Liquid nitrogen biological containers are high-tech products, mainly used for the cryogenic storage of livestock semen, and Low temperature preservation of blood and cell. They are also an indispensable tool in cryogenic surgery, industrial cold assembly, cold treatment of metal materials, cryogenic pulverization, and superconducting magnets.

The liquid nitrogen tank consists of an outer liner, an inner liner, tubing, insulation material, a vacuum nozzle, and a carrying cylinder.

1. The outer and inner liners are made of a special high-strength, corrosion-resistant aluminum alloy, making them sturdy and durable.

2. The stopper is made of a special material, serving the dual purpose of reducing liquid nitrogen evaporation and securing the carrying cylinder.

3. The tubing is made of a special glass-reinforced plastic, offering high strength and low thermal conductivity, minimizing the amount of heat entering through the neck.

4. Insulation material is filled in the space between the inner and outer liners, which is then evacuated to a high vacuum, thus minimizing liquid nitrogen evaporation.

5. The vacuum nozzle is a crucial component for sealing the vacuum and must be strictly protected; it must not be impacted, dropped, or tightened by hand.

6. The protective sleeve, besides preventing external impacts and protecting the container during movement or handling, also provides insulation, further reducing evaporation.
