened or used. This is only the reference data provided by the manufacturer to the user. As for the dynamic consumption of liquid nitrogen, each userâ??s opening frequency and the dwell time each time the lid is opened are different, so it is impossible to Calculate accurately and provide reference.
The safe way is to fill up the liquid nitrogen once, use it once and record it to determine your own dynamic storage time.
Also, donâ??t forget to ensure that the liquid nitrogen always covers the frozen sperm, so that the spermâ??s vitality is guaranteed!

Widely used, complete models and accessories: livestock frozen sperm storage liquid nitrogen tanks are divided into 2L, 3L, 6L, 10L, 16L, 30L, 35L and 47L. 16L frozen sperm storage tanks are a popular frozen sperm storage tanks for livestock users; wide base design, stable chassis, not easy to shake and tilt, not only large capacity but also can be used with a large amount of liquid nitrogen, and can be used with a large amount of liquid nitrogen, and can be used with a large amount of liquid nitrogen.
In the fields of biological sample repository, medical cold storage, animal frozen sperm, vaccine storage and scientific research experiments, the sealing performance of liquid nitrogen tanks is the core to ensure temperature stability and safe storage of samples. Long-term cryopreservation is achieved through a unique vacuum insulation design, the key technologies of which include double chamber design, neck tube design and insulation material filling. Today, we will discuss in depth the hermeticity of liquid nitrogen tanks and how it ensures that the internal liquid nitrogen is isolated from the external environment and maintains its ultra-low temperature status.
1. Vacuuming inside and outside the tank
The liquid nitrogen tank has a double-layer design of inner and outer gallbladder, with the inner gallbladder storing liquid nitrogen, and the vacuum sandwich between the outer gallbladder and the inner gallbladder effectively blocking heat conduction, which significantly improves the heat preservation performance and airtightness.
2. Adiabatic material wrapping to maintain low internal temperature
Multiple layers of insulating materials are filled to provide additional insulation and sealing protection for the inner liner, reducing the influence of the external environment on the liquid nitrogen inside the tank and improving the safety of sample storage.
3. Insulated neck plugs to isolate heat and guard the safety defense.
Do a good job of sealing between the two chambers, insulating and filling between the two chambers, and the important tank opening.
Currently, the technology of using liquid nitrogen to freeze animal semen for artificial insemination has been widely used in livestock production.
Because the temperature of liquid nitrogen is -196�°C, and its boiling point is low, it is easy to volatilize and is difficult to store. Non-special containers - liquid nitrogen tanks cannot be stored well, let alone serve as a refrigerant for freezing semen. Therefore, it is difficult to use Liquid nitrogen containers for storing semen have become one of the essential equipment in animal husbandry.
In animal husbandry applications, in addition to preserving animal semen as mentioned above, liquid nitrogen tanks are also mainly used for freezing embryos, preserving veterinary drugs, vaccines, etc. Of course, the main focus is on the preservation and transportation of sperm from male animals such as pigs and cattle.
At this point, I have to mention that as a low-temperature container for storing animal semen, the capacity selection of livestock liquid nitrogen tanks cannot be ignored. Appropriate capacity can help breeders effectively and quickly preserve animal semen.
So how to choose?
Look at the specific usage scenario!
If you go out to collect semen, the quantity is generally not very large, but when you go into mountainous areas, you often use portable small-diameter liquid nitrogen tanks, mostly with a capacity of 6 liters and 10 liters. Although there are also smaller ones of 3 liters, they are static liquids. The storage time of nitrogen is short, and under such dynamic conditions, liquid nitrogen will evaporate faster, so its use is not recommended;
There is also a 16-liter capacity option, which is a small vehicle-mounted tank with better stability and longer storage time of liquid nitrogen.
For long-term storage of frozen semen, you can choose a 30-liter or 35-liter liquid nitrogen tank with a diameter of 125mm. It has a static storage time of about 3 months. It is very suitable for long-term storage at home. Frequent replenishment of liquid nitrogen is not required. The quantity is between 5,000-20,000, which can meet the needs of most frozen semen users.
To sum up, you can choose 6 liters, 10 liters, or 16 liters of liquid nitrogen tanks with a diameter of 50m for out-of-town semen collection; you can choose 30, 35 liters, and 125mm diameter tanks for long-term storage. Of course, the quantity of frozen semen cannot be ignored!
If you have any needs, please contact KGSQ liquid nitrogen tank:
Liquid nitrogen tanks, according to the classification of liquid nitrogen status, can be divided into liquid-phase liquid nitrogen tanks and gas-phase liquid nitrogen tanks;
Biological samples in liquid-phase liquid nitrogen tanks are stored under the surface of liquid nitrogen, and the samples are immersed in liquid nitrogen.
Biological samples in gas-phase liquid nitrogen tanks are stored in a nitrogen atmosphere in the liquid nitrogen temperature zone without direct immersion.
The gas-phase liquid nitrogen tank is made of stainless steel, which has the advantages of corrosion resistance, low temperature resistance, high strength, and high load-bearing. It uses high vacuum insulation technology to reduce the evaporation rate of liquid nitrogen and maintain stable pressure in the tank.
The characteristics of gas phase liquid nitrogen tanks are:
1. Designed for gas-phase storage of samples. Gas-phase storage does not require direct soaking in liquid nitrogen, which can avoid the risk of cross-infection between samples.
2. The neck temperature can reach -190�°C. This diameter design, coupled with vacuum technology, reduces the evaporation loss rate of liquid nitrogen and lowers operating costs.
3. Convenient access, 2-level steps and partitioned tray rotation design, superheated gas is automatically eliminated during fluid replenishment.
4. Equipped with an intelligent monitoring system to monitor liquid level, temperature, and remaining liquid nitrogen capacity in real time. It can be connected to the monitoring terminal to achieve centralized data management. It can actively alarm in 19 states and can send alarm information to mobile phones to ensure the safety of liquid nitrogen tanks and samples in an all-round way.
5. Has one-click defog function.
6. The structure has an earthquake-resistant design to prevent damage to the tank caused by earthquakes.
The large capacity of the gas-phase liquid nitrogen tank determines its advantage in long-term storage of large batches of biological samples. The combination of modern technology and stainless steel storage tanks makes it easy and convenient to store large batches of samples.
Laboratory liquid nitrogen tanks are generally used to store important samples such as biological cells and vaccines. In some special cases, the tank needs to be transported short distances. Laboratory liquid nitrogen tanks are usually large in capacity and volume. It is very difficult to move them. It requires at least two people to lift and move them. It is time-consuming and labor-intensive and larger in size. Even two people couldn't lift it.
So how to solve the problem of short-distance movement of laboratory liquid nitrogen tanks?
It can be moved with the help of tools - liquid nitrogen tank trolley.
The liquid nitrogen tank cart is a relatively common means of transporting liquid nitrogen tanks. It is made of stainless steel, has strong load-bearing capacity, beautiful appearance and is easy to clean. It has universal wheels at the bottom, which saves effort in pushing and pulling, and allows flexible movement. The wheels are wear-resistant. Comes with built-in brake, easy to operate.
How to use the liquid nitrogen tank cart:
1. Install the cart;
2. Place the liquid nitrogen tank into the base of the pallet truck and secure it;
3. After being fixed, the transport vehicle can be moved flexibly indoors by pushing it;
4. Turn on the brake after moving to the designated location to avoid rolling away and causing unnecessary losses.
In short, the emergence of liquid nitrogen tank carts is to assist staff in moving liquid nitrogen tanks more conveniently and using them safer.

At present, livestock breeding has become an important pillar industry in rural areas. In recent years, with the continuous development and progress of animal husbandry, frozen semen technology has become more and more mature, and artificial insemination and breeding have become the main ways to improve livestock species. This technology can keep semen active for a long time, helping to improve the production capacity and breeding effect of animals during the breeding period. Therefore, it is widely used in the livestock industry.
In the application of this technology, a container - livestock liquid nitrogen tank - is indispensable in this case.
It is made of high-strength aviation aluminum and is designed for breeding users to carry easily when going out. It is a livestock liquid nitrogen tank specially designed for them. The inner and outer double bladders are multi-layered and insulated, small in size, light and easy to carry, and can reduce the evaporation rate of liquid nitrogen to a great extent. When used for cryopreservation of cattle semen and cell vaccines, it can ensure safe and efficient storage, which is both economical and practical, especially Suitable for animal sperm sampling and breeding work in remote areas.
Livestock liquid nitrogen tanks have many advantages, but when using them, you also need to pay attention to the following operating matters to improve work efficiency and reduce operational risks.
1.Regular rehydration
When the liquid nitrogen balance inside the livestock liquid nitrogen tank cannot cover the biological samples, liquid nitrogen needs to be added to maintain the low-temperature freezing environment in the tank;
2. Quick access
When accessing the frozen semen tube, the time should not exceed 10 seconds. If it is not taken out within the time limit, the bucket needs to be soaked in liquid nitrogen again, and then taken out again after a while;
3. Bucket position
When taking out the frozen sperm tube, do not take the bucket outside the liquid nitrogen tank. The bucket should be lower than the mouth of the tank. Use tweezers to pick up the frozen sperm tube after it is exposed;
4. Check the tank
During the use of livestock liquid nitrogen tanks, you should check the tank at any time. If any abnormalities are found, such as a dent in the tank, pay attention to the loss of liquid nitrogen. If the loss suddenly increases, the cow essence should be transferred immediately and contact the manufacturer to check the vacuum degree of the tank. If If the vacuum degree is abnormal, it needs to be returned to the factory for repair or replacement. Transfer frozen semen;
If you have any needs, please contact KGSQ liquid nitrogen tank:

