Electric High-Vacuum Pumps
Achieve powerful vacuum and continuous flow for applications such as vacuum drying, solvent evaporation, and distillation. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow.

Use these pumps in applications such as degassing and servicing refrigeration and freezer systems. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow.

Electric Ultra-High-Vacuum Pumps
Achieve vacuum levels up to 1 x 10 -12 torr with these ultra-high-vacuum pumps. Each unit includes two pumps—a diaphragm pump and a turbomolecular pump—that work together to create extremely high levels of vacuum in your chamber. Units are compact, so they fit on top of a workbench or table.
Pumps are ready to use as soon as they’re plugged in and connected to a chamber. Since they don’t use oil, they won’t introduce contaminants into your system. They hardly vibrate, minimizing interference with sensitive instruments and measurement devices.
Pumps with claw-clamp intake connections require a ring and four double-claw clamps (all sold separately) to connect to other components. Claw-clamp connections are also known as ISO-K fittings. These pumps include a gauge with quick-clamp connections, which requires a quick clamp and a ring (both sold separately) to connect. Quick-clamp connections are also known as KF fittings.
Pumps with flanged intake connections and the included gauge each require a gasket (sold separately) to connect to your chamber. Flanged connections are also known as CF fittings.
