MD 12C VARIO select
VACUUBRAND20743750ca. 450 mmca. 260 mmca. 25.5 kgThe 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.
