***New innovation in vacuum*** Welch 2070B-01 chemstar dry pump is new innovation in vacuum allows a chemical duty, dry vacuum pump to achieve 50 mTorr (0.050 Torr). This is the perfect, dry, oil free solution the vacuum user has been waiting for. The Welch 2070 performs superior on Schlenk lines (Vacuum manifold), Rotary evaporators (can strip DMSO), freeze dryers and much more. The powerful 150 liters per minute allows the 2070 to run multiple application volumes simultaneously.

Using an oil-free dry PFTE high vacuum pump will preserve the purity of your samples, eliminate the need to cold trap and eliminate oil changes. Please contact your Chemtech Scientific vacuum expert to discuss eliminating hydrocarbon contamination from oil sealed vacuum pumps in your lab.
