MD 12C VARIO selectVARIO® chemistry pump
Overview
- VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory
- automatic boiling point detection and adjustment of the vacuum for short process times
- meets high vacuum requirements for large quantities of most high boiling solvents
- extraordinary diaphragm life for minimum operational and servicing costs
- #
Ultimate vacuum
1.5 mbar
Ultimate vacuum with gas ballast
3 mbar
Max. pumping speed 50 Hz
15 m3/h
VARIO® chemistry pump in action
The MD 12C VARIO select pump is an excellent solution for those who need high pumping speed and are working with high boiling point solvents. Combined with the reliability born of its chemical resistant fluoropolymer and perfluoroelastomer wetted materials, this pump delivers reliable performance for floor-standing rotary evaporators, vacuum drying ovens, vacuum distillation columns, and other similar applications. The integrated VACUU·SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process to maintain process control. With VARIO control, the pump runs only as fast is necessary. This extends the maintenance intervals and makes the pumping unit whisper quiet. #
