The liquid nitrogen tank is a double-layer structure, which is different from the thermos bottle in life. It is more precise, and the vacuum between the double-layer aerospace aluminum chamber is more demanding.

The liquid nitrogen tank is usually used to preserve the liquid nitrogen for a longer period of time, to use the low temperature of liquid nitrogen to keep the sample inside the bottle active. Because liquid nitrogen will vaporize at -196°C, even in a liquid nitrogen tank, it is constantly changing to nitrogen, so a good liquid nitrogen tank can make the liquid nitrogen vaporize more slowly and keep it longer. Each liquid nitrogen tank is carefully manufactured through one process in the factory, and each liquid nitrogen tank has been tested for volatility and is better than the volatilization amount specified in the national standard.

In the production, Tianchi KGSQ liquid nitrogen tanks strictly implement the quality specification of "Liquid Nitrogen Biological Containers GB/T 5458-2012", and all products have passed the function test of Product Quality Supervision and Inspection Institute. We have passed ISO9001 and EU CE quality certification. We provide high quality products and perfect after-sales service
