2. Buy Liquid Nitrogen Contact, Master Zhao: 18363060110.
3. After purchasing liquid nitrogen, pay attention to whether the hexagonal screw on the top of the liquid nitrogen tank is tightened. Otherwise, the liquid nitrogen runs out and the holiday needs to be bought again.
4. Close the pressure reducing valve when you fill the liquid nitrogen. After the liquid nitrogen is filled, you must open the pressure reducing valve slightly to prevent the liquid nitrogen vaporization from increasing the pressure in the tank and cause safety accidents.
5. When filling liquid nitrogen, pay attention to the short silicone tube exhaust on the nuclear magnetic exhaust pipe.
6. After the completion of liquid nitrogen infusion, the silicone tube connected to the inlet and outlet of the silicone tube and the nuclear magnetic liquid nitrogen should first be softened with a blowing blower, then the silicone tube should be removed to prevent the silicone tube from cracking. Rinse the condensation from the exhaust air and put on the lid to prevent condensed water from entering the tank and freezing the lid.
