Liquid nitrogen tanks are divided into storage type liquid nitrogen tanks, transport type liquid nitrogen tanks and portable liquid nitrogen tanks, and their uses are quite different. Transport liquid nitrogen tanks are not only used for storage but also for transportation of liquid nitrogen, while portable liquid nitrogen tanks are generally small-sized liquid nitrogen tanks, mainly 2 liters, 3 liters, 6 liters, and 10 liters, which are easy to carry during use.

The cryogenic liquid nitrogen tank is made of aluminum alloy, which is light and easy to move. However, the weight of different models is slightly different. For example, the weight of YDS-2-35 model liquid nitrogen tank is 2.3kg, the weight of YDS-3-50 model is 3.2kg, the weight of YDS-6-50 model is 4.7kg, the weight of YDS-10-50 model is 5.8kg, and YDS-20-50 model is 11.2kg. Cryogenic liquid nitrogen tanks are usually 2-100 liters in size, and the calibers are mainly 50mm, 80mm, 125mm, and 210mm. The larger the caliber, the faster the liquid nitrogen evaporates. If the volume is the same, the larger the caliber, the heavier the weight of the entire tank will be.

Cryogenic liquid nitrogen containers are mainly used for the active preservation of animal semen, the active preservation of biological samples, the cold treatment of metal materials, and the refrigeration of medical surgeries in the medical and health industry.
