How to calculate the daily evaporation of liquid nitrogen?
A lot of customers are using it liquid nitrogen tank One of the most important concerns is, liquid nitrogen tank How long can the liquid nitrogen be stored in the tank? In addition to daily opening the liquid nitrogen tank to take liquid nitrogen or take the stored biological samples, part of liquid nitrogen will be volatilized during these back and forth operations. The following is about how much liquid nitrogen can be evaporated every day and the test and calculation method of static liquid nitrogen daily evaporation I hope it can help you. If you don't know how to calculate, you are advised to consult the technicians of bander liquid nitrogen tank directly.

The static liquid nitrogen storage period of the product was measured by weighing method

The test should be carried out under the condition of ambient temperature of 20 ± 30 ℃ and atmospheric pressure. Meanwhile, the test can not be conducted in a directly ventilated site.

In the test, the container should be filled with liquid nitrogen of more than 1 / 2 of the container, standing for 48 hours, the first weighing (a) g, the first weighing after 3 days to get (b) g, the evaporation capacity Q is calculated according to the following formula

Q = A-B / 3 (g / D)

If it is necessary to express it in volume (liter), it can be converted by the following formula:

D = q / 808 (L / D)
