Liquid Nitrogen Supplementation In Liquid Nitrogen Container

When the amount of liquid nitrogen in the liquid nitrogen container is left, do you need to replenish liquid nitrogen? Someone asked if the liquid nitrogen is used up and then added?

Answer: The liquid nitrogen in the liquid nitrogen container can not be used up. In general, the amount of liquid nitrogen in the liquid nitrogen container should be replenished when it is used up to 1/3, because this time in the liquid nitrogen container There is not much liquid nitrogen, and the temperature difference between the bottom end and the top of the liquid nitrogen container is particularly large. Therefore, liquid nitrogen should be replenished in time to avoid damage to biological samples stored in liquid nitrogen containers.
