This situation may sometimes occur during the use of liquid nitrogen tanks:

There is no need for sample preservation or the use of liquid nitrogen in the near future, but it will definitely be needed in a few months!

In this case, the liquid nitrogen tank will definitely be vacant for a period of time. Can it be used again after it is vacant?

A: You can use it, but you must make sure of its quality!

It is unknown what changes will occur in the liquid nitrogen tank when it is vacant. If the storage environment is not suitable, it is hard to say whether the tank will be affected. The effect cannot be guaranteed if it is used rashly. Once there is an abnormality in the container, the sample is likely to be affected.

In line with the principle of being responsible for samples, it is recommended to check before use to see if there are any dents or bumps on the can body. If not, pre-cool it, which is equivalent to doing a simple evaporation test to see if there is frost on the surface of the liquid nitrogen container, whether the frost is slowly fading or getting thicker, so as to judge the quality of the container.

If the surface of the liquid nitrogen tank is normal after pre-cooling, it can be put into use. Remember to observe the loss of liquid nitrogen in the meantime and replenish liquid nitrogen regularly.

This is the answer to the question of whether the liquid nitrogen tank can be used again after being vacant for a long time!
