Peristaltic pump with 3-roller pumphead, 0–350 rpm speed, supports variable tube bores for precise fluid flow control.
The Watson Marlow 505Di Peristaltic Pump features an integrated 313D flip-top pumphead with a 3-roller design, enabling fast and error-free tube loading critical for fluid transfer accuracy. Speed ranges from *0 to 350 rpm*, supporting a broad range of flow rates tailored for multiple tube bore sizes:
This compact pump measures 120 x 220 x 340 mm (HxWxD) and weighs 6.6 kg, making it suitable for laboratory benchtops and bioprocessing environments. Its precise fluid control and versatility in tubing size make it essential for molecular diagnostics, biopharmaceutical production pipelines, synthetic biology workflows, and cell culture media transfer applications. The 505Di is widely adopted in biotechnology and molecular biology research for continuous and intermittent fluid delivery requirements, providing consistent flow rates critical for biomanufacturing and gene editing protocols.
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.
