1. Before use, you need to carefully check the appearance to see if there is any dent or damage, and whether the vacuum exhaust port is intact. These inspections are to ensure that the thermal insulation performance of the liquid nitrogen tank is good.
2. Liquid nitrogen tanks rely on liquid nitrogen to ensure deep and low-temperature storage, so the tanks can only be filled with liquid nitrogen. Mixing other flammable substances can easily cause interaction and cause an explosion.
3. The liquid nitrogen tank container should be placed in a cool, dry place to ensure good indoor ventilation.
4. The temperature of liquid nitrogen is -196°C. Self-protection measures should be taken when extracting and storing the freezing rack, such as wearing leather or cotton gloves. Be cautious when operating with bare hands. At the same time, it is necessary to prevent liquid nitrogen from splashing, which may cause frostbite when it touches the skin and other parts.