When not in use for a long time, it should be cleaned and stored to prevent sample residue from corroding the tank wall and affecting the service life;
It is recommended to place it in a well-ventilated area and regularly check the insulation performance of the tank;
In short, the role of liquid nitrogen tanks in the laboratory is irreplaceable, but their correct use is crucial. During the operation, you must not only pay attention to the storage of the liquid nitrogen tank, but also the addition and correct use of liquid nitrogen to ensure the safety of staff and samples.
The self-pressurizing liquid nitrogen tank is an efficient and safe liquid nitrogen storage equipment, which is widely used in life sciences, medical research and other fields. So, what exactly is it?
First, we need to understand how a self-pressurizing liquid nitrogen tank works. It vaporizes a small amount of liquid nitrogen in the tank, causing the internal pressure of the entire container to increase. When the pressure inside the container reaches the critical pressure, the drain valve needs to be opened to realize the continuous drain function. It is specially used to replenish liquid nitrogen in laboratory cryogenic containers to ensure the smooth progress of experiments.
Secondly, the safety of self-pressurizing liquid nitrogen tanks is also very high. It is equipped with double safety automatic control valves, which have double safety measures and are safer to use. It ensures that the liquid nitrogen tank pressure does not exceed the limit, thus avoiding the risk of accidental leakage and explosion.
In addition, self-pressurizing liquid nitrogen tanks also have certain sealing properties. Although it looks like a tightly sealed jar from the outside! But it has a vent, a pipe for nitrogen to be discharged. When it is filled with liquid nitrogen, we only need to open the drain valve of the tank, and the nitrogen evaporated by the liquid nitrogen will be discharged to the outside from the drain port. There is no pressure inside the tank.
Finally, self-pressurizing liquid nitrogen tanks are easy to operate. It has only 4 valve controls, and users can realize the functions of pressurizing, depressurizing and releasing liquid nitrogen with simple operations.
In short, the self-pressurizing liquid nitrogen tank is a highly functional, safe and efficient liquid nitrogen storage device that is widely used in scientific research, medical and agricultural fields.
The use of liquid nitrogen has become increasingly common in scientific experiments and medical fields. As an ultra-low temperature liquid, it requires special containers, namely liquid nitrogen tanks, for storage and transportation.
Liquid nitrogen tanks are a series of low-temperature containers that are made of aviation aluminum and have double-vacuum structures. They can only be used for liquid nitrogen storage or transportation. The advantage is that they are well insulated and can store liquid nitrogen for a long time, so that liquid nitrogen can be used to freeze biological samples. The disadvantage of using it is that it is difficult to move after loading liquid nitrogen and samples, and it is afraid of bumps. The connection between the neck tube and the inner tank cannot withstand shaking.
However, in the storage of experimental samples, it is difficult not to involve the issue of indoor transportation. After all, it must serve the experimental subject.
then what should we do?
Under this demand, the liquid nitrogen tank trolley came into being!
It is a tool specially designed for transporting liquid nitrogen containers. It has become an indispensable helper in the laboratory with its advantages of durability, wear resistance, collision resistance and ease of movement.
The liquid nitrogen tank trolley is made of 304 stainless steel. The mechanical properties of the steel enable the trolley to maintain core stability when transporting liquid nitrogen containers and not deform due to constant pressure. For some emergencies, such as collision and friction, the wear resistance and collision resistance of stainless steel can effectively reduce the impact on the container and ensure safe transportation.
In addition, the trolley is equipped with universal wheels. This user-friendly design makes movement more convenient and allows users to easily transport liquid nitrogen containers from one place to another. This is undoubtedly a great boon for laboratories and medical institutions that need to frequently move liquid nitrogen containers. The emergence of liquid nitrogen tank trolleys has effectively improved transportation efficiency and reduced labor costs.
In short, liquid nitrogen tank trolleys have become an essential tool for transporting liquid nitrogen containers due to their durability, wear resistance, collision resistance, and convenience and ease of movement.
Liquid nitrogen, as a low-temperature liquid of -196 , cannot be stored in any container. It requires a special container, a liquid nitrogen tank, for storage.
Containers for storing liquid nitrogen can be divided into two types: one is an open liquid nitrogen tank, which can store liquid nitrogen and samples; the other is a self-pressurizing liquid nitrogen tank, which is specially used for rehydration of liquid nitrogen containers. Both have the same characteristics, including double-layer structure of inner and outer bladders; vacuum insulation; long-term storage of liquid nitrogen, etc. But apart from that, the difference between the two is still very big, letâ??s look down.
1. Different materials
The self-pressurizing tank is made of 304 stainless steel, which has good load-bearing and high strength, and has a smooth metal appearance;
The open-top liquid nitrogen tank is made of aluminum alloy, is light in weight and easy to carry. The appearance is spray-painted and is white.
2. Different functions
The self-pressurizing tank is used for the storage and transportation of liquid nitrogen. It can increase the pressure through internal liquid nitrogen vaporization and promote liquid drainage and replenishment. It cannot store biological samples;
Open liquid nitrogen tank is also called liquid nitrogen biological container. That is: a container for storing liquid nitrogen and biological samples. Samples such as frozen cell semen can be stored in it, and the deep low temperature of liquid nitrogen can be used for long-term preservation.
3. Different structures
The self-pressurizing tank as a whole consists of the tank body, valves, pipes, liquid level gauge and internal boosting plate;
The open liquid nitrogen tank is composed of inner and outer tanks, vacuum interlayer, neck tube, neck plug and bucket.
4. Different capacities
The volume range of self-pressurizing tanks is large, ranging from 15-500L;
The volume of open liquid nitrogen tanks is small, ranging from 2-175L.
In short, if you need to store biological samples, you can choose a conventional tank; if you refill other liquid nitrogen containers, you need to use a self-pressurizing tank.
In biological laboratories,the commonly used low-temperature storage equipment is liquid nitrogen tank,which can be divided into two categories according to the storage mode,one is liquid-phase liquid nitrogen tank, and the other is gas-phase liquid nitrogen tank;however, with the development of science and technology With continuous development,a small gas-liquid phase tank is now designed.To put it simply,it is a combination that draws on the advantages of both.
This description is not empty talk,letâ??s take a look below:
First of all,it uses the same aviation aluminum as the liquid phase tank as the material,which is high in strength,corrosion-resistant,and relatively lightweight,making it easy to transfer samples.
Secondly,judging from its appearance,it not only has a similar appearance to the liquid tank,but also has the same smart display as the gas tank.
Its internal structure is similar to that of a gas phase tank and is divided into a liquid nitrogen storage area and a sample storage area.
Similarly,there are two storage modes for samples.You can choose the more commonly used liquid phase storage mode,or you can choose the gas phase storage mode like the gas phase tank,which uses volatile nitrogen to preserve the sample.The dual-mode storage mode is also its name.The origin of.
The important thing is that small gas-liquid phase tanks have commonly used capacities, such as YDS-65-216,YDS-95-216.This capacity is suitable for users who do not have a particularly large number of cell samples but want to store them in gas phase.Particularly friendly and makes up for the need for small cell storage.Choosing it not only requires less investment than a gas phase tank,but also saves space and can better meet your needs.

The liquid nitrogen tank is a low-temperature container that can only store liquid nitrogen and cannot store other liquids. It is mainly composed of inner and outer gallbladders, neck tubes, neck plugs, and buckets. They play different functions in different positions. So what functions does our liquid nitrogen tank neck plug have? What will happen if we accidentally forget to cover the neck plug during operation?
You should know that the neck plug is made of polyurethane foam and is used to block the neck of the liquid nitrogen container to reduce the evaporation of liquid nitrogen and play a role in preserving liquid nitrogen. It is light and pressure-free, not easy to break, does not fall off, and can also fix the bucket without adsorbing liquid nitrogen.
If you forget to cover the neck plug during use,there will be three situations,the third situation is dangerous.
1. Liquid nitrogen volatilizes in large quantities
Liquid nitrogen is a low-temperature liquid that is easily volatile at -196�°C.It will evaporate more quickly when exposed to heat. The liquid nitrogen tank is designed to better isolate heat,so that liquid nitrogen can be stored for a long time.The neck plug is made of polyurethane foam, which is not easy to break and has good thermal insulation properties and can isolate most of the heat.
If you forget to cover the neck plug,hot air will enter through the mouth of the tank and accelerate the evaporation of liquid nitrogen.If there are samples stored in the tank,the safety of the samples will be affected and the samples may become inactive.
Therefore,when we find that we have forgotten to cover the neck plug,we must first measure the height of the liquid nitrogen in the tank,refill it,and then cover the neck plug.
2. Liquid nitrogen will be contaminated
Another function of the neck plug is to prevent impurities or bacteria from falling into the tank. If you forget to cover the neck plug, bacteria and impurities will inevitably fall into the liquid nitrogen tank and contaminate the liquid nitrogen and stored biological samples.
3. Decreased indoor oxygen content
Usually, liquid nitrogen tanks are placed indoors. Liquid nitrogen will volatilize more quickly when heated. If the room is not well ventilated, the nitrogen content in the air will increase and the oxygen content will decrease, which may cause the risk of "suffocation". Therefore, Liquid nitrogen tanks stored indoors must be well ventilated.

