VACUUBRAND MD 4C VARIO Select Chemistry Diaphragm Pump is a high-performance vacuum solution designed specifically for demanding laboratory applications. This intelligent pump features the advanced VACUU-SELECT vacuum controller with a graphical interface and pre-programmed lab applications, streamlining workflows and reducing hands-on time. Ideal for processes involving high boiling solvents, the MD 4C VARIO Select automatically detects boiling points and adjusts the vacuum to optimize evaporation speed and protect samples.
Key Features:
- Ultimate vacuum of 1.5 mbar (1.1 Torr) for reliable handling of high boiling point solvents
- Maximum pumping speed: 2.7 CFM at 60Hz (4.6 m³/h at 50Hz)
- Four-head, three-stage design ensures robust, stable vacuum performance
- VACUU-SELECT controller with touch-screen interface, manual or fully automated operation, and simple drag-and-drop programming
- Automatic boiling point detection and real-time vacuum adjustments to prevent bumping and foaming
- VARIO motor control minimizes noise (43 dBA) and extends service life of diaphragms
- Exceptional diaphragm lifespan significantly reduces maintenance costs
- Ethernet, USB, and RS-232 interfaces for easy integration with lab systems
- Compact, lightweight footprint to maximize bench space
Typical Applications
Ideal for rotary evaporation, vacuum distillation, concentration, drying processes, and any application requiring precise, adaptive vacuum control. The system is also highly effective in laboratory vacuum networks where it automatically provides optimal pumping speeds and vacuum levels without manual adjustments.
