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 0.05MPa (0.5kg/cm2), open the drain valve, that is, continuous infusion.

　　Inspection during use

　　 Always check during use. You can observe with your eyes or touch the outer 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 frozen, it is not advisable to use a knife to scrape it to prevent the inner wall of the neck tube from being damaged and resulting in poor vacuum. Instead, take out the liquid nitrogen and let it melt naturally.

　　 Liquid nitrogen tanks should be stored in a well-ventilated and cool place, and should not be exposed to direct sunlight. Due to its precise manufacturing and inherent characteristics, liquid nitrogen tanks are not allowed to be tilted, placed horizontally, upside down, stacked, collide with each other or collide with other objects, no matter when they are used or stored, they must be handled gently and kept at all times. upright.
