Infusion and storage of liquid nitrogen in liquid nitrogen tank

Infusion:

　　 If you want to output liquid nitrogen from the liquid nitrogen tank, please follow the procedure below:

　　 Close the vent valve; open the booster valve; observe the pressure gauge; when the pressure rises to 0.05 MPa (0.5 kg/cm2), open the drain valve to allow continuous infusion.

　　Inspection during use

　　 Always check during use. You can observe with your eyes or touch the shell with your hands. If you find frost on the outside, you should stop using it; especially when the inner wall of the neck tube is frosted and iced, it is not advisable to scrape it with a knife to prevent the inner wall of the neck tube from being damaged and causing poor vacuum. Instead, take out the liquid nitrogen and let it melt naturally.
