The liquid nitrogen tank is a special storage container for storing liquid nitrogen. In the laboratory, medical and other fields have the application of liquid nitrogen tank. However, liquid nitrogen tanks need to pay attention to some details when storing liquid nitrogen to ensure safe and effective use. Below, we will introduce you to the liquid nitrogen tank storage precautions.

need to ensure that the liquid nitrogen tank is well sealed. Liquid nitrogen is a very low temperature liquid. If the sealing of the liquid nitrogen tank is not good, it will easily lead to the volatilization and waste of liquid nitrogen. Therefore, when storing liquid nitrogen, be sure to check the tightness of the liquid nitrogen tank to ensure that there is no air leakage. The storage location of the

liquid nitrogen tank also needs attention. The liquid nitrogen tank should be stored in a well-ventilated place, away from open flames and heat sources. At the same time, direct sunlight and high temperature environment should also be avoided, so as not to affect the storage effect of liquid nitrogen.

In addition, when using a liquid nitrogen tank to store liquid nitrogen, it is necessary to regularly check the safety valve of the liquid nitrogen tank. The safety valve is a device used to protect the liquid nitrogen tank to release gas under abnormal conditions to reduce pressure. Once an abnormal situation occurs, the safety valve will automatically start. Therefore, it is very important to check the operation status of the safety valve regularly to ensure that the safety valve is in normal working condition.

In addition, it is necessary to regularly check the liquid level of the liquid nitrogen tank. The liquid nitrogen level in the liquid nitrogen tank should be within the specified range, not too high or too low. An excessively high liquid level may cause the internal pressure of the liquid nitrogen tank to be too high, and an excessively low liquid level may cause the air pressure in the tank to decrease, thereby affecting the storage and use of liquid nitrogen. Care must be taken when

use liquid nitrogen tanks to store liquid nitrogen. Liquid nitrogen is an extremely low temperature liquid, which can stimulate and damage human tissues. When using liquid nitrogen tanks to store liquid nitrogen, be sure to wear protective gloves and goggles to avoid direct contact with liquid nitrogen.

To sum up, the liquid nitrogen tank is a special storage container, and some details and precautions need to be strictly observed when storing liquid nitrogen. Only by doing the above matters can we ensure the safe and effective use of liquid nitrogen storage. I hope everyone can strengthen the attention to the storage of liquid nitrogen tanks to ensure the safe storage and use of liquid nitrogen.
