Specifications Additional Info Famous DurabilityDeep Vacuum to 10-4 torrLow RPM for cooler operationAddress a wide variety of laboratory vacuum needs with these rugged oil-seal pumps. Use DuoSeal vacuum pumps for Schlenk drying manifolds, freeze drying, vacuum ovens, glove boxes, degassing, concentrations, distillations, and more.DuoSeal pumps are built to rigorous quality standards with precisely machined components. The belt-driven design produces low pump rpm operation, reducing 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 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). DuoSeal single stage pumps provide economical vacuum to 0.015 torr.See Additional Info tab for model selection to find the best DuoSeal pump to suit your application needs.Thomas No.Displacement L/min.
