Liquid nitrogen container Factory

A biological liquid nitrogen container（Liquid nitrogen container) is a biological container used for the storage of biological samples, such as stem cells, embryos, vaccines, etc. . It scientifically solves the problem of large amount evaporation loss of liquid nitrogen due to heat convection, conduction and radiation in the container during storage of liquid nitrogen. With the development of science and technology and the progress of human society, the high vacuum multi-layer insulation technology and its new materials and new technology have been adopted, the natural evaporation loss of the preserved liquid nitrogen (-196 ° C) can be reduced to even lower. Therefore, the biological liquid nitrogen tank products are widely used in the fields of animal husbandry, medical and scientific research, mechanical processing and so on. Liquid nitrogen containers can be divided into transport type liquid nitrogen containers, storage type liquid nitrogen containers, self-pressurization type liquid nitrogen containers, glass inner tank liquid nitrogen container, self-discharge liquid nitrogen container, gas infusion type liquid nitrogen containers, the most common are the first three:

1. Transportation type liquid nitrogen container

This type of liquid nitrogen container equipped with a special shock-proof design, in addition to being used for static storage, but also can be filled with liquid nitrogen transport use, however, it is still necessary to avoid violent collisions and vibrations during transportation.

2. Storage type liquid nitrogen container

The storage type liquid nitrogen container is mainly used for indoor static storage of liquid nitrogen.

3. Self-pressurized liquid nitrogen container

The working principle of the self-pressurizing liquid nitrogen container is that there is a self-pressurizing device inside, which can make use of the small amount of liquid nitrogen in the container to vaporize and generate pressure, thus enabling the container to discharge liquid nitrogen, it is usually used in conjunction with other instruments that require cooling.

Usage

1. The active preservation of animal semen. 

Liquid nitrogen biological container is mainly used for cattle, sheep and other good breeds of male animals and the preservation of precious animal semen, as well as long-distance transport and storage.

 2. Active Preservation of biological samples. 

In the field of biomedicine, vaccines, bacterial strains, cells and human and animal organs can be immersed in liquid nitrogen tanks stored in liquid nitrogen, long-term active preservation. When it needs to be used, it can be used after thawing and rewarming. 

3. Cryogenic treatment of metallic materials. 

Cryogenic treatment of metal materials with liquid nitrogen stored in biological vessel can change the metallographic structure of metal materials and significantly improve the hardness, strength and wear resistance of metal materials. 

4. Cryogenic Assembly of precision parts. 

The precision parts are assembled after cryogenic treatment with liquid nitrogen to improve the assembly quality of the parts and thus improve the performance of the whole equipment.

 5. Refrigeration of medical and health industry, refrigeration of medical operation.

Advantage

1. Automatic supply of liquid nitrogen, easy to operate. 

2. Lightweight 

3. High strength and corrosion resistance at low temperatures. 

4. Two-mode free-switching large-caliber liquid nitrogen biological tank supports both gas and liquid modes. The two modes are free-switching. Can be centralized tagging management samples, easy access to get.

5. Intelligent management of sample data.

 Each large-caliber biological tank of liquid nitrogen is equipped with an intelligent monitoring and management system, which can display the temperature curve, set the height of automatic fluid infusion, and sample management functions, data storage, transfer, download, etc. . Pre-set a good opening cover time-out, exhaust, rehydration, and so on, there is a fault alarm alert, humanity also worry-free. 

6. The evaporation loss rate of liquid nitrogen is low

Low evaporation loss of liquid nitrogen the larger the diameter of a conventional liquid nitrogen tank, the higher the loss of liquid nitrogen, both to ensure safety and to ensure that the tank is not completely sealed, and also to ensure that there will be heat convection, transfer and radiation problems when the liquid nitrogen is stored or taken samples, the inevitable entry of external heat. Large caliber liquid nitrogen biological tank vacuum adiabatic + gas mode, liquid nitrogen at the bottom, samples stored in the upper part of the liquid nitrogen, there is a tray isolation, taking samples can not be affected open cover; insufficient liquid nitrogen automatic filling, no open cover, very good to avoid hot air into.