The liquid nitrogen level alarm is a monitoring instrument used to sense temperature changes and liquid level heights in various low-temperature liquid nitrogen containers. When the liquid level in the liquid nitrogen tank drops to a certain level, the alarm device will be automatically triggered to avoid danger during production or use.
The liquid nitrogen level alarm is so excellent, but what specific functions does it have?
Features:
1. Temperature display: can detect and display the temperature of the liquid nitrogen container in real time.
2. Fault alarm function: When the sensor is disconnected or the input is open or short-circuited, the instrument automatically emits an audible and visual alarm, the alarm indicator light on the panel lights up, and the buzzer responds.
3. Over-temperature alarm function: When the temperature of the measuring point of the liquid nitrogen container is lower than the low temperature set value or higher than the high temperature set value, the instrument automatically issues an audible and visual alarm.
4. Parameter setting function: directly set the high temperature set value, low temperature set value, control temperature value and control hysteresis value through the setting keys on the panel.
5. Silencing function:
When the instrument is in the sound alarm state, if necessary, you can click the "Alarm" button to stop the buzzer and eliminate the sound, and click it again to turn on the sound. In the setting state, click the "Alarm" button to save the setting value.
6.Power soft switch:
Long press the "Power" button on the panel to turn off the instrument power, and long press the "Power" button again to turn on the instrument power.
In addition, the liquid nitrogen level alarm can also automatically start and stop the solenoid valve according to the set temperature point to realize the liquid nitrogen replenishment function of cryogenic equipment, effectively improving the safety and reliability of the operation of the liquid nitrogen container.

Currently, the methods of cell preservation are refrigerator and liquid nitrogen. When it comes to long-term storage, liquid nitrogen wins.
However, conventional liquid nitrogen tanks need to constantly detect the liquid level, and the cells cannot be stored higher than the liquid nitrogen level, which is not conducive to long-term storage of cells.
However, the "stem cell liquid nitrogen tank" that breaks the rules can do it! For long-term storage of large quantities of dry cell samples, it is ideal to use stem cell liquid nitrogen tanks by default. Why?
1. Storage temperature is -150~-196â??
For cells, the more comfortable storage temperature is -150â??~-196â??. Conventional liquid nitrogen tanks only have a temperature option of -196â??. Samples at this temperature are not in danger.
The storage temperature of stem cell liquid nitrogen tanks changes with the sample area. The temperature difference in each storage area is 10�°C, which provides more options for cells. You can choose a more suitable temperature for cells to store.
2. Prevent pollution
Another important point in cell cryopreservation, stable storage time and how to prevent contamination during storage.
To stabilize the storage time, the stem cell liquid nitrogen tank adopts the characteristics of vacuum multi-layer insulation, electronic temperature control and liquid nitrogen dispersion, making the storage tank intelligent cooling and constant temperature process uniform and stable.
To prevent storage contamination, you must know that cells become contaminated because they are in direct contact with liquid nitrogen.
First, because the cryopreservation tube is not well sealed, liquid nitrogen enters through the gap. After taking out the test tube, there is a temperature difference and pressure difference between the inside and outside. Under the combined action of temperature and pressure, the tube explodes.
Second, bacteria will enter the liquid nitrogen tank after it has been used for a period of time. These bacteria are likely to flow into the freezing tube with the liquid nitrogen and contaminate the sample.
Stem cell liquid nitrogen tanks can prevent contamination because they can store liquid nitrogen and cells separately, avoiding direct contact between the two. At the same time, they can also use the low-temperature environment formed by the evaporation of liquid nitrogen for storage to avoid pipe explosions and cross-contamination. risk.
Spring is warm and flowers are blooming, all things are recovering, and at this time, it is time for animals to breed again. In the animal husbandry industry, preparations for animal reproduction have begun. Among them, "semen" is inseparable, which requires not only quality assurance, but also quantity. Under such demanding conditions, the preservation of semen becomes the focus.
As we all know, semen preservation is to store it in an ultra-low temperature environment after special treatment to achieve long-term preservation. Usually stored in liquid nitrogen at -196�°C. The advantage is that it can be stored for a long time and its use is not limited by time, region and animal life span.
At the same time, as a container that accompanies the demand for liquid nitrogen storage, the livestock liquid nitrogen tank can provide a vacuum insulated environment for the liquid nitrogen medium, extend its use time, and thereby preserve frozen semen. It has gained countless popularity because of its small size and light weight. User approval.
However, for the safety of frozen semen, you should pay attention to the following points when using livestock liquid nitrogen tanks:
1. When storing and withdrawing frozen semen, the lifting tube is only allowed to be lifted below the mouth of the tank, and the time out of liquid nitrogen shall not exceed 10 seconds. If necessary, it must be immersed again before extraction;
2. When transferring frozen semen, the lifting tube should not be separated from the liquid nitrogen for more than 5 seconds;
3. After storing frozen semen, the tank plug should be capped in time to reduce the number and time of opening the cap plug to reduce liquid nitrogen consumption and prevent foreign matter from falling into the tank;
4. Frozen semen of different varieties should be numbered clearly to avoid confusion.
5. Liquid nitrogen tanks used for long-term storage of frozen semen should be cleaned and scrubbed regularly to avoid collisions. If the liquid nitrogen consumption in the tank increases significantly, or if there is frost on the outside of the tank, it should be replaced in time and repaired and replaced.
Nowadays, with the continuous development of science and technology, products are constantly updated and iterated to serve us better. In the animal husbandry industry, frozen semen storage tanks are used to store frozen semen. For this purpose, many accessories are designed to assist use, including buckets, freezing racks, neck plugs, locking lids, and liquid nitrogen tank trolleys. .
Today I will focus on the characteristics of this liquid nitrogen tank cart.
The liquid nitrogen tank trolley is a tool for convenient transportation of liquid nitrogen tanks. Also often referred to as a "liquid nitrogen tank trolley". It helps users to transfer the jars to anywhere easily without much force. In addition to being very popular in the animal husbandry industry, this kind of trolley can also be used in laboratories, hospitals and other occasions where large liquid nitrogen containers are required, which can greatly improve work efficiency.
There are three characteristics:
1. Innovative design, safe and reliable. The liquid nitrogen tank trolley is made of all stainless steel, ensuring its durability and corrosion resistance. Making the transfer process more stable and reliable!
2. Save physical energy, worry and effort. By using the liquid nitrogen tank trolley, staff no longer have to spend a lot of energy to carry liquid nitrogen tanks! Simply place the container on the cart and transporting the liquid nitrogen tank is a breeze!
3. Can be customized and flexibly chosen. This stroller not only has a stylish and beautiful appearance, but you can also tailor-make your own stroller according to your own needs.

As we all know, liquid nitrogen tanks are used to store liquid nitrogen and preserve biological samples. They can maximize the low-temperature characteristics of liquid nitrogen. It is used in different industries such as medical research and industrial cold assembly. Small gas phase liquid nitrogen tanks, although also called liquid nitrogen tanks, are very different from traditional liquid nitrogen tanks.
Then letâ??s start talking about where they differ.
Small gas-liquid phase tank, it is a new type of liquid nitrogen biological container between the YDS series and YDD series. It has the same aviation aluminum material as YDS. The inner and outer tanks are made of the same material. It is relatively light but strong and has good thermal insulation effect. . It also has the same gas-liquid phase dual-mode storage and intelligent management system as YDD; and the only difference between it and traditional liquid nitrogen tanks is the storage mode!
Different storage modes
There is only one storage mode for traditional liquid nitrogen tanks, which is the liquid phase - the sample is completely immersed in liquid nitrogen.
However, this is also its advantage. The temperature of frozen samples is relatively low, the storage time is longer and the maintenance cost is relatively low.
However, there are also disadvantages. During use, you must always pay attention to the liquid level in the tank, replenish liquid nitrogen in time, and keep it covering the sample to avoid rapid evaporation of liquid nitrogen that affects sample safety.
There are two storage modes for small gas phase tanks, gas phase and liquid phase.
The gas phase uses low-temperature nitrogen evaporated from liquid nitrogen to preserve biological samples for a long time. This preservation method does not come into direct contact with liquid nitrogen and can avoid the risk of sample cross-contamination.
In the liquid phase, the sample is completely immersed in liquid nitrogen at -196�°C and in direct contact with liquid nitrogen.
Two modes can be selected according to different sample requirements.
The advantage of gas phase tanks is that they are easy to use and operate, while the disadvantage is that they are more expensive to maintain.
Although the storage modes of the two are different, they also have their own merits. When choosing, you can choose a liquid phase or gas phase liquid nitrogen tank based on your own needs.
As we all know, liquid nitrogen is a low-temperature liquid and is volatile. Laboratories usually use the low temperature of liquid nitrogen to preserve experimental samples. The use of liquid nitrogen tanks can effectively reduce the volatilization of liquid nitrogen, but over time during use, the liquid nitrogen gradually decreases.
If cell samples are stored below the level of liquid nitrogen or within the gas phase far away from the tank mouth, it is safe for the samples not to be affected by temperature fluctuations. However, when the liquid nitrogen is less than 1/3 of the total amount, the vaporization time of the liquid nitrogen will increase, and the temperature at the top of the liquid nitrogen tank will rise rapidly as the lid is opened, putting cell activity at risk. During this period, if the liquid nitrogen is not replenished in time, or if the liquid nitrogen is completely evaporated before being replenished, and the temperature of the liquid nitrogen tank rises to normal temperature, the cell samples will not only be damaged, but will most likely die!
In order to avoid such problems, laboratory users often use YDD cell bank liquid nitrogen tanks, also known as stem cell liquid nitrogen tanks, to preserve cells and freeze semen samples.
The YDD stem cell liquid nitrogen tank itself has an intelligent monitoring and management system. Its functions cover liquid level monitoring. In addition to displaying the liquid level in real time, when the liquid level is lower or higher than the set value, an audible and visual warning will be issued, accompanied by a text message. Send and never miss a message, even remotely. If liquid nitrogen is not added in time, this function is triggered and the manager will receive relevant prompts. Samples will not be affected for a short period of time.
In addition, the YDD stem cell liquid nitrogen tank supports two storage modes: gas phase and liquid phase. When using the gas phase mode to store biological samples, the bottom liquid nitrogen volatilizes into nitrogen gas and then supplies the top sample. Liquid nitrogen is not directly related to the sample, and liquid nitrogen cannot soak the sample. , the sample may be damaged.
However, in order to ensure the safety of cell samples, it is recommended that you regularly observe the use of liquid nitrogen and refill the jar with liquid nitrogen in time!

