Laboratory vacuum pump MD 12C NT VARIO® select

diaphragm

Overview

• VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies laboratory workflows
• automatic boiling point detection and adaptive vacuum control for shorter process times
• suitable for handling large quantities of most high-boiling solvents
• long diaphragm life reduces operating and maintenance costs

Product description
The MD 12C NT VARIO select is a chemically resistant diaphragm vacuum pump designed for laboratory applications that require high pumping speed and reliable operation with aggressive or corrosive media. The pump uses fluoropolymer wetted materials and perfluoroelastomer diaphragms. Integrated VACUU·SELECT control provides application-based operation: manual set-point control, fully automated distillations, or custom processes via drag-and-drop. For solvent evaporation the controller continuously detects boiling and automatically adjusts the vacuum. VARIO speed control adapts pump speed to the actual gas load to extend maintenance intervals and reduce noise.
