Storage of liquid nitrogen tanks

　　 1. Placement of liquid nitrogen tank

　　 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 its inherent characteristics, liquid nitrogen tanks are not allowed to be tilted, placed horizontally, inverted, stacked, collide with each other or collide with other objects, no matter when they are used or stored. upright.

　　 2. Cleaning of liquid nitrogen tank

　　 When the liquid nitrogen tank is not in use, rinse it with clean water, drain the water, blow it dry with a blower, and place it at room temperature for later use. After the liquid nitrogen in the liquid nitrogen tank is volatilized, the remaining missing substances (such as frozen sperm) quickly melt and become liquid substances attached to the inner tank, which will corrode the aluminum alloy inner tank. If a cavity is formed, the liquid The nitrogen tank must be scrapped, so it is necessary to scrub the tank after the liquid nitrogen in the liquid nitrogen tank is exhausted. The specific scrubbing method is as follows: first take out the lifting cylinder in the liquid nitrogen tank, remove the liquid nitrogen, and leave it for 2-3 days. After the temperature in the tank rises to about 0°C, pour in warm water of about 30°C and scrub with a cloth. If you find that some melted substances stick to the bottom of the inner tank, you must carefully wash it off. Then rinse it with clean water several times, then turn the liquid nitrogen tank upside down, place it indoors where it is not safe to tip over, air dry it naturally, or use a blower as described above. Note that during the entire scrubbing process, the action should be light and slow, the temperature of the poured water should not exceed 40℃, and the total weight should not exceed 2kg
