Tested KR2i KrosFlo research TFF system, fully functional and ready for use; configuration is incomplete.
The Spectrum Labs KR2i KrosFlo Research Tangential Flow Filtration (TFF) System is a laboratory-scale bioprocessing instrument for membrane-based concentration and diafiltration workflows. It is suitable for research applications in biotechnology, biopharmaceutical development, molecular biology, and cell and gene therapy process development.
This research TFF system can support laboratory-scale bioprocessing workflows where controlled membrane filtration is required. The incomplete status should be considered when evaluating compatibility with existing pumps, filter holders, tubing assemblies, and process equipment.
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.
