Precautions for the use of liquid nitrogen tanks
In cell culture or other experiments, it is often necessary to preserve cells or tissues in liquid nitrogen for subsequent experiments. Inappropriate use of liquid nitrogen tanks often leads to damage to the human body and loss of cell samples. Pay attention to the following items during use:
    1. Because the heat of the liquid nitrogen tank is large, the first time the liquid is filled with nitrogen, the heat balance time is longer, and it can be pre-cooled (about 60L) with a small amount of liquid nitrogen medium, and then slowly filled (so that it is not easy to form ice plug).
    2. In order to reduce the loss of liquid nitrogen in the future, please refill the liquid nitrogen when there is a small amount of liquid nitrogen in the liquid nitrogen tank. Or fill the liquid within 48 hours after using the liquid nitrogen.
    3. In order to ensure the safety and reliability of the liquid nitrogen tank, the liquid nitrogen tank can only be filled with liquid nitrogen, liquid oxygen and liquid argon.
 
Precautions for the use of liquid nitrogen tanks
    4. When infusion, water and frost on the outer surface of the liquid nitrogen tank is a normal phenomenon. When the pressure increasing valve of the liquid nitrogen tank is opened for boosting operation, since the pressurized coil is attached to the inner wall of the outer cylinder of the liquid nitrogen tank, the liquid nitrogen tank coil is absorbed by the liquid nitrogen. The heat of the cylinder is vaporized to achieve the purpose of boosting, and there may be spotted frost on the outer cylinder of the liquid nitrogen tank. After closing the liquid nitrogen tank booster valve, the frost point will slowly dissipate. When the liquid nitrogen tank pressure increasing valve is closed and the infusion operation is not performed, the outer surface of the liquid nitrogen tank has water and frost, which indicates that the vacuum of the liquid nitrogen tank has been destroyed, and the liquid nitrogen tank cannot be used any more. Should be looking for professional manufacturers of liquid nitrogen tanks for repair or disposal.
 
Precautions for the use of liquid nitrogen tanks
    5. When transporting liquid nitrogen medium on the road surface of Grade III or below, please do not exceed 30km/h.
    6. The vacuum nozzle on the liquid nitrogen tank, the seal of the safety valve, the seal can not be damaged.
    7. If the liquid nitrogen tank is not used for a long time, drain the liquid nitrogen medium inside the liquid nitrogen tank and blow it dry, then close all valve seals.
    8. Before filling the liquid nitrogen medium, the liquid nitrogen tank must be dried with dry air to dry the container liner and all the valves and pipes before it can be filled with liquid nitrogen medium. Otherwise, the pipeline will be blocked by ice, which will affect the boosting and infusion.
    9. Liquid nitrogen tanks are instruments and meters. When using them, they should be handled gently. When opening the valves of liquid nitrogen tanks, the force should be moderate and the speed should not be too fast; especially the liquid nitrogen tank metal hose and / When the joint at the drain valve is connected, it cannot be overtightened with a strong force. It can be sealed by slightly tightening it in place (the ball head structure is easy to seal), so as to avoid twisting or even twisting the liquid nitrogen tank nozzle. Hold the liquid nitrogen tank with one hand.
    10. It is not possible to replace the special can lid with other plugs, and it is even more difficult to use a sealed plug to prevent the liquid nitrogen from continuously evaporating, and the nitrogen pressure formed is increased to cause damage to the container.
