Liquid Nitrogen Container Before Filling

Edit: Henan Tianchi Instrument Equipment Co., Ltd    Date:2018-10-08
Before filling the liquid nitrogen container, the liquid nitrogen container should first check whether the outer casing is recessed or not, and whether the vacuum exhaust port is intact.

If it is damaged, the degree of vacuum will decrease. In severe cases, the intake air will not be insulated, 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.
Next, check the inside of the tank. If there is any foreign matter, it must be taken out to prevent the inner containerk from being corroded.
