The liquid nitrogen tank is a low-temperature container. The materials used are mainly divided into two types, one is stainless steel and the other is aluminum alloy. However, they are slightly different. The normal pressure tank is made of aluminum alloy, which is light and easy to operate. The self-pressurizing cryogenic tank is made of stainless steel and has relatively low liquid nitrogen volatilization.
Atmospheric liquid nitrogen containers are mainly made of aluminum, which has strong corrosion resistance and is more convenient for later use. The self-pressurizing liquid nitrogen tank is made of 304 stainless steel. The low-temperature tank made of this material has good sealing performance and the volatility of liquid nitrogen is relatively low. However, the tank made of this material is relatively heavy and difficult to move during use.
The main body of liquid nitrogen biological container is generally made of high temperature resistant materials such as 304 stainless steel, aluminum, and alloys. The inner wall of the tank has been treated with anti-corrosion treatment to effectively avoid corrosion and pollution. The lid is generally made of stainless steel and has good sealing performance. The lid and the tank are connected with a gasket to ensure stable air pressure in the tank.
