Why is the storage life of liquid nitrogen tank not up to the standard

liquid nitrogen tank What is the shelf life that does not meet the standard? Self pressurized liquid nitrogen tank

The laboratory liquid nitrogen tank, model yds-30-125, has a storage life of 110 days. When it is filled with 30L of liquid nitrogen, the tank will be empty in 25 days. Some people say that the new tank needs to adapt to the lower temperature, and the storage life can reach about 70 days after adding liquid nitrogen several times? Is that the case? Thank you very much for your help!

For your reference:

     1. Your container should be 30L and 125mm in diameter. If it is a large diameter container, the insulation should be around 95 days.

     2. Pay attention to filling up the liquid nitrogen for the second time. Since the temperature in the container is room temperature and the temperature of liquid nitrogen is - 196 ℃, it is normal that the volatilization of * times is faster.

     3. The length of preservation period should be considered from the following aspects:

     The first is the size of the container. If the diameter of the 30 liter container is 50 mm, the storage time can be more than 200 days (under the ideal condition of no specimen preservation and no lid opening);

     Second, the frequency and time of opening the lid;

     Third, how many samples to keep.

     These are three factors that directly affect the preservation time.

     4. Your container should be good. If there is something wrong with the heat preservation, the container with 125mm diameter will not be stored for 25 days. Please fill it up next time. Self pressurized liquid nitrogen tank
