Welch ChemStar Dry - Oil-Free Deep Vacuum System 2070

Eliminate cold-trapping, messy oil maintenance, and the threat of oil contamination to your sample. 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.
