Welch™ Programmable Vacuum Controller

Description

Designed to automatically regulate the applications vacuum level precisely, conviniently and without using precious bench space

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

• Intuitive, corrosion resistant design incorporates a numeric keypad, PTFE solenoid valve, and solid state ceramic sensor for precise/reproducible vacuum control
• Dual set points, timer, memory, and repeat functions
• Stores up to 5 programmed methods, establishing up to 2 vacuum level set points and durations for each method
• Convenient keypad enables rapid manual vacuum level adjustment
• 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

Rotary evaporations, centrifugal evaporations, vacuum ovens
