Self pressurized liquid nitrogen tank, also known as liquid nitrogen supply tank, can be used for liquid supplement and turnover transportation of biological containers such as liquid nitrogen, liquid oxygen, liquid argon, etc., and also suitable for supporting devices of experimental instruments and electronic instruments. The products meet the national standard GB / t16774-2012. In order to ensure high-quality vacuum layer, the unique patented technology of evacuation and multilayer insulation technology are adopted, and the adsorbent is treated by biochemical treatment.

Advantages of self pressurized liquid nitrogen tank:

1. Unique tank support, good tank stability;

KF can be selected according to the need of evaporation;

3. Double safety valve structure to ensure the safety of products;

4. All stainless steel 304 material production, high strength container;

5. All welds were detected by helium mass spectrometer;

Technical parameters of self pressurized liquid nitrogen tank

During the process of infusion and infusion in the self pressurized liquid nitrogen tank, it is suggested that:

1. Infusion, generally speaking, is from the liquid nitrogen tank to output liquid, first close the vent valve, and then open the booster valve. At this moment, carefully observe the pressure gauge. When the indication is 0.05Mpa, please open the drain valve to realize continuous infusion;

2. Liquid inlet means filling liquid nitrogen into the tank. First open the vent valve, connect the infusion metal hose and the inlet / outlet valve interface, open the inlet / outlet valve, fill liquid nitrogen from the inlet / outlet valve, and close the inlet / outlet valve after filling liquid nitrogen.

Attention to the operation of storage and transportation valves of self pressurized liquid nitrogen tank:

1. If the tank is used to store biological samples or components that need to be frozen, the inlet / outlet valve and booster valve should be closed first. Remember that the vent valve must be opened;

2. If low temperature medium is required for transportation in this tank, the operation of each valve is the same as the storage function. At the same time, pay attention to that the base circle of the container can not be directly placed on the transport vehicle, and the cushion at the bottom of the packing box should be placed under the base ring. It is better to add a wooden box and fix it on the vehicle with ropes.
