Product Description

ChemStar Dry pumps quickly down to the working pressures for most evaporative operations (10 to 0.8 torr). It is in this range that ChemStar Dry creates maximum flow for clean, fast, and thorough high performance evaporation. There is no oil, and the system automatically maintains and protects itself for repeatable robust performance.
