DEWAR: Dewars are designed for the sole purpose of holding extremely cold liquids such as liquid nitrogen; They have the shape, capacity, and material construction to store liquid nitrogen with a slower evaporation rate

EVAPORATION RATE: We test the evaporation rate of our liquid nitrogen tanks by completely filling them with liquid nitrogen and tracking the rate of evaporation

Durable & Sturdy : We have tested 3L, 6L, 10L, 20L liquid nitrogen tank under 20° and their storage time is 27 days, 54 days, 90 days and 162 days. The liquid nitrogen container is made of high-strength aviation aluminum alloy with ISO 13485 (medical equipment) standard and APRAGAZ MDD certification,which can protect liquid nitrogen and samples in tank,no any worry about scratched and deformed due to improper operation.

Insulation & Vacuum Design: Multiple insulation layers surround the tank and gas adsorbent design ensure a great vacuum storage inside and store samples longer time.

6 Canisters: The liquid nitrogen tank comes with 6 canisters,of which 2 without holes for retrieving small amount of nitrogen, 4 with holes for holding samples.

[WIDE APPLICATION] The liquid nitrogen tank can be widely used in farms, research institutes, laboratories, hospitals, beauty salons and other units.

[COMPACT 50mm CALIBER] Small diameter allows for longer storage and cycle, while large diameter will cause liquid nitrogen leakage.

[AEROSPACE MATERIALS] The liquid nitrogen container is made of high-strength aerospace aluminum material, which is corrosion-resistant and can store liquid nitrogen safely.

CAPACITY: The U.S. Solid Cryogenic Container Liquid Nitrogen Tank Dewar can hold up to 3 Liters of liquid nitrogen

6 Canisters: The liquid nitrogen tank comes with 6 canisters,of which 2 without holes for retrieving small amount of nitrogen, 4 with holes for holding samples.

APPLICATION-The liquid nitrogen dewar can store semen/embryos/cells/dry ice and etc. For liquid nitrogen, we have tested 3L, 6L, 10L tank under 17 Celsius and their storage time is 35 days, 65 days and 105 days. For dry ice storage, 10L dewar is recommended and it can be stored for about 10 days.

CANISTERS-Each liquid nitrogen container comes with 6 stainless steel canisters, of which 1 without holes for retrieving small amount of N2, 5 with holes for holding samples.

MATERIAL-Made of aeronautical aluminums, the cryogenic container is of high strength and can protect liquid nitrogen and samples.
