The main purpose of liquid nitrogen container

Liquid nitrogen It is inert, colorless, odorless, non-corrosive, non-flammable, and extremely low temperature. Nitrogen constitutes most of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inactive and does not support combustion. Frostbite caused by a large amount of endothermic contact during vaporization. Nitrogen makes up 78% of the air.

Due to the special nature of liquid nitrogen, storage tanks need to be filled with professional cryogenic liquid nitrogen containers. The liquid nitrogen storage tanks required are different for different uses and different volumes. The previous article explained the liquid The different classifications of nitrogen storage tanks, today I will specifically explain the main uses of liquid nitrogen storage tanks.

1. Animal semen activity preservation.
It is mainly used for the preservation of semen of excellent breeds of cattle and sheep and cherished animals, as well as long-distance transportation and storage.

2. Biological sample preservation.
In the field of biomedicine, vaccines, bacterial species, cells and human and animal organs can be immersed in liquid nitrogen stored in liquid nitrogen tanks for long-term active preservation. When you need to use it, you can take it out after thawing and warming. 3. Cryogenic treatment of metal materials.
Cryogenic treatment of metal materials using liquid nitrogen stored in a liquid nitrogen tank can change the metallurgical 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 being subjected to cryogenic treatment of liquid nitrogen to improve the assembly quality of the parts, thereby improving the overall performance of the equipment or instrument.

5. Refrigeration and freezing in the medical and health industry, and refrigeration in medical operations.
