Liquid nitrogen tank? It is a highly vacuum freezer. How can the service life of liquid nitrogen tanks be extended during the use of liquid nitrogen tanks?

1. Before using the liquid nitrogen tank, a small amount of liquid nitrogen should be injected to pre-cool it. When the tank temperature reaches the liquid nitrogen temperature, liquid nitrogen is filled until it is full. Always check the neck plug and neck plug ditch at any time to remove the icing on the neck plug, plastic material can not be placed on the neck plug to ensure the use of liquid nitrogen cans function.

2. The liquid nitrogen tank should be gently handled to prevent collision and squeezing. When moving, it must not be dragged on the ground and it must be lifted. Store in a dry, well-ventilated room at all times to prevent it from getting wet.

3. The liquid nitrogen tank should minimize the number of times of transportation and opening. If it needs to be transported, it must be fixed on the trunk with a rope and keep it upright. Be careful not to knock, overturn or lie horizontally to prevent violent vibration.
