Laboratory pump ME 1C

suctionelectricdiaphragm

Overview

• Top-mounted power switch for convenient, quick operation
• Whisper-quiet operation with very low vibration (≈49 dBA at 50 Hz)
• Compact footprint for minimal benchtop space
• Maintenance-free drive system and long diaphragm lifetime
• Chemically resistant PTFE diaphragms and valves

Description
The ME 1C is a compact, oil-free chemistry diaphragm pump designed for vacuum filtration and single-sample laboratory workflows. It provides a space-saving, easy-to-operate solution for sample preparation in chemistry, microbiology, wastewater monitoring and other analytical processes. Key design elements include the top-mounted power switch, PTFE diaphragms and valves for chemical resistance, and a maintenance-free drive system that extends diaphragm service life. An optional manual vacuum regulator valve with dial gauge enables stepless adjustment of pumping speed and ultimate vacuum.

Applications

• Vacuum filtration (single-station setups)
• Solid phase extraction and general sample preparation in chemistry and microbiology
• Wastewater control and other analytical laboratory processes
