How to pour liquid nitrogen into a liquid nitrogen container

When pouring liquid nitrogen into a  liquid nitrogen container, you can choose whether to use a funnel as an aid according to the size of the container. Care must be taken when filling liquid nitrogen.The small container can directly pour liquid nitrogen into the container. If there is a liquid nitrogen pump, the liquid nitrogen can be directly connected to the liquid nitrogen tank to pour liquid nitrogen.

Attention: 

1.The liquid nitrogen container should be pre-cooled first to prevent the inner tank from being damaged too quickly and reduce the service life.

2.When the liquid nitrogen tank is dumped, workers should try to wear protective clothing to avoid liquid nitrogen burns.

3.When filling liquid nitrogen, do not pour liquid nitrogen on the vacuum exhaust port, otherwise the vacuum will be reduced.
