• VRP1

    KNF Neuberger's new vacuum controller is constructed of corrosion-resistant Kalrez® and polypropylene materials and allows precise control of vacuum levels and hysteresis needed for your procedure. Especially useful for rotary evaporators, vacuum ovens and distillation systems. The microprocessor has memory for five vacuum settings for multiple extraction processes. Controller can be used with any diaphragm style vacuum pump such as Cole-Palmer, Sargent, Vac-O-Brand, and KNF Neuberger. It is designed to eliminate continuous running of the pump which reduces noise levels and saves energy. Either ton or mbar can be selected as the unit of measure. Instant venting or purging is achieved with the press of a button. The controller has bright red LED digits on the display, 3/8" I.D. hose connections, weight of 3 lbs. (1.4 kg), dimensions of 7.6" D x 5.5" W x 2.75" H (3 cm x 2.1 cm x 1 cm), and 115 VAC 60 Hz. Vacuum range is 2 to 276 torr (2 to 103 mbar) with an accuracy of ±0.3% FSO.
