Vacuubrand VARIO pumps

"Best diaphragm pump in the world. No down time in 14 years. Effective and economical system."

Description

 

The most advanced vacuum control is the VARIO® control for chemistry diaphragm pumps, in which vacuum is precisely controlled by continuosly adapting the pumping speed to the system demands. VARIO® chemistry pumping units from VACUUBRAND make it possible to automatically find the vapor pressure and adapt the vacuum to the process without keying in any parameters. VARIO® control instantaneously and precisely adjusts the volume flow rate to the changing process conditions, resulting in high evaporation rates and shorter process times. This unique control approaches boiling points gently to prevent overpumping and foaming, for sample protection and optimum solvent recovery.

Performance features:

• automatic adaptation of the vacuum level throughout the process for high process reproducibility and unattended operation, short process times due to zero-fluctuation (hysteresis-free) vacuum control, even for large amounts of vapor
• whisper quiet and ultra low vibration
• excellent environmental friendliness due to efficient solvent recovery
• intuitive operation with turn-and-tap jog wheel and clear text menus, with integrated venting valve
