High-precision Watson Marlow 503S peristaltic pump delivering up to 160 rpm for sterile fluid transfer in biotechnology.
The Watson Marlow 503S peristaltic pump is engineered for precise and contamination-free liquid transfer in biotechnology and life science laboratories. Featuring a lockable button design, this pump ensures secure operation during the delivery of sterile culture media, buffers, and solutions critical in molecular diagnostics and bioprocessing workflows. Key technical specifications include:
This peristaltic pump is widely adopted in synthetic biology research and biopharmaceutical production pipelines where contamination risk must be minimized. Its capacity for both small and large volume delivery makes it essential for gene editing experiments, cell culture media preparation, and other biomanufacturing processes requiring sterile and accurate fluid handling. The compact footprint and technical reliability make the Watson Marlow 503S an effective tool for live-cell imaging support and fluorescence analysis protocols in clinical diagnostics and biotechnology laboratories.
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.