At present: liquid nitrogen tanks are common low-temperature containers in laboratories and are often used to preserve specimens, samples, cells, etc., which require the constant temperature characteristics of liquid nitrogen tanks.
Speaking of which, here comes the question. Many people will ask what size of liquid nitrogen tank should be used in scientific research laboratories?
Laboratory liquid nitrogen tanks are generally larger than 30 liters.
There are two reasons:
1. Consider capacity
The capacity of liquid nitrogen tanks ranges from 2 to 175 liters. Different capacities can store different numbers of samples. The larger the capacity, the more samples can be stored.
For laboratories, there are many people who freeze samples, with a wide variety and large quantities. Therefore, it is recommended to choose a jar of more than 30 liters, which can store a variety of samples without the need for frequent refills.
2. Consider caliber
There are 6 options for liquid nitrogen tank diameter,50mm,80mm, 125mm, 127mm,210mm,216mm;
There are many types and large quantities of samples stored in the laboratory. Freezing racks are often used for matching. If the diameter is too small, it will not fit in. Therefore, it is recommended to use a diameter of 125mm or above. A larger diameter makes it easier to take samples and is used with a freezing box. More samples can be saved.
To sum up, liquid nitrogen tanks used in laboratories generally have a capacity of more than 30 liters and a diameter of more than 125mm. But the important thing is to choose based on your actual needs.
If you have any needs, please contact KGSQ liquid nitrogen tank:
Most of the liquid nitrogen tanks used in laboratories are relatively large in volume and size. It is difficult to lift them manually and pour liquid nitrogen into the liquid nitrogen tank, and it is also easy to cause frostbite. Therefore, the self-pressurizing liquid nitrogen tank has become a good helper for rehydration of laboratory liquid nitrogen tanks, solving the rehydration problem of laboratory users.
However, many users do not understand how to operate a self-pressurized liquid nitrogen tank. Today I will explain it in detail.
1. Pressure replenishment sequence: close the vent valve, open the boost valve, and open the liquid outlet valve
The self-pressurizing liquid nitrogen tank needs to be pressurized first, and the vent valve must be closed first to pressurize the liquid; then open the pressurizing valve to allow the nitrogen in the pressurizing tube to enter the inner tank, and then start the exchange cycle of nitrogen and liquid nitrogen. Until the pressure increases to â?¥0.05MPa.
After the infusion is completed, first stop the pressurization, then stop draining the liquid nitrogen, and then open the pressure relief exhaust valve, that is, the vent valve.
2. Let it stand for storage and open the vent valve.
The function of the vent valve is not only to relieve pressure and discharge residual liquid nitrogen, but also to prevent external heat and humid air from entering the pipeline and inner tank.
When the self-pressurized liquid nitrogen tank is stored statically, although there is no pressure, the liquid nitrogen naturally volatilizes, and a gas outlet is needed to release the nitrogen. The vent valve just acts as this "gas outlet". There is also the previously mentioned infusion to complete the pressure relief to avoid the entry of external air, etc.
3. The pressure should not be close to 0.09MPa
The self-pressurizing liquid nitrogen tank complies with the national standard GB/T 14774-2012. It is a self-pressurizing liquid nitrogen container and the pressure must not exceed 0.1MPa. For the safety of users, most manufacturers set the pressure at no more than 0.09MPa and strive to be safe.
If the pressure = 0.09MPa, the self-pressurizing liquid nitrogen tank will automatically open the safety valve to release pressure to avoid dangerous incidents.
In addition, during normal use, the temperature difference between the inside and outside of the container is large, and the thermal equilibrium time is longer when adding liquid nitrogen. Use liquid nitrogen in advance to pre-cool it, and then add it gradually and slowly to prevent ice blockage!

The liquid nitrogen tank for animal husbandry is a type of YDS series liquid nitrogen tank. It is an economical and practical liquid nitrogen tank dedicated to the breeding industry. It is designed for long-term static storage of frozen semen and convenient out-and-out sampling. It is more suitable for those who need to manually transfer and preserve biological samples. Used by users, especially those in mountainous areas.
This series of cattle essence storage tanks are made of high-quality aviation aluminum and contain multiple layers of high-strength thermal insulation layers. They have the advantages of being compact, lightweight, easy to carry, economical and applicable, efficient in storage, and have low liquid nitrogen volatilization rate, ensuring sample safety in all aspects.
In order to ensure that animal semen is not inactivated, the liquid nitrogen tank must be kept at a low temperature and a constant temperature. Liquid nitrogen tanks for animal husbandry have the following characteristics:
1. The container consists of an inner bladder, an outer bladder, a lifting tube, and a neck tube connecting the inner and outer bladders.
2. The inner and outer bladders are made of high-strength aluminum alloy, which is strong and durable.
3. There is a high vacuum between the inner tank and the outer tank, and the vacuum chamber is equipped with multiple layers of thermal insulation materials, so it has good thermal insulation performance.
4. The neck plug is made of plastic with good thermal insulation. It has the dual functions of reducing the evaporation of liquid nitrogen and fixing the lifting cylinder.
5. The neck tube is made of epoxy fiberglass, which has extremely low thermal conductivity and can control the external heat entering from the neck tube to a minimum.
6. The vacuum part is equipped with a gas adsorbent, which can absorb the gas emitted by metal or other substances in the vacuum chamber, thereby maintaining a high vacuum for a long time.
Liquid nitrogen tanks can be divided into two types according to cell storage modes, gas phase and liquid phase storage modes;
In the gas phase, samples are stored in volatile nitrogen; in the liquid phase, samples are directly immersed in liquid nitrogen for low-temperature preservation;
However, due to different capacities, not all cells can be stored in gas-phase storage mode. Only cells with more than 10,000 cells can use gas-phase liquid nitrogen tanks. If there are more than a thousand cells and need to be preserved in the gas phase, how can this be achieved?
You can choose the cryobank series liquid nitrogen tank, which is specially designed for a small amount of cells that require gas phase storage. It has the storage mode of the YDD series and the conventional capacity of the YDS series. It can be regarded as a mini version of the YDD stem cell liquid nitrogen tank or the YDS series liquid nitrogen tank. An upgraded version of the nitrogen tank.
The following are the features of cryobank series liquid nitrogen tanks:
1. 4 models, namely 65 liters, 95 liters, 145 liters and 175 liters, supporting the storage of 2400, 3600, 4800 and 6000 2ml cryovials;
2. Each model is equipped with 6 square buckets for storing freezing boxes and freezing tubes;
3. There are two storage modes: gas phase and liquid phase. When storing in gas phase, the temperature at the top of the tank can reach below -190�°C; therefore, it can be called a small gas-liquid-phase liquid nitrogen tank, a small gas-phase tank, and a small low-temperature biobank;
4. Comes with a liquid level sensor that can monitor the liquid level in the tank in real time, which is safe and reliable;
5. Intelligent control display system, real-time monitoring of internal temperature and liquid nitrogen consumption;
6. Vacuum insulation structure and hot gas bypass design ensure uniform and stable internal temperature;
7. It is adapted to the self-pressurizing liquid nitrogen tank and has automatic replenishing function, which is convenient and fast, saving manpower;
8. Supports remote alarm (voice/SMS/WeChat, etc.), and has intelligent local and cloud data backup and export functions.
In addition, the small gas-liquid phase liquid nitrogen tank also has the same one-click defogging as the YDD biological sample library, which helps users quickly locate cells and reduces the loss of liquid nitrogen caused by opening the lid.

