The Watson-Marlow 504U Mk2 is a precision peristaltic pump engineered for accurate dosing, dispensing, and fluid transfer in laboratory, industrial, and bioprocess environments. Its design ensures fluid contact is confined to the tubing, enhancing chemical compatibility, sterility, and simplifying maintenance—features critical for synthetic biology, molecular diagnostics, and biopharmaceutical production pipelines.
Key technical features include:
The Watson-Marlow 504U Mk2 peristaltic pump is widely adopted in biotechnology and clinical diagnostics for its reliability in fluid handling tasks, making it an indispensable instrument in research fields such as gene editing, live-cell imaging sample preparation, and synthetic biology research labs focused on bioprocess optimization.
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.
