The Welch ChemStar 2071B-01 Vacuum Pump is engineered to perform under aggressive chemical environments where standard pumps fail. Featuring a corrosion-resistant wetted path and a two-stage, oil-sealed rotary vane design, this pump achieves deep vacuum levels below 1 x 10⁻⁴ Torr, while withstanding exposure to corrosive vapors and condensates.
Designed for demanding applications such as rotary evaporation, freeze drying, distillation, and solvent recovery, the ChemStar 2071B-01 is a trusted choice for pharmaceutical, industrial, and academic laboratories.
Its integrated gas ballast system helps minimize condensation within the pump, extending oil life and reducing maintenance. Built on Welch’s proven DuoSeal technology, the 2071B-01 offers both performance and longevity in tough chemical conditions.
