• Due to the large heat of the container, the first time the liquid is filled, the heat balance time is longer, and it can be pre-cooled with a small amount of liquid medium (about 20% of the total capacity), and then slowly filled (so that it is not easy to form an ice block) .
• In order to reduce the loss during filling in the future, please refill the liquid when there is still a small amount of liquid in the container. Or fill the liquid within 48 hours after using the liquid.
• In order to ensure the safe and reliable use of the container, the container can only be filled with liquid nitrogen, liquid oxygen and liquid argon.
• When infusion, water and frost on the outer surface of the container are normal.
• When transporting liquid media on roads of Class 3 or below, the speed of the car should not exceed 30km/h.
• The vacuum nozzle cover on the container, the seal of the safety valve, and the seal can not be damaged.
• If the container is not used for a long time, drain and dry the liquid medium inside the container, then close all valve seals.
• Before filling the liquid medium, the container must be dried with dry air to dry the container liner and all the valves and pipes before it can be filled with liquid medium. Otherwise, the pipe will be blocked by ice, which will affect the pressure rise and infusion.

This equipment belongs to the instrument and meter category. It should be handled gently when using it. When opening each valve, the force should be moderate and the speed should not be too fast; especially when the metal hose is connected with the joint at the inlet/drain valve. Can not be tightened too much with force, so as not to twist or even twist the joint, hold the valve body with one hand when screwing.
