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.

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.
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.
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.

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.
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.