The stainless steel liquid nitrogen tank is also a self-pressurizing liquid nitrogen tank. The tank itself has a pressurizing system and is adjusted through a pressurizing valve. When the booster valve opens, the pressure increases, and when it closes, the pressure decreases. During use, what is the reason why the booster valve is opened but unable to boost pressure?
The reasons why the pressure does not rise after the booster valve of the self-pressurized liquid nitrogen tank is opened are as follows:
1. The booster valve is damaged
When the vent valve and the inlet and outlet valve are closed, and the pipeline is unobstructed but does not pressurize, it means that there is a problem with the booster valve itself and the booster valve needs to be replaced. You can contact the manufacturer for replacement.
2. Pipe blockage
The main reason for pipeline blockage is that external air and moisture enter and are not discharged in time. Under the influence of low temperature in the tank, they condense into ice and block the pipeline.
The correct way to clear the pipe is to use hot nitrogen or hot air to blow away the ice and clear the pipe. After unblocking, it is recommended to transport liquid nitrogen to test whether it is unblocked. Do not use tapping to unblock.
3. Insufficient pressure
Check whether the pressure in the liquid nitrogen tank is sufficient. If the pressure in the liquid nitrogen tank is too low, the pressure cannot be increased even if the pressure increase valve is opened.
4. Container leakage
The container leaks and the vacuum is destroyed, which will also result in the inability to pressurize.
It is easy to judge whether the container is leaking. You can observe the frosting phenomenon on the tank body. The location of a large area of frost is the leakage location.
At this time, the jar can no longer be used normally. You can contact the manufacturer for after-sales treatment.
In short, there are many reasons why the pressure does not rise after the booster valve of the self-pressurizing liquid nitrogen tank is opened. Check them one by one to find out and solve the problems.

