*KeyFeatures *Premium Aviation Aluminum: ISO 13485 (medical equipment) standard and APRAGAZ MDD certification. The liquid nitrogen container is made of high-strength aviation aluminum alloy and has a service life. It can still work typically when the storage tank is scratched and deformed due to improper operation. *Excellent Thermal Insulation: The special inner structure ensures sound insulation; reduces evaporation of liquid nitrogen. Good welding quality and stamping process reduce the possibility of leakage in the inner box. *Slower Evaporation Rate: There is ample vacuum space between the outer shell and the inner container. The nitrogen tank is equipped with a gas adsorbent to adsorb other gases and maintain a high vacuum environment. In addition, high-quality vacuum plugs enhance tightness. *Complete Accessories Kit: 6 Canisters: can be put in the tank to store samples. The sleeve prevents the use of uneven scratches of the surface and the liquid nitrogen container from impact and damage. Portable to carry. *Various Application: Liquid nitrogen tank is widely used in animal husbandry, scientific research, and mechanical processing, using liquid nitrogen as a refrigerant for the transportation of samples and precision processing of metal materials at low temperatures. ******************************************************************************************************* *Specifications Capacity: 3L Material: Aluminum Alloy Mouth Diameter: 1.97 in / 50mm Depth of Canister: 4.37 in / 111mm Diameter of Canister: 1.38 in / 35mm Static Hold Time (not in use): 30 days (Frequent use and opening of the lid will cause liquid nitrogen to volatilize and reduce storage time.)
