Welch MPC 301 E diaphragm vacuum pump for oil-free laboratory vacuum, with PTFE wetted parts and 2.3 to 2.5 m³/h displacement.
The Welch MPC 301 E diaphragm vacuum pump is a chemical-duty laboratory vacuum pump for vacuum filtration, rotary evaporation, degassing and solvent removal. It is also used for sample preparation in life sciences laboratories.
The pump uses a single-stage, direct-drive configuration with PTFE and fluoropolymer wetted parts. Its hose nozzle inlet and exhaust connections are noted with a possible DN8 or KF interface.
The unit is used equipment. The power requirement is 230 V AC at 50/60 Hz.
The Welch MPC 301 E is a chemical-duty diaphragm vacuum pump for laboratory vacuum applications. It produces an oil-free vacuum and uses PTFE and fluoropolymer wetted parts for chemical resistance.
The pump is offered as used equipment.
PTFE and fluoropolymer wetted parts support vacuum work involving aggressive vapors and solvents. The oil-free design avoids introducing pump oil into the vacuum path, which suits filtration, evaporation and solvent removal applications where contamination control matters.
The free air displacement of approximately 2.3 to 2.5 m³/h and ultimate vacuum below 75 mbar correspond to the listed vacuum filtration, rotary evaporation, degassing and solvent removal applications.
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.
