Laboratory vacuum pump PC 3012 NT VARIO select DUO

double-diaphragmoil-free

VACUU·SELECT vacuum controller with graphical user interface and predefined applications easy to integrate via digital or analogue interfaces automatic boiling point detection and adjustment of the vacuum for short process times meets high vacuum requirements for very large quantities of most high boiling solvents extraordinary diaphragm life for minimum operational and servicing costs excellent environmental compatibility through low energy consumption, no operating fluid needs (oil, water) and efficient solvent recovery VARIO® chemistry pumping unit in action The VARIO® DUO pumping units are consisting of a combination of two individual VARIO® pumping units, connected in parallel on the suction side and driven synchronously by one vacuum controller VACUU·SELECT. The vacuum is controlled accurately. The speed of the two individual pumps is exactly adjusted to the vacuum needs. The controller allows both fully automatic distillations without any user pre-settings as well as specific and reproducible program sequences. The integration into existing control systems via digital and analog interfaces is also possible. The consequent design to highest chemical resistance provides the ideal prerequisite for universal use in chemistry and pharmacy - without any operating fluid such as water or oil. The unique combination of high chemical resistance, very good ultimate vacuum and high pumping speed with low energy consumption and without any operating fluid makes the new VARIO® DUO pumping units the contemporary vacuum source for many applications in the range of kilo-lab, pilot and small productions.