Liquid nitrogen supply tank is a cryogenic container made of stainless steel, mainly used for liquid nitrogen transfer and replenishment;
The container itself has a pressure boosting system, which supplies liquid nitrogen to other containers by controlling valves. It is usually used in conjunction with experimental instruments, electronic equipment and other devices.
It is characterized by being equipped with double safety automatic control valves to provide double safety protection measures; it can be continuously pressurized and has the uninterrupted nature of continuous liquid discharge; it is designed with 304 stainless steel inner and outer tanks + vacuum insulation structure, and has been rigorously tested at low temperatures; it is installed with Mobile casters with high load-bearing capacity make movement quick and convenient.
Correct use steps of liquid nitrogen supply tank:
1.Add liquid
Input liquid from the liquid inlet valve. When filling the tank, you must first open the vent valve, connect the metal hose for infusion to the liquid inlet valve, open the liquid inlet valve, and then add liquid nitrogen to the tank. The filling is completed. Finally, close the liquid inlet valve.
2. Liquid level indication
Liquid nitrogen supply tanks are generally equipped with a buoyancy level gauge. By observing the yellow indicator ring on the transparent display, you can grasp changes in the liquid level in the tank.
3.Storage
When storing liquid nitrogen, the liquid inlet valve and booster valve should be closed, and the vent valve should be opened;
4.Transportation
When the liquid nitrogen supply tank needs to be transported, the opening and closing states of each valve should remain the same as during storage, and the bottom casters should be fixed to prevent losses caused by road bumps.
5.Infusion
When you need to add fluid to other containers, pay attention to the following steps:
(1) Close the vent valve;
(2) Open the booster valve;
(3) Observe the pressure gauge;
(4) When the pressure rises to 0.05MPa, open the drain valve to replenish liquid nitrogen;
Liquid nitrogen supply tank is an important cryogenic equipment, which is widely used and frequently used. Correct use is more conducive to the smooth progress of experimental work.
Frozen embryos are one of the prerequisites for implementation, the other is the cultivation of embryos.
After the eggs and sperm are completely extracted, in order to ensure the viability of the eggs and sperm, they will immediately enter the cryopreservation stage, suspend their life activities, and then complete insemination in an external culture system to complete the embryo development. After the embryo is transplanted into the uterus, it still needs to be stored at low temperature. The method of preservation is to put it into a low-temperature medium - liquid nitrogen. Since the temperature of liquid nitrogen is much lower than normal temperature, organisms in direct contact will be frozen. Otherwise, the plastic will be frozen brittle. In order to ensure the vitality of the sperm and egg "combination" embryo, a special liquid nitrogen container is needed to store it. We can also call it an embryo storage tank, because it is used for embryo storage at this time.
The embryo storage tank is composed of two layers: an inner and outer bladder. The inner and outer layers are insulated by a vacuum. It has good thermal insulation and can reduce liquid nitrogen consumption. Even so, the liquid nitrogen balance and temperature in the tank need to be tested every day to ensure that the ambient temperature of the cryopreserved embryos is normal and stable.
In order to ensure the safety of the embryos and improve work efficiency, we can install a liquid level alarm, which can detect the liquid level in the tank. When the ambient temperature reaches the upper and lower limits, an alarm will sound to remind the staff to replenish liquid nitrogen in time. It also supports text messages. , telephone, and email alarm functions. The addition of a liquid level alarm can avoid embryo loss caused by insufficient liquid nitrogen.
This safety measure ensures the safety of the embryonic baby to a certain extent, preventing the embryonic baby from being harmed by the external environment and receiving the same careful care as in the mother's body. It not only improves the success rate of IVF, but also improves the efficiency of laboratory work management.
Moreover, using embryo storage tanks to freeze embryos ensures their vitality during the period between the completion of cultivation and delivery to the mother, reducing damage to the embryos due to temperature changes, etc., and ensuring the success rate of IVF.
Simmental cattle are an excellent breed of cattle. Livestock farmers will buy Simmental cattle frozen semen and cross-breed them with local cattle to improve the quality of cattle and gain greater breeding benefits!
The purchased frozen beef semen cannot be stored in a normal temperature tank. What kind of tank should be used to store it?
â??â??Semen storage tank!
After Simmental cattle semen is extracted, it will quickly become inactive at room temperature and cannot be used. However, through the semen storage tank, the semen is specially treated and soaked in liquid nitrogen. The deep low temperature of liquid nitrogen -196�° can be used to preserve sperm for a long time. Activity, wait until use before taking out and thawing.
Specific steps for thawing frozen cattle semen for breeding:
1. Lift the bucket to the mouth of the jar and use long tweezers to quickly pinch out the frozen wheat tube;
2. Dissolve the frozen wheat tube in warm water at 30-40�°C, and take it out when it is half melted;
3. Check the sperm activity. If the activity is above 0.3, the breeding success rate is high and it can be used for insemination.
4. Load the semen into the gun and output it as soon as possible. Do not store it for a long time.
Notice:
Insemination time: The appropriate insemination time is after the cowâ??s estrus period, when the breeding success rate is higher.
Storage time of frozen semen at room temperature: After thawing, the longer the frozen semen is stored at room temperature, the lower the activity. Therefore, it should be thawed and infused immediately to avoid long-term storage or repeated freezing.
A self-pressurizing liquid nitrogen tank increases the pressure inside the tank through vaporization of liquid nitrogen. When it reaches a certain pressure value, liquid nitrogen can be continuously discharged.
Some users of self-pressurizing liquid nitrogen tanks find that the tank cannot discharge liquid nitrogen after using it for a period of time. After self-inspection, they find that the tank is intact. So what is the reason why the tank cannot discharge liquid nitrogen?
Reason 1: There is no liquid nitrogen in the tank
There is no liquid nitrogen in the tank, so of course it cannot be discharged.
The self-pressurizing liquid nitrogen tank itself relies on the vaporization of a small amount of liquid nitrogen to achieve pressurization. Without liquid nitrogen, pressure cannot be generated!
Moreover, self-pressurizing liquid nitrogen tanks and liquid nitrogen storage tanks are the same. Even if the tank is filled with liquid nitrogen and left unused, it will naturally evaporate.
Therefore, when you find that the self-pressurizing liquid nitrogen tank cannot drain, you must first check whether the liquid nitrogen in the tank has been used up, and replenish it in time.
If you only focus on the inability to drain the liquid and do not pay attention to the remaining amount of liquid nitrogen in the tank, this problem will occur a second time.
Reason two: ice blockage phenomenon
This situation usually occurs at the booster pipe, and sometimes at the drain pipe. This is because the moisture in the air enters the container and is not fully eliminated. When it comes into contact with low temperatures, it will freeze and block the container. Pipes naturally cannot drain fluid.
Stem cells are cells with the ability to self-replicate and differentiate into multiple directions. Under certain conditions, they can differentiate into cells with multiple functions and have the ability to repair various tissue functions and regenerate organs. Therefore, they are also called "universal cells." Such important stem cells can only play a greater role if they are preserved intact.
Stem cell storage tanks are a common storage method for preserving stem cells. Using liquid nitrogen to place stem cells in a low-temperature environment can effectively extend the storage time and maintain their vitality and function.
Since different users have different amounts of stored stem cells, there are three storage tanks to choose from:
1. For liquid phase storage of hundreds or thousands of stem cells, YDS series aviation aluminum liquid nitrogen tanks can be selected;
2. For gas phase storage of thousands of stem cells, small gas-liquid phase stem cell storage tanks can be used, which are also made of aviation aluminum;
3. If the number of stem cells exceeds 10,000, it is more appropriate to use a gas phase stem cell storage tank.
Each of these stem cell storage tanks has its own advantages. Liquid phase storage can maintain a constant temperature of -196�°C, but they lack intelligent management. The small gas-liquid phase storage tank is a mini version of the YDD storage tank. It has the same gas-liquid phase dual mode, intelligent management of samples, automatic replenishment and alarm. In addition, the use of aviation aluminum materials with stronger thermal insulation and lighter weight also combines the advantages of YDS.
Therefore, when storing stem cells, you must choose an appropriate storage tank based on the number of cells and storage method.
In laboratories, the most common experimental objects are cells. The safety of cells is related to the accuracy of experimental results. Therefore, they need to be stored in a low-temperature environment. At this time, experimenters usually choose a cell freezing container, using -196�° liquid nitrogen to maintain low temperature. Its vacuum structure can provide a stable low-temperature environment for cells. However, there are also disadvantages. Liquid nitrogen is easily volatile. Although the vacuum structure can effectively reduce it, the surrounding environment will also have an impact.
Therefore, when using cell freezing containers, there are requirements for the storage environment.
Ambient temperature requirements:
A suitable temperature will reduce the volatilization of liquid nitrogen, while an excessively high temperature will accelerate the volatilization.
Just like summer and winter, the temperature difference between the two seasons is large, and the volatilization in summer will be much higher than that in winter.
The suitable temperature for cell freezing containers is about 20�°, and they can be stored in a cool room or dark place, away from direct sunlight and high temperature environments, to reduce the impact of heat on the tank.
Ventilation requirements:
It should be placed in a well-ventilated area, away from sources of fire and flammable materials. In order to prevent the discharge of volatile liquid nitrogen, the environment is too sealed and cannot dissipate quickly. It also competes with oxygen for space, causing workers to suffer from hypoxia and suffocation.
Storage requirements:
The inner and outer bladders of the container are only connected by the neck tube, which is relatively fragile. To prevent the neck tube from rupturing due to stress, we should store it vertically. At the same time, pay attention to avoid collisions during the movement of the jar to prevent the neck tube connection from falling off and causing damage to the vacuum.
This is the storage environment requirement of cell freezing containers.
Regarding long-term cryopreservation of cells, there are two optional containers, liquid nitrogen tanks and gas-phase liquid nitrogen tanks.
The former is to freeze cells in liquid nitrogen; the latter is to freeze cells in a low-temperature environment generated by liquid nitrogen;
Both of them also rely on liquid nitrogen for cooling, but some people say that using gas-phase liquid nitrogen tanks is safer. Why is this?
In fact, no product can be guaranteed to be perfect. It cannot be said that using gas-phase liquid nitrogen tanks to freeze cells is safer. It can only be said that the safety index is higher than that of conventional liquid nitrogen tanks.
Mainly manifested in three aspects:
1. Storage mode security
The gas-phase storage mode is used to freeze cells, which uses low-temperature nitrogen volatilized by liquid nitrogen for cryopreservation. There is no contact between cells and liquid nitrogen, which can avoid cross-infection of cells during storage and avoid accidental entry of liquid nitrogen into the cryopreservation tube. pipe burst problem;
2. Temperature safety
The temperature inside the gas-phase liquid nitrogen tank is divided into zones. The temperature difference between the upper and lower parts is about 10�°C, which can be said to be very stable. The temperature at the mouth of the tank can be maintained at -190�°C. The lower the temperature, the lower the temperature. No matter where the cells are stored, , the activity will not be "excited" due to large fluctuations in temperature, thereby losing activity.
3. â??Equipmentâ?? security
The gas phase liquid nitrogen tank has a complete intelligent monitoring system.
It can detect temperature, 3 temperature sensors, transmit internal temperature in real time;
It can monitor the liquid level, determine the liquid level height, and can pre-set high/low liquid level alarms;
In addition to these functions, there are also heat exhaust functions, lid opening and defogging functions, alarm and remote alarm functions, event recording, and communication functions. These functions all serve the safety of cells.
This is why the safety index of gas-phase liquid nitrogen tanks is higher than that of conventional liquid nitrogen tanks.
In the medical field, cell storage tanks are often used as cryogenic containers to freeze and preserve biological samples such as cells, vaccines, embryos, etc. During use, the physical characteristics of liquid nitrogen cause it to continuously volatilize. Workers need to observe in time to ensure that the temperature and liquid nitrogen in the storage tank are always in a safe range. At this time, the function of real-time monitoring becomes particularly important.
Therefore, the manufacturer designed an intelligent liquid level alarm to quickly solve this problem. In addition, it has many additional functions and is more convenient to use.
The functions of the intelligent liquid level alarm are:
1. Temperature display: detect and display the temperature of the cell storage tank in real time.
2. Fault alarm: When the sensor is disconnected or the input is open or short-circuited, the instrument automatically emits an audible and visual alarm, the alarm indicator light on the panel lights up, and the buzzer responds.
3. Over-temperature alarm: When the temperature of the measuring point of the liquid nitrogen container is lower than the low temperature set value or higher than the high temperature set value, the instrument automatically issues an audible and visual alarm.
4. Parameter setting function: directly set the high temperature set value, low temperature set value, control temperature value and control hysteresis value through the setting keys on the panel.
5. Silencing function: When the instrument is in the sound alarm state, if necessary, you can click the "Alarm" button to stop the buzzer and eliminate the sound. Click again to turn on the sound. In the setting state, click the "Alarm" button to save the setting value.
6. Power soft switch: Long press the "Power" button on the panel to turn off the instrument power, and long press the "Power" button again to turn on the instrument power.
With the blessing of these functions, the intelligent liquid level alarm adds a layer of guarantee to the safety of biological samples.
In the animal husbandry industry, some friends who are improving frozen semen usually choose to use liquid nitrogen tanks to store frozen semen. Because when breeding, there will be problems with the distance between the breeding objects. The distance is far. Due to the characteristics of animal semen, if it is not in a low temperature environment, it will quickly lose its activity and the quality of fertilization will not be guaranteed. Use liquid nitrogen tanks to store frozen semen to ensure that the activity of the semen continues to exist.
So what kind of liquid nitrogen tank should be used to store frozen semen?
Choose a livestock liquid nitrogen tank, which can also be called a liquid nitrogen frozen semen tank.
It is an economical liquid nitrogen tank specially designed for livestock breeding users. It is designed to be statically stored for a long time and can be taken out for sampling; it is suitable for users who need to manually transfer and preserve frozen semen, especially those in mountainous areas.
In addition, livestock liquid nitrogen tanks are divided into portable and static storage types;
Among the many models of livestock liquid nitrogen tanks, the most popular portable model is YDS-16;
YDS-16, with a diameter of 50mm, a static storage time of 128 days, can store 6 buckets, and can store nearly 800 frozen semen. The important thing is that the jar is small in size, short in height, has good heat preservation, and can be placed It can be put into the trunk of the car and is convenient for short-distance transportation.
Among static storage liquid nitrogen tanks, the most popular models have a capacity of 30 or 35 liters and a diameter of 125mm. The static storage time is about 90 days. It can store 6 buckets and can store nearly 5,000 frozen semen. Important Whatâ??s more, static storage indoors eliminates the need for frequent replenishment of liquid nitrogen, which can meet the needs of a large number of frozen semen customers.
Therefore, when improving frozen semen, use livestock liquid nitrogen tanks to store frozen semen, choose portable ones when going out, and choose static storage for long-term storage.
As we all know, the storage modes of liquid nitrogen tanks can be divided into two types according to sample storage requirements: gas phase and liquid phase, that is, soaking in liquid nitrogen and storing in nitrogen. In order to make it easier for users to distinguish between the two, regardless of industry or brand, they are accustomed to using storage modes to identify them. Liquid phase storage is liquid phase liquid nitrogen tanks, and gas phase storage is gas phase liquid nitrogen tanks. This is also their main way of distinguishing themselves!
Of course, there are other differences besides this, letâ??s introduce them one by one.
1. Model differences:
Including capacity size and national standard naming.
The liquid phase liquid nitrogen tank has a capacity range of 1-175 liters and is named YDS. The national standard stipulates that the material is aluminum alloy.
The gas phase liquid nitrogen tank has a capacity range of 350-1800 liters and is named YDD. The material specified by the national standard is stainless steel.
For user use, just select the appropriate model and type based on the number of samples.
2. Mode differences:
Liquid phase liquid nitrogen tank, the sample is immersed in liquid nitrogen;
The gas phase liquid nitrogen tank meets both liquid phase and gas phase modes. There is a liquid nitrogen storage area at the bottom of the tank to provide liquid nitrogen to the sample area. Note: Vapor phase storage also requires supplementing liquid nitrogen.
3. Management differences:
Liquid-phase liquid nitrogen tanks have a wide range of uses and are relatively small in size. Sample classification management relies on buckets and freezing racks. There is no intelligent control and requires manual labor.
Regardless of the size of the gas-phase liquid nitrogen tank, it is equipped with an intelligent control system that can display the internal temperature, perform relevant alarms, and automatically replenish liquid nitrogen.
Liquid nitrogen tanks have a wide range of uses, whether in laboratories or in the livestock industry. As a low-temperature container, it is mainly used to store or transport liquid nitrogen. It is used for low-temperature experiments in laboratories, cryopreservation in animal husbandry, and can also be used for frozen food. However, for larger liquid nitrogen tanks, although it is convenient to store liquid nitrogen, it is not convenient to transport it.
So what should we do when transporting liquid nitrogen tanks over short distances?
There is a tool called a liquid nitrogen tank trolley, which can easily transfer liquid nitrogen tanks to any location, solving the transportation problem.
Not only that, liquid nitrogen tank trolleys have many advantages:
1. Stability and security:
The trolley has balance and stability to ensure the safety of the liquid nitrogen tank during transportation. The cart is equipped with baffles to prevent accidental movement or tipping.
2. Portable and easy to operate:
Carts are designed to be portable and easy to move between laboratories or other locations. It has a simple operation method and can be controlled by one person.
3. Durability and corrosion resistance:
Since liquid nitrogen has a deep low temperature, the trolley is made of stainless steel to ensure low temperature resistance and corrosion resistance.
4.Adjustability:
In order to adapt to liquid nitrogen tanks of different sizes and shapes, the trolley can adjust the distance between the four corner baffles to better meet the size requirements.
To sum up, the liquid nitrogen tank trolley is an easy-to-use and safe transfer tool, suitable for laboratories, animal husbandry, etc., where there is a demand for liquid nitrogen tank transfer.
In the fast-paced scientific research and medical field, it is sometimes necessary to carry samples to other countries for exchange, or transfer samples to laboratories in other regions, and this kind of transfer is not simple road transportation, but long-distance transfer with the help of high-speed trains or airplanes, and the security check is a hurdle for conventional liquid nitrogen containers. Only the liquid nitrogen tanks for air transportation, which do not contain liquid nitrogen inside but can maintain the cold transfer of samples for a long time, can be used.
Facing the high requirements of air transportation, this series of liquid nitrogen tanks has its own special structure to cope with it!

