KNF SC 920G Laboratory Vacuum Pump Sysytem
Speed Regulated, Faster Processing

KNF SC 920 vacuum pump system features powerful pumping speeds and a 1.5 Torr end vacuum for shorter processing time with a wide range of solvents.

Because the pumping speed is completely adjustable, flask sizes up to 20L can be accommodated. The precision sensing system prevents bumping and maintains consistency for all vessel sizes.

This new system combines KNF’s latest diaphragm pump technology with a smart microprocessor control and an efficient motor, saving you time, building energy, and money while protecting the environment.

The remote control for SC vacuum pump systems
The remote control comes with a touchscreen and a control knob, providing up to 12 hours of battery life. Wireless range: about 50 m without obstacles / about 10 m through walls.
