VACUUBRAND Diaphragm pump ME 1 20721000

The ME 1 diaphragm pump (20721000) is an oil-free, single-stage laboratory vacuum pump designed for vacuum filtration, sample preparation and modest vacuum applications in chemistry, microbiology and analytical processes. It provides compact, low-vibration operation with a top-mounted power switch and PTFE-wetted parts for chemical resistance. Typical use cases include single-port filtrations and continuous, water-free evacuation of gases and vapors.

Key Features:

• Model: ME 1, Article number: 20721000
• Max. pumping speed (50 Hz): 0.7 m³/h
• Ultimate vacuum: 100 mbar (≈75 torr)
• Inlet connection: Hose nozzle DN 6–10 mm; Outlet: Silencer / G1/8"
• Rated motor power: 0.04 kW; Rated speed 1500/1800 min⁻¹ (50/60 Hz)
• Dimensions (L×B×H): 270 × 121 × 155 mm; Weight: 5.4 kg
• Noise level: 49 dBA (50 Hz)

Advantages:

• Oil-free operation avoids water use and contaminated wastewater, making it suitable for routine laboratory filtrations.
• PTFE diaphragm and valves deliver high chemical resistance for work with aqueous media and aggressive chemicals (chemistry version available).
• Whisper-quiet, low-vibration, space-saving design with top-mounted power switch for convenient benchtop use.
• Maintenance-free drive system and a proven long diaphragm service life (typically 15,000 operating hours) reduce downtime and servicing.
