Quiet, compact, oil-free pump for aggressive gases and vapors. Ideal for lab use.
The KNF Laboport N 820.3 FT.18 Diaphragm Vacuum Pump is engineered for optimal performance in laboratory settings, providing a maximum flow rate of 20 liters per minute and achieving a final vacuum of up to 8 mbar absolute. The pump operates under a pressure of up to 1 bar relative, while maintaining permissible fluid temperatures between 5 and 40°C. Its components, including a PTFE-coated diaphragm and PTFE pump head, ensure exceptional chemical resistance, making it ideal for handling extremely aggressive or corrosive gases and vapors.

For users unsure of their requirements, KNF provides a comprehensive guide to their laboratory vacuum pumps, including access to downloadable resources on selecting the ideal diaphragm pump for varied 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.
