These dry vacuum pumps, designed to meet chemical duty laboratory needs, are ideal for rotary evaporation, concentrators, evaporators, vacuum ovens, filtration, degassing, and other chemical applications

Pumps feature flows to 70L/min and ultimate vacuum levels down to 2torr. No cold traps are needed to operate. These stand-alone vacuum pumps need very little maintenance, leading to low cost of ownership and improved productivity.

Pumps feature built-in advanced vapor management (AVM) for precise control capability of the distillation of organic solvents and applications handling aggressive vapors and gases.

Certifications: The 115V pumps are CSA certified. The 230V pumps are CE marked.

Ordering information: The 115V pumps are supplied with a North American plug. The 230V pumps are supplied with a Continental European (Schuko) plug with IEC cord. For application-specific ordering recommendations, see the datasheet "How to Select a DryFast Vacuum Pump."
