Use these rugged oil-seal pumps for a wide range of laboratory vacuum needs

Durable by design, DUOSEAL® pumps are built with precisely machined components to rigorous quality standards. Low pump rpm operation reduces friction, oil temperature, and oil degradation to extend maintenance intervals and pump life. Large oil reservoir minimizes contaminant effects to maintain high vacuum performance. Use of a cold trap is recommended to protect the pump and enhance vacuum levels. Do not operate continuously at pressures greater than 10 torr.

DUOSEAL® vacuum pump applications include Schlenk drying manifolds, freeze drying, vacuum ovens, glove boxes, degassing, concentrations, distillations, and more. DUOSEAL® two stage pumps provide deep vacuum (1 X 10-4 torr) at pumping speeds ranging from 25 to 650 L/min (0.9 to 23 CFM).
