Inspection before use Before filling the liquid nitrogen tank with liquid nitrogen, first check whether the shell is dented and whether the vacuum exhaust port is in good condition. If it is damaged, the vacuum degree will be reduced. In severe cases, the intake air cannot be kept warm, so that the upper part of the tank will be frosted, the liquid nitrogen loss will be large, and the value of continued use will be lost. Secondly, check the inside of the tank. If there is foreign matter, it must be taken out to prevent the liner from being corroded.
