Static Evaporation Rates for Liquid Nitrogen Storage in Cryogenic Freezers

Evaporation rates are not shown in Chart’s marketing brochures, although, for each series of cryogenic freezers there is a general list of static evaporation rates. Static evaporation rates are approximations only. The tank would have to be untouched for a freezer to be static. Since the liquid nitrogen freezers are always used in non-static conditions these figures can only be taken as estimates. Evaporation rates can be changed significantly by a variety of uncontrolled parameters. Below is a list of rates for liquid nitrogen storage.

It is important to use the best equipment available for things like this. I work in a lab in South Dakota. We previously were using a different company's cryogenic equipment which did not work out so well. We then switched to PrincetonCryo and the equipment was better suited for our lab!
