High-torque Watson Marlow 730 peristaltic pump with 0.1–360 rpm speed range for precise sterile fluid transfer.
The Watson Marlow 730 peristaltic pump is engineered for precise flow control and contamination-free fluid handling in demanding bioprocessing, chemical transfer, and production workflows. It features a digital variable speed drive capable of 0.1 to 360 rpm with fine 0.1 rpm increments and a high control ratio of 3600:1, allowing accurate and repeatable dosing or continuous fluid transfer critical in molecular diagnostics and synthetic biology applications.
Key technical specifications include:
The Watson Marlow 730 supports wide tubing compatibility and multiple pumphead configurations, optimizing flow rates and tubing lifespan for biomanufacturing and pharmaceutical production pipelines. The model variants range from standalone units to versions with Fieldbus automated control capabilities (730DuN), enabling seamless integration with PLC and SCADA systems to automate and scale workflows from R&D through to pilot and commercial production.
Designed to prevent product contamination by limiting fluid contact strictly to tubing, this peristaltic pump is essential for applications requiring sterile processing, including live-cell imaging preparations, gene editing reagent formulation, and clinical diagnostic sample handling. Its industrial-grade sealing and long-term reliability make it a preferred choice for laboratories and facilities standardizing on Watson Marlow tubing systems and seeking robust pumps capable of evolving automation demands without replacement.
This pump is widely used in biotechnology research, bioprocess engineering, and molecular biology laboratories, supporting critical operations that demand repeatability, chemical compatibility, and minimal cross-contamination risk in bioprocess workflows.
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.
