The laboratory liquid nitrogen tank itself has a double-walled vacuum structure. The addition of thermal insulation adsorption materials can achieve the function of isolating external heat and absorbing low temperatures, ensuring that there is always a low-temperature cycle in the tank. External heat cannot enter and internal low temperatures cannot escape. But it is a liquid nitrogen container, which needs to contain liquid nitrogen and samples. It is unrealistic to be completely airtight, so an opening is left. To prevent heat from pouring in from the mouth of the jar, a neck plug is installed.

Therefore, you will find that the liquid nitrogen tanks used in the laboratory have a plug, which is the neck plug mentioned above. It "blocks" the mouth of the tank and functions like the plug of a thermos. It is an important means of isolating heat transfer. component.

The role of this part of the design in keeping the jar warm is self-evident.

The effect is very prominent, and it also causes users to pay too much attention to it, and even cause misunderstandings!

A more common problem is that the loose plug design leads to poor sealing and will affect the cells!

But it won’t!

All liquid nitrogen tank neck plugs are designed to be loose!

This design is to prevent the volatilized nitrogen from being exhausted and accumulating pressure in the liquid nitrogen tank. When the tank cannot withstand it, it will explode. A bursting tank is dangerous, as is the liquid nitrogen that flows out. Because the natural evaporation of liquid nitrogen is inevitable, it is necessary to leave an exhaust port and loosen the neck plug.

Moreover, users don’t have to worry. This small gap will not affect the overall thermal insulation of the liquid nitrogen container at all, causing large temperature fluctuations and increasing the daily evaporation loss of liquid nitrogen. Large temperature fluctuations will only occur when you forget to replenish liquid nitrogen, or when the liquid nitrogen does not completely immerse the cells!
