After receiving the jar, you need to do the following:
- CleaningIf floating objects are found in the liquid nitrogen tank, maybe it is the residue left when testing the tank’s quality before shipment. It is recommended to clean it before use. If the tank is clean, not to clean is ok.InspectionCheck whether there are water drops or frost on the tank body of liquid nitrogen tank. It can be directly touched by hand. If the upper part of the tank is cold and the lower part is hot, it means that the tank is abnormal.PrecoolingNew or dry tanks need to be precooled with liquid nitrogen to prevent excessive temperature difference from causing damage to the inner vessel, which will reduce the service life of the container.
