Welch ChemStar Dry - Oil Free Deep Vacuum System
Eliminate messy oil maintenance, the threat of oil contamination to your
sample, and cold trapping in many applications. Handle even high chemical
vapor loads for simple, efficient deep vacuum. ChemStar Dry excels where no
dry vacuum pump has before ? the first practical alternative to oil-seal
rotary vane pumps.
ChemStar Dry automates High Performance vapor flow (to 150L/min) at working
vacuum levels (0.08 to 10 torr). Chemical resistant, max. vacuum is 0.05 torr.

remove condensable vapors between runs for repeatable top performance and
extended diaphragm life.