In modern animal husbandry, the cryopreservation of bovine semen is a crucial technology. It is not only related to the protection of genetic resources, but also directly affects the reproductive efficiency and quality. Choosing a suitable liquid nitrogen tank is the first step to ensure the activity and quality of bovine frozen semen.
How to choose?
Based on the amount of frozen semen and the purpose of use!
For most livestock farms, 2-liter to 35-liter liquid nitrogen tanks are a common choice. Such a capacity can not only meet daily storage needs, but also facilitate management and maintenance.
But to determine the exact model, you need to combine the usage method and the amount of frozen semen!
If you often need to go out to collect semen, or are located in a remote mountainous area, you may need a more portable and moderately capacity liquid nitrogen tank. In this case, a 6-liter and 10-liter liquid nitrogen tank with a diameter of 50mm would be a good choice. It has a single handle, which is not only easy to carry, but also sufficient to meet the needs of herders to go out to collect semen.
If your needs tend to be long-term static storage, then 30-liter, 35-liter 125mm caliber cattle frozen semen liquid nitrogen tanks are more suitable.
The 30-liter 125-caliber liquid nitrogen tank has a large internal storage capacity and can provide a static storage time of up to 85 days, reducing the need for frequent replenishment of liquid nitrogen, and is more suitable for the long-term storage needs of family farms or large livestock farms.
After determining the use needs, it depends on the amount of bull semen!
For semen collection outside, the amount is basically within 792 0.5ml straws and within 1788 0.25ml straws. 6-liter and 10-liter 50mm liquid nitrogen tanks are OK.
For long-term storage at home, 30-liter 125 is optional if the amount of 0.5ml straws is within 9048 and 0.25ml straws is within 20706. If it is greater than this data, use 35-liter 125. If it is far less than this amount, there are 15-liter and 20-liter bull frozen semen liquid nitrogen tanks available!
In addition, when choosing a liquid nitrogen tank, you should also consider the material and design of the tank, as well as after-sales service and technical support.
As a factory with more than 20 years of experience in manufacturing liquid nitrogen tanks, KGSQ will provide you with comprehensive solutions, including the use, maintenance and troubleshooting of liquid nitrogen tanks, to ensure that your investment is worthwhile.
Currently, it is the peak season for species reproduction, and veterinarians and related practitioners seem to be in a cycle, continuously doing artificial insemination work.
Insemination is not like the static storage of sperm, which is stable in one position. When carrying out insemination work, it is usually necessary to travel long distances into mountains or other areas. During this period, in order to ensure that the sperm activity is safe and the quality is excellent, they usually carry frozen semen storage tanks, which are also what we often call livestock liquid nitrogen tanks.
Livestock liquid nitrogen tanks are a series of economical and practical liquid nitrogen containers designed for the breeding industry. In addition to portable small-capacity tanks, such as 3 liters, 6 liters, and 10 liters, it also has large-capacity tanks suitable for long-term static storage, such as 30 liters and 35 liters.
There is also a 16-liter frozen semen storage liquid nitrogen tank suitable for vehicle use.
Among them, portable and vehicle-mounted frozen semen storage tanks are more suitable for artificial insemination in the current season. Portable single handle, small capacity, one person can carry it back and forth, 50mm small diameter, small daily evaporation loss of liquid nitrogen. The car-mounted frozen sperm tank is not a traditional oval, but narrow at the top and wide at the bottom. It has a stable center of gravity and is not easily shaken. It is placed in the trunk to transport sperm to ensure safety during transportation.
One is suitable for short-distance semen collection or artificial insemination, and the other is suitable for long-distance transportation to relatively distant areas for breeding.
Another large-capacity frozen semen storage tank is placed at home to store the collected semen. It is heavy and difficult to move. In addition, the weight of the sperm tube and liquid nitrogen makes it even more inconvenient to move. If you need to use tools for indoor movement, , that is, the liquid nitrogen tank trolley is more secure.
The liquid nitrogen tank trolley is a device specially used for short-distance transfer of liquid nitrogen containers indoors. Made of stainless steel and has a certain load-bearing capacity. At the same time, it is also equipped with swivel casters with strong resistance, corrosion resistance and noise resistance, which makes the liquid nitrogen tank more stable and less likely to shake during transportation, ensuring the safety and stability of the liquid nitrogen container.

In biological sample centers or scientific research institutions, there are a large number of cells, strains, vaccines and other samples that need to be cryopreserved. The scientific research of these samples is of great significance, and their safety cannot be ignored. In addition, there are requirements for batch management and data collection. Vapor phase liquid nitrogen tanks are often chosen over aviation aluminum Dewars.
Vapor-phase liquid nitrogen tank, also known as "stem cell liquid nitrogen tank", is named after it is often used to establish stem cell banks. It is different from ordinary liquid nitrogen containers. It has two storage modes: gas phase and liquid phase. The sample storage method is unconventional and its working principle is break the usual.
Sample storage methods in gas phase liquid nitrogen tanks:
Partition management, gas phase preservation!
The inner tank of the stem cell liquid nitrogen tank is divided into two areas. The upper area is for samples, which is the storage area for stem cells, embryos, bacteria, etc.; the lower area is for liquid nitrogen storage only and does not contain any samples.
The bottom position, which is the liquid nitrogen storage area, is equipped with an evaporator to provide evaporated nitrogen for sample storage to cool down.
The sample is only "close" to the liquid nitrogen, but does not touch it, and the volatilized low-temperature nitrogen is used to store the cells.
Working principle of gas phase liquid nitrogen tank:
The principle is actually very simple, such as the use of liquid nitrogen evaporation cooling mentioned above!
When the nitrogen in the sample storage area is insufficient to support the sample demand, the bottom evaporator starts working to supply liquid nitrogen to the upper part. This has the advantage of avoiding sample cross-contamination.
The reason why I donâ??t mention its other storage mode - liquid phase is because the liquid nitrogen reserve in the container is large, much higher than that of conventional liquid nitrogen containers, and the evaporation loss of stainless steel is higher than that of aluminum alloy. When storing in liquid phase, replenish the liquid. Frequent and troublesome, difficult to use, only gas phase storage is recommended.
In addition, the gas-phase liquid nitrogen tank also has high dual-gallery vacuum + high thermal insulation performance, which reduces heat conduction, reduces the evaporation rate of liquid nitrogen, and maintains stable pressure inside the tank. The built-in intelligent control management system is used for real-time detection and abnormal warning of temperature, pressure and liquid level to ensure the stability of the tank and the safety of stem cells.

