The most advanced vacuum control is the VARIO® control for chemistry diaphragm pumps, in which vacuum is precisely controlled by continuously 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.optional remote control
