Henan Tianchi Cryogenic Machinery Manufacturing Co., Ltd. is a modern enterprise with advanced technology for producing liquid nitrogen biological containers. The products produced are widely used in animal husbandry and breeding livestock semen frozen storage; medical industry, such as human organs, skin, blood, cell freezing Preservation; bioengineering, industrial cooling assembly, cold treatment of metal materials, cryogenic crushing, superconductivity, etc.

Notice:

1. The first time When filling the liquid , It's better to filled with a small amount of liquid nitrogen to pre-cool, and then slowly filled.

2. In order to reduce the loss during filling, please fill the container when there is a small amount of liquid in the container. If the liquid is used up, please fill it within 48 hours.

3. In order to ensure the safe and reliable use of the container, this container can only be filled with liquid nitrogen; during infusion, ice and frost on the outer surface of the container are normal.

4. The protective cover of the vacuum nozzle on the container, the seal of the safety valve, and the lead seal should not be damaged; if the container is not used for a long time, drain the liquid medium inside the container and blow dry, then close all the valves and seal it.

5. Liquid nitrogen is a low temperature liquid of -196 degrees, which can not be transported by express and sold as empty container.

6. The phenomenon of ice blockage occurs at the pressurized coil and sometimes at the drain

The solution is to first fill the container with nitrogen from the nitrogen bottle, raise the pressure inside the container to between 0.05MPa-0.09MPa, and drain the liquid medium inside the container; then use dry hot air to block the pipes with ice Perform blow-off.
