Robust filtration unit, ideal for biomolecule processes and scalable applications.
This listing is for a single Cytiva CSUH 040 Feed Retentate unit, which is in full working condition and ready for immediate use. Designed for optimum performance and product recovery, the Centramate™ TFF cassette holders are part of Cytiva's filtration portfolio and available in various sizes to meet diverse application requirements. These holders facilitate efficient concentration, purification, and buffer exchange of biomolecules, making them perfect for small batch production, process development, and Phase I clinical studies. The unit ensures precise linear scale-up to larger process systems with identical fluid path lengths.

The system is available in 316L Stainless Steel for robust, high-performance applications, and Ultra-High Molecular Weight Polyethylene (PE) for a more economical yet durable alternative. A variety of membrane types and screen options offer system versatility and application-specific 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.
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.
