The liquid nitrogen tanks has a heat insulation function. The liquid nitrogen storage tank at 196 ° C can maintain a constant temperature and reduce volatility. For this reason, laboratories or scientific research institutions often use it to store samples, and some hospitals use it for storage.
In order to ensure the quality of the samples we store, pay attention to the following points when storing liquid nitrogen tanks:
1) It is strictly forbidden to place items on the lid of the liquid nitrogen tank, so that the evaporated nitrogen can overflow naturally.
2) A matching cap should be used. It is strictly forbidden to use a self-made cap to close the cap, so as to prevent the internal pressure of the liquid nitrogen tank from increasing, resulting in damage to the tank and serious safety problems.
3) In order to effectively reduce the loss of liquid nitrogen, the liquid nitrogen tank should be placed in a cool place.
