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 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.
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.
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.
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.
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.
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.
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 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.

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.
In addition to being used for storage and transportation, liquid nitrogen tanks can also be used for self-pressurizing liquid nitrogen tanks that combine storage and transportation, and are only used for rehydration of other liquid nitrogen containers. The self-pressurizing liquid nitrogen tank belongs to the "YDZ" series. It has the same vacuum insulation + internal and external double tank structure as the "YDS" series, but the YDZ has no caliber and controls the inlet and outlet of liquid nitrogen through valves. Features of self-pressurizing liquid nitrogen tank: 1. It is manufactured in accordance with the national standard GB/T 14774-2012, and users have evidence to follow; 2. Both the inner and outer bladders are made of 304 stainless steel, which has strong load-bearing resistance, good low-temper ature resistance and good heat insulation, and is easy to clean; 3.

Equipped with a pressure stabilizing system device to stabilize the pressure and liquid nitrogen flow rate to prevent sudden increases and drops in pressure from causing liquid nitrogen to splash and injure people; 6. The movable casters at the bottom are not only flexible, but also have high load-bearing capacity, so you can use them with confidence; 7. Special vacuum technology ensures a low liquid nitrogen evaporation rate; 8. After strict low-temperature testing before leaving the factory, it can enjoy a 5-year vacuum warranty and a 1-year free warranty service; Advantages of self-pressurizing liquid nitrogen tanks: 1. Low pressure is safer In addition to self-pressurizing liquid nitrogen tanks, there are also medium and high-pressure Dewar bottles that can realize liquid nitrogen replenishment. The difference lies in the pressure and whether annual inspection is required. The self-pressurizing liquid nitrogen tank has a low pressure within 0.1MPa and has no pressure when not in the infusion state. It is not a pressure vessel and does not require annual inspection, which is safer. 2. High efficiency in outputting liquid nitrogen Although the pressure is low, the infusion speed of the self-pressurized liquid nitrogen tank is not slow. 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.
