Before using the liquid nitrogen tank, you must first check whether the shell is recessed and whether the vacuum exhaust port is intact. If it is damaged, the degree of vacuum will be reduced, and in severe cases, it cannot be insulated, which will affect the use value of the liquid nitrogen tank.
Then check the inside of the liquid nitrogen tank. If there is a foreign body, you must remove it to prevent the liner from being corroded. When filling liquid nitrogen, for new or dry liquid nitrogen tanks, it must be filled slowly and pre-cooled to prevent the inner tank from being cooled too quickly.
