The Watson-Marlow 520U is a digitally controlled peristaltic pump featuring an enclosed pump head designed for accurate and contamination-free fluid transfer, essential in laboratory and bioprocessing environments. Operating on 100-240 VAC at 50/60 Hz, this pump supports a wide range of voltage standards for global lab use. The digital interface ensures precise flow rate adjustments, making it ideal for applications such as molecular diagnostics, synthetic biology, and biomanufacturing workflows.
This pump is critical for molecular biology researchers and biomedical engineers seeking reliable, pulse-free pumping in live-cell imaging platforms and fluorescence analysis systems. Its robustness and versatility support complex bioprocessing and synthetic biology research environments.
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.
