The liquid nitrogen tank 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, the liquid nitrogen tank is not allowed to be tilted, placed horizontally, inverted, stacked, or collided no matter when it is used or stored.

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 is scrapped.


The specific scrubbing method is as follows:

1. 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 warm water of about 30°C and wipe it with a cloth.

2. Rinse several times with clean water, then turn the liquid nitrogen tank upside down, place it indoors where it is not safe to tip over, and let it air dry.

Note: During the whole scrubbing process, the action should be light and slow, the temperature of pouring water should not exceed 40℃, and the total weight should not exceed 2kg.


Safe transportation of liquid nitrogen tanks

The liquid nitrogen tank must be cushioned and fixed in a wooden frame during transportation. Filling should be used to separate the tank from the tank to prevent bumps and bumps and prevent dumping. When loading and unloading the truck, it is necessary to prevent the liquid nitrogen tank from colliding, and not to drag it on the ground at will, so as not to reduce the service life of the liquid nitrogen tank.
