Description
Vacuubrand ME 2S Oil-Free Diaphragm Vacuum Pump 120V 60Hz 2.2 m³/h 100 mbar
The Vacuubrand ME 2S is a compact, oil-free diaphragm vacuum pump designed for clean, contamination-free vacuum generation in laboratory and light industrial environments. Operating on 120V/60Hz single-phase power, it produces an ultimate vacuum of 100 mbar with a maximum pumping speed of 2.2 m³/h, making it well suited to routine lab vacuum tasks without the maintenance demands of oil-sealed rotary vane pumps. The unit is manufactured in Germany by VACUUBRAND GmbH+Co KG to high quality standards and bears CE certification.

Applications
Diaphragm vacuum pumps like the Vacuubrand ME 2S are standard equipment in chemistry, biology, and analytical laboratories where a clean, oil-free vacuum source is required. They are widely used to support rotary evaporators (rotovaps) for solvent removal, Büchner funnel filtration, solid-phase extraction (SPE), vacuum desiccation, and general aspiration tasks. Because they are oil-free, these pumps do not contaminate samples with pump oil vapors and require far less routine maintenance than oil-sealed rotary vane alternatives — an important advantage in cleanroom-adjacent or sensitive analytical work. The ME 2S is particularly common in university research labs, pharmaceutical QC labs, and chemical processing environments. With an ultimate vacuum of 100 mbar, it is appropriate for general-purpose lab vacuum applications, though it is not intended for high-vacuum or molecular vacuum work.
This Vacuubrand ME 2S Oil-Free Diaphragm Vacuum Pump has been visually inspected and appears to be in good used condition overall. The housing, motor, and cooling fins are clean with no cracks or significant damage. The inlet and outlet port fittings show white mineral/crystalline deposits from prior use — this is typical for pumps used in filtration or evaporation applications and is visible in our photos. The on/off switch, power cord, and NEMA plug are intact. The pump was pulled from a working laboratory environment.
