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.
| Model | SER (L/day) Model |
| MVE 103 | 4.1 |
| MVE 205 | 3.0 |
| MVE 510 | 6.2 |
| MVE 616 & C | 8.5 |
| MVE 808 | 8.0 |
| MVE 1223 | 13.0 |
| MVE 1318 | 8.5 |
| MVE 1426 & C | 14.0 |
| MVE 1839 | 13.0 |
| 800 series | 5.0 |
| 1500 series | 7.5 |
| 1800 series | 12.5 |
| 1842 (old 1830) | 12.0 |
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!
