Sorption pump

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 ultimate pressure is about 10−2 mbar. With special techniques this can be lowered till 10−7 mbar. The main advantages are the absence of oil or other contaminants, low…
