Product description

Edwards E1M18 oil-sealed vacuum pump delivers up to 25 m³/h airflow, 3x10⁻² mbar ultimate vacuum for lab and industrial use.

The Edwards E1M18 vacuum pump is a robust oil-sealed sliding vane pump engineered for reliable vacuum generation in laboratory and industrial settings. Featuring a direct drive, single-stage mechanism, it supports essential applications including gas analysis, leak detection, electron microscopy, and cryogenics—critical in advanced molecular diagnostics and bioprocessing workflows.

Key technical specifications include:

  • Flow rate: 20.5 to 25.0 m³/h (12.1 to 14.7 ft³/min) at 50/60 Hz
  • Motor speed: 1,440/1,720 RPM
  • Ultimate vacuum: Down to 3 × 10⁻² mbar (without gas purge)
  • Motor power: 0.55 kW / 0.75 kW with integrated cooling fan
  • Inlet/outlet: NW25 inlet, 15 mm removable nozzle outlet
  • Operating temperature range: 13 to 40°C
  • Noise level: 57 dB(A) at 50 Hz
  • Oil capacity: 0.9 to 1.4 liters (Ultragrade 19 recommended)
  • Thermal overload protection with automatic reset to enhance operational safety

Weighing approximately 43.54 kg (96 lbs), the E1M18 is compact and free-standing, suitable for integration into biotechnology labs specializing in synthetic biology and molecular cloning, where stable vacuum conditions are essential. This pump is widely adopted in biopharmaceutical production pipelines and clinical diagnostics, providing consistent vacuum pressure critical for downstream processes.

Note: The tested unit currently achieves a minimum vacuum of 6 mbar, slightly above manufacturer specifications, indicating that servicing or oil replacement may be necessary to restore full efficiency.

This vacuum pump is harmonized under code 841410, signifying its classification within vacuum pump equipment essential for biotech and biomedical engineering applications requiring reliable vacuum generation.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
