Product description

Watson Marlow 620Di peristaltic pump enabling accurate fluid transfer, ideal for bioprocessing and molecular biology workflows.

The Watson Marlow 620Di Peristaltic Pump is a reliable laboratory pump designed for precise and contamination-free fluid handling. Featuring a robust rotary pump head with a compact footprint, it delivers accurate and gentle pumping action suitable for sensitive biotechnology applications such as bioprocessing, molecular diagnostics, and synthetic biology.

  • Model 620Di offers digital control with variable speed adjustment, ensuring optimal flow rates tailored for diverse laboratory protocols.
  • Its peristaltic mechanism guarantees fluid isolation within disposable tubing, maintaining sterility essential for cell culture and gene editing workflows.
  • Widely adopted in biopharmaceutical production pipelines, this pump supports continuous and intermittent fluid transfer with high reproducibility.
  • Compatible with a broad range of tubing materials, facilitating use in applications involving viscous fluids, shear-sensitive biomaterials, or sterile media transfer.
  • The pump’s design supports clean-in-place (CIP) and sterilize-in-place (SIP) procedures, crucial for maintaining contamination control in clinical diagnostics and biomanufacturing environments.

This pump is an essential piece of equipment for researchers requiring precise, contamination-free pumping for live-cell imaging preparation, fluorescence analysis sample handling, and other critical life sciences protocols. Its integration into workflows supports enhanced reproducibility and process control in biotech research and industrial applications.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
