EnglishDefinition
The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen; the typical molecular sieve used is a synthetic zeolite.
Examples
- 1. A sorption pump is usually constructed in stainless steel, aluminium or borosilicate glass.
