Rotary evaporator vacuum pump ME 16C NT VARIO select

laboratorydiaphragmoil-free

Overview

• VACUU·SELECT vacuum controller with graphical UI and predefined applications to simplify lab workflows
• Automatic boiling point detection and continuous vacuum adjustment for shorter process times
• Designed for evaporation of large volumes of low‑boiling solvents
• PTFE sandwich diaphragm and fluoroplastic pump heads for extended maintenance intervals

Product description
The ME 16C NT VARIO select is a single‑stage, oil‑free chemistry diaphragm pump for continuous pumping of corrosive gases and vapors. It combines a high pumping speed with an ultimate vacuum of 70 mbar, making it well suited to solvent evaporation tasks. Pump heads are made from chemically resistant fluoroplastics and the diaphragm is a proven PTFE sandwich design, resulting in long service intervals. The integrated VACUU·SELECT controller provides an application‑based graphical interface with predefined processes, manual set‑point control and the option to create custom sequences. During solvent evaporation the controller continuously detects the boiling point and automatically adjusts the vacuum. VARIO speed control runs the pump only as fast as required, reducing noise and extending maintenance intervals.
