Compared with compressed industrial gas cylinders, Dewar bottles or dewar flask can hold a large amount of gas under relatively low pressure.

Convenient operation of cryogenic liquid source.

Dual output, one output nitrogen gas, one output liquid nitrogen. The equipment provides mortgage refrigeration liquid-liquid nitrogen, so it can be used in gas-liquid two-phase.

The self-pressurizedCryogenic liquid nitrogen tank is made of stainless steel, and the whole container is a booster system, which realizes the function of continuous liquid discharge by vaporizing the liquid. Therefore, the self-pressurizing liquid nitrogen tank is used for liquid nitrogen, liquid oxygen, and liquid argon. The main equipment for liquid replenishment and turnover transportation of biological liquid nitrogen containers.

Liquid feeding method:

1: Intake liquid from the inlet/discharge valve, like a container filled with liquid, and start to empty the valve. The metal hose for infusion is connected to the inlet/discharge valve, and the inlet/discharge valve is opened to open the inlet/discharge valve. Fill the valve with liquid medium, after filling the liquid, close the inlet/discharge valve.

2: Inject liquid from the screw plug of the liquid inlet. When filling the container with liquid, first open the vent valve, unscrew the screw plug of the liquid inlet, and add liquid medium from the liquid inlet. After the liquid is filled, the screw plug Just screw into the liquid inlet.

Infusion:

1: Close the vent valve.

2: Open the booster valve.

3: Observe the pressure gauge.

4: When the pressure rises to 0.05Mpa, open the drain valve to start continuous infusion.

Precautions:

1: When filling the liquid for the first time, the thermal equilibrium time is relatively long, a small amount of liquid is required for pre-cooling work, and then the filling work is performed slowly, so as to avoid ice blocking.

2: If the container is not used for a long time, dry the liquid medium inside the container, then close all valves and seal it.

3: Before the container is filled with liquid medium, dry air is required to dry the container, valve, and pipe before it can be filled with liquid medium, otherwise it will cause ice blockage.