The use of liquid nitrogen tanks covers scientific research, animal husbandry, gourmet food, beauty, refrigeration accessories and other industries, but it is mainly used for the preservation of biological samples.
Preserved biological samples can be subdivided into two major categories, animal semen and experimental cells. The two usages are suitable for different containers and each has its own characteristics. Frozen semen storage should be used with a round bucket; in addition to different accessories, cell storage also has many differences such as capacity and caliber!
So what are the characteristics of laboratory liquid nitrogen tanks?
First, the capacity must be large;
Most of the cells preserved in the laboratory are needed for project research or scientific research, and they are large in number and of various types. They need to be stored stably for a long time, and small-capacity jars have limited storage space, making it difficult to store them in categories and difficult to find. Therefore, laboratories use cell storage tanks of more than 30 liters.
Secondly, the diameter must be large and equipped with a freezing rack;
As mentioned earlier, there are many types and quantities of experimental cells. In order to facilitate experimenters to find and manage samples, they can be used in conjunction with square buckets to store cells in a regular manner and make them easy to find. Correspondingly, it is also subject to the restrictions of square buckets, and a wide-neck liquid nitrogen tank with a mouth of 125mm or more must be used.
Finally, it is equipped with a locking cover to ensure cell safety;
Laboratory personnel come and go. For the sake of sample safety, to avoid accidentally taking or losing them, they are usually equipped with locking covers and safety locks to ensure cell safety.
Note: The lock cover of the cell storage tank is standard, but the lock needs to be purchased by yourself!
In life science research, liquid nitrogen is a commonly used freezing medium, and the container that stores it has become an important experimental tool. During the experiment, in order to stabilize the low-temperature storage environment of the sample, regular replenishment is required to ensure adequate supply. Because liquid nitrogen is volatile, the amount of liquid nitrogen decreases over time. Therefore, self-pressurizing liquid nitrogen tanks designed for liquid nitrogen supply are widely used and are very popular in scientific research institutions, laboratories, health industries and other places.
What is a self-pressurizing liquid nitrogen tank?
Answer: It is a liquid nitrogen supply equipment. It can also be called a pressurized liquid nitrogen tank!
Its principle of supplying liquid nitrogen is very simple, which is to use the evaporation of liquid nitrogen to generate pressure to realize the discharge of liquid nitrogen.
There is a valve on the top of its tank that controls the pressure increase. Only when a certain pressure is reached can the liquid discharge be realized. So, when the pressure reaches what level, can this function be realized?
When the pressure reaches 0.02MPa-
In the laboratory, cell samples need to be placed in liquid nitrogen for cryogenic storage. However, some samples must not only be cryopreserved, but also stored in the gas phase without contact with liquid nitrogen. The former can be solved with a conventional liquid nitrogen tank, and the latter can also be solved with a gas-phase liquid nitrogen tank. However, the capacity of gas phase tanks is relatively large, above 350 liters, and the samples that laboratories need to store in gas phase are not always large. When the quantity is small, using gas phase tanks to store them is really overkill. So how to preserve these samples?
There is a small gas-liquid nitrogen tank, you can also call it a small gas-liquid tank! It is also specially used for gas phase storage of stem cells, embryos, semen and other biological samples. It has moderate capacity, low liquid nitrogen loss, easy operation, and is more suitable for laboratory gas phase storage of small quantities of samples.
Its gas-phase preservation principle is very simple. It is based on the characteristics of liquid nitrogen having a boiling point of -196.56�°C under normal pressure and the natural formation of nitrogen. The area of the small gas-liquid phase liquid nitrogen tank is divided into two, liquid nitrogen is placed at the bottom, and the sample is frozen. The rack is suspended above the liquid nitrogen, and with the help of the natural volatilization of the liquid nitrogen, a low-temperature environment is formed in the container. At this point, is there a familiar and unfamiliar feeling?
That's right, the small gas-liquid phase tank is a smaller version of the YDD series gas-phase liquid nitrogen tank. Except for the difference in material and capacity, the rest of the characteristics are the same. For example: compatible with gas-liquid phase dual-mode storage, intelligent management system, etc.; therefore, the principles between the two are also interoperable!
In short, the small gas-liquid phase tank makes up for the YDD series's demand for small-volume cell storage in terms of capacity. It is a lightweight and energy-saving gas-phase storage liquid nitrogen container specially designed for gas-phase storage of small-capacity cell samples.
Livestock liquid nitrogen tanks are widely used in the breeding industry, especially in the freezing and storage of sperm and long-distance large-scale breeding. They play an irreplaceable role. It emerged with the emergence of modern breeding technology. As market demand continues to improve, its capacity and performance have become richer and more perfect over time. With better insulation effects, it provides strong support for the rapid development of livestock production and breeding of fine breeds. Strong germplasm conservation support.
Today, the capacity range of livestock liquid nitrogen tanks covers 2-35 liters, with 4 types of calibers available, and can be used in both portable and long-term storage types.
Letâ??s talk about portable liquid nitrogen tanks first;
We know that semen collection is indispensable for animal husbandry and breeding. It must first be collected â?? stored â?? before it can be used for subsequent breeding and preserve the fertility of improved seeds. Therefore, the field work of breeding personnel is indispensable, that is, going out to collect semen. The environment involved in semen collection cannot always be flat roads, but is mostly in mountainous areas or pastures where breeding is concentrated. The terrain is rugged and requires portable liquid nitrogen tanks that are lightweight and small in size, such as 6 liters and 10 liters.
Secondly, for transportation purposes, such as artificial insemination, breeding, etc., the well-preserved sperm need to be transferred to other areas for insemination. The distance may be long or short, and it is often necessary to travel by vehicle. The storage capacity of the container and the swaying on the road need to be taken into consideration. The 16-liter livestock liquid nitrogen tank designed for transportation is more suitable. The small and short tank has a low center of gravity and a stable chassis, which is more stable and reduces the stress on the neck tube to ensure the safety of the container and sperm.
In addition, long-term sperm storage at home involves centralized storage after semen collection. The number of sperm will continue to increase, and the frequency of rehydration must be considered. If it is too high, it may easily cause frequent temperature fluctuations in the livestock liquid nitrogen tank; it is also necessary to consider the retrieval frequency. Convenient, generally choose large diameter. Considering the 30 liters and 35 liters with 125mm port, it is the best choice.
Depending on the purpose of use and the sperm count, you can choose just what you need!
If you still dont know how to choose, you can contact the livestock liquid nitrogen tank manufacturer for recommendations from professionals!
In laboratories, most commonly used liquid nitrogen tanks have large capacity, large diameter, and weight. If you want to transfer it, it is difficult to carry it with bare hands, and there is still a certain degree of danger. And there is no guarantee that bumps or accidents will not occur during the transfer process. If something goes wrong during the transfer, you'll lose more than you gain.
So how to safely transfer laboratory liquid nitrogen tanks indoors.
You can choose a liquid nitrogen tank trolley, which is a labor-saving and safe transfer equipment.
The liquid nitrogen tank trolley is made of stainless steel, has a large table design, and is equipped with 4 high-load capacity swivel casters at the bottom, which is wear-resistant and low-noise. It has the advantages of convenient installation, labor-saving transportation and strong load-bearing capacity. Put the liquid nitrogen tank on the trolley, which can help the experimenter easily move it anywhere without much manpower. This kind of trolley is not only suitable for laboratories, but can be easily maneuvered and moved flexibly in various complex environments such as hospitals, scientific research institutes or health industries.
However, the trolley also has a range of use. It has different models to choose from. The capacity is suitable for large-capacity laboratory liquid nitrogen tanks from 30L to 190L. Indoor transfers are more portable and greatly improve work efficiency.
The emergence of liquid nitrogen tank trolleys solves the problem of difficulty in transferring liquid nitrogen tanks in the laboratory, which is both safe and efficient.

When it is fully filled, it only takes 20 seconds to pressurize it to the standard pressure; the liquid nitrogen storage capacity is 3/4, which takes about 1 minute. And it relies on the internal pressurization system to pressurize, without contact with external air, and the purity of liquid nitrogen is guaranteed.
In addition, self-pressurizing liquid nitrogen tanks can be equipped with solenoid valves to achieve automatic replenishment.
YDS series liquid nitrogen tanks are mainly used to store liquid nitrogen and biological samples.
Liquid nitrogen tank, also known as "liquid nitrogen biological container", is a low-temperature container that can store liquid nitrogen and biological samples. According to their uses, they can be divided into liquid nitrogen storage tanks, self-pressurized liquid nitrogen tanks, and gas-phase liquid nitrogen tanks. Among them, liquid nitrogen storage tanks can also be subdivided into storage types and transportation types. The storage type is mainly used for static storage and is not suitable for long-distance transportation during work; the transportation type is specially designed to meet transportation conditions and has an internal shock-proof function. Support, while also allowing for static storage when needed.
Since liquid nitrogen tanks are used to store samples, they need to be used correctly:
before use:
1. Check the jar
Check whether the shell has any dents or dents, and whether the vacuum port is intact;
Check whether there are foreign objects or impurities in the tank. If there are foreign objects, they need to be removed to prevent the inner tank from being corroded;
2. Pre-cooling
Inject a small amount of liquid nitrogen into the tank to cool the inner liner;
After injecting liquid nitrogen, cover the neck plug and leave it for a few hours, such as the boiling phenomenon disappears and the liquid nitrogen tends to stabilize;
When the water droplets or frost produced by the heat exchange of the tank body fade away and there is no white frost on the neck plug, it means that the pre-cooling is completed.
when using it:
1.Storage
Store in a well-ventilated and cool place, do not expose to direct sunlight;
Keep upright and do not tilt, lay horizontally, invert, pile up, hit each other or collide with other objects;
2.Transportation
Handle it gently when moving and avoid sudden movements;
It must be fixed during transportation to ensure that it will not shake during transportation;
After use:
Cleaning:
1. After the liquid nitrogen has evaporated, let it sit for several hours until the internal temperature of the container returns to normal temperature.
2. Pour warm water at 40 -50 into the container, and then wipe it with a cloth.
3. Rinse 2-3 times with clean water.
4. Invert the container to dry naturally. You can also use hot air to dry it. The suitable temperature is 40 -50 . Avoid hot air above 60 .
After cleaning, store it in a dry and ventilated place, and check it regularly for next use.
