Two-stage rotary vane vacuum pump with 6 m³/h pumping speed, 2×10⁻³ mbar ultimate vacuum, suited for mass spectrometry labs.
The Pfeiffer Vacuum DUO 5 M is a professionally refurbished two-stage rotary vane vacuum pump offering a pumping speed of 6 m³/h (3.5 CFM) and an ultimate vacuum level of 2×10⁻³ mbar. Engineered for high performance in laboratory vacuum applications and mass spectrometry, its compact design (435 x 160 x 215 mm) ensures convenient integration into benchtop setups and systems with space constraints.
Key technical features include:
This pump is essential for molecular diagnostics, bioprocessing laboratories, and synthetic biology workflows where reliable vacuum generation is critical. Its ability to provide a stable low vacuum environment makes it widely adopted in biotechnology research, gene editing platforms, and biomanufacturing processes that require precise control of vacuum conditions.
Ideal for enhancing the performance of mass spectrometers, freeze dryers, and vacuum filtration systems, the DUO 5 M supports advanced applications in biomedical engineering and cell imaging by ensuring consistent vacuum pressure essential for sensitive analytical techniques. The pump is supplied with a user manual facilitating straightforward installation and operation.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
