VACUUBRAND Chemistry diaphragm pump ME 1C 20721100

The ME 1C chemistry diaphragm pump (model ME 1C, part number 20721100) is a one-stage, oil-free laboratory vacuum pump designed for chemical-resistant applications such as vacuum filtration and solid phase extraction. It provides compact, quiet operation with chemically resistant PTFE diaphragms and valves, delivering a final vacuum of 100 mbar for routine sample preparation in chemistry, microbiology and analytical workflows. The pump is intended for continuous, oil-free pumping of gases and vapors where moderate vacuum is required and can be fitted with an optional manual vacuum regulator with dial gauge to adjust pumping speed and ultimate vacuum.

Key Features:

• Model: ME 1C
• Part number: 20721100
• Max. pumping speed (50 Hz): 0.7 m³/h
• Ultimate vacuum: 100 mbar (≈75 Torr)
• Inlet/outlet connection: Hose nozzle DN 8–10 mm
• Rated motor power: 0.04 kW; motor speed 1500/1800 min⁻¹ (50/60 Hz)
• Dimensions (L×B×H): 270 × 121 × 154 mm; Weight: 5.4 kg

Advantages:

• Oil-free operation eliminates consumption of water and production of contaminated wastewater during routine use.
• PTFE diaphragms and valves provide high chemical resistance suitable for solvent and aqueous filtrations.
• Compact, low-noise design with top-mounted power switch saves benchtop space and enables quiet lab operation.
• Long diaphragm service life and maintenance-free drive reduce downtime and spare-part frequency.
