Compact HPLC valve drive for versatile lab applications.
Valves play an essential role in all HPLC applications. Primarily, 2-position valves serve injection purposes, but they can also support complex switching systems. Meanwhile, multi-position valves enable functions like fraction collection, eluent selection, or column switching. The Knauer Smartline S6 Valve Drive stands out due to its compact dimensions, requiring minimal bench space, making it ideal for laboratories. When multiple valves are necessary, this unit offers a practical solution by allowing combination into one stackable device. It features a 7-port/1-channel switching valve that can seamlessly switch across six positions, with each command resulting in a precise 60° rotation, completing a full cycle back to the starting position on the sixth switch. The valve head is constructed from durable PEEK material, ensuring reliable performance.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
