Integrated vacuum regulator VACUU·SELECT

Overview

• Supplied complete and ready for use, including integrated solenoid isolation valve, non-return valve and standard hose connections
• Predefined vacuum applications and automatic boiling-point detection save operator time
• Simple in-line installation between pump and vacuum application; vacuum measurement is located in the valve block
• Integrated venting valve allows inert-gas purge or controlled venting
• Integrated check valve minimizes interaction with other applications on the same vacuum supply

Product description
The VACUU·SELECT complete controller is a two‑point vacuum regulator designed to increase process efficiency for laboratory and technical applications supplied by existing vacuum sources (individual pumps or VACUU·LAN networks). Available as benchtop, rack/stativ or built-in versions for lab casework, the integrated unit combines the VACUU·SELECT vacuum controller, a ceramic diaphragm vacuum sensor, a chemical‑resistant solenoid isolation valve, a non‑return valve and a venting valve. The intuitive, application‑based user interface offers manual set‑point control, predefined vacuum processes and the ability to create custom programs with drag‑and‑drop editing. For solvent evaporation the controller automatically detects the boiling pressure and holds the pressure stable using two‑point control.
