Liquid nitrogen tanks are vacuum containers. In addition to static storage, they can also be used for transportation when filled with liquid nitrogen. How to take liquid nitrogen out of a liquid nitrogen tank? If it is a small liquid nitrogen tank, pour it out directly, but be careful about the splashing of liquid nitrogen. A liquid nitrogen pump or self-pressurized liquid nitrogen tank can also be used to take out liquid nitrogen.

How to take liquid nitrogen out of a liquid nitrogen container?

1. Directly pour out liquid nitrogen

Generally, for small liquid nitrogen tanks, the liquid nitrogen can be poured directly, but when using this method, be careful not to splash liquid nitrogen onto the skin and cause frostbite. Large liquid nitrogen tanks are difficult to operate by one person, and liquid nitrogen needs to be pressed out with the help of a pressure device (liquid nitrogen pump).

2. Liquid nitrogen pump

Close the liquid nitrogen pump outlet valve and rotate it clockwise until it is tightened. Insert the liquid nitrogen pump into the liquid nitrogen tank so that the sealing ring seals the liquid nitrogen pump and the neck tube of the container. If a foot pump is used, just step on the pump directly, and the liquid nitrogen can flow out.

3. Through a self-pressurized liquid nitrogen tank

Principle: Use a small amount of liquid nitrogen in the tank to vaporize and generate pressure, so that the container can automatically discharge liquid nitrogen, thereby replenishing liquid nitrogen for other containers.

Liquid nitrogen tank, also known as liquid nitrogen biological container, is a biological storage container, usually used to store active biological materials, such as livestock and poultry semen, active vaccines, etc.
