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 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.
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 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.
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 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.

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!

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:
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!

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.

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.
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.

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. If you have any needs, please contact KGSQ liquid nitrogen tank:
