AST-Liquid nitrogen biological container

The liquid nitrogen biological container is generally composed of a high-strength aviation aluminum inner and outer bladder, with a vacuum layer in the middle. It can be divided into storage tanks and transportation tanks.
The storage tank is mainly used for the static storage of indoor liquid nitrogen, and is not suitable for long-distance transportation under working conditions;
In order to meet the transportation conditions, the transport tank has a special anti-vibration design. In addition to being stored statically, it can also be used for transportation when filled with liquid nitrogen, but severe collisions and vibrations should also be avoided.
Generally used in the following aspects:
Active preservation of animal semen.
It is mainly used for the preservation of semen of excellent breeding males such as cattle and sheep and cherished animals, as well as long-distance transportation and storage.
Active preservation of biological samples.
In the field of biomedicine, vaccines, bacterial strains, cells, and human and animal organs can all be immersed in liquid nitrogen stored in liquid nitrogen tanks for long-term active preservation. When needed, they can be used after being removed and thawed and reheated.
Cryogenic treatment of metal materials.
Cryogenic treatment of metal materials with liquid nitrogen stored in a liquid nitrogen tank can change the metallographic structure of the metal material and significantly improve the hardness, strength and wear resistance of the metal material.
Cryogenic assembly of precision parts.
The precision parts are assembled after cryogenic treatment with liquid nitrogen to improve the assembly quality of the parts, thereby improving the overall performance of the equipment or instrument.
