The compact Model 1640 vacuum controller regulates the vacuum level of your application precisely, conveniently, and without using precious bench space

The intuitive, corrosion resistant design incorporates a numeric keypad, PTFE solenoid valve, and solid state cramic sensor for precise/ reproducible vacuum control. Features dual setpoints, timer, memory, and repeat functions.

The Model 1640 controller stores up to 5 programmed methods, establishing up to 2 vacuum level setpoints and durations for each method. Convenient keypad enables rapid manual vacuum level adjustment.

The Model 1640 Vacuum Controller is rack mountable and easy to set up. Works with direct or belt-drive vacuum pumps up to 100 L/min, diaphragm pumps, WOB-L® piston pumps, water aspirators, and house vacuum systems.

Vacuum level can be regulated from 2 Torr to atmospheric pressure, ±1 Torr. Use Model 1640 for fine control of rotary evaporation, vacuum ovens and chambers, and other common laboratory vacuum processes.
