          Liquid Nitrogen Container Of Safety Knowledge
          1. The container can only be filled with liquid nitrogen. Do not load other low temperature media. In particular, can not be filled with liquid oxygen, so as not to the container itself with the structure of the flammable substances caused by the explosion.
          2. The container should be placed in a cool, dry place, the room should be well ventilated to avoid excessive nitrogen in the air caused by suffocation. Do not close the heat source and do not put things on top of the container.
          3. Take the mouth with a repeatable suction structure, please do not start the user to avoid affecting the cold performance.
          4. Liquid nitrogen temperature of -196 ℃, the operation should be protective measures. Such as Dai leather, cotton gloves and so on. Do not bare your hands. Prevent liquid nitrogen splash, hit the skin or eyes caused by frostbite.
          5. Can only use the matching cork, not with other non-qualified products instead. Otherwise, it will affect the performance of the container, even if the liquid nitrogen continues to evaporate to form a compressed air pressure, resulting in damage to the container.
          6. Liquid level check: with a wooden foot into the bottom of the container center, about 10 to 15 seconds after the removal of its frost length is the liquid level. Do not use hollow tube inspection, to prevent liquid nitrogen from the tube spray wounding. The lowest level of liquid can not be lower than the highest surface of cold objects, to ensure that liquid nitrogen will flooded. When the liquid nitrogen to the cold storage will be exposed to the liquid surface, it should be timely liquid nitrogen.
