Product description

Bioprocess rotator shaker providing precise 30 rpm circular and rocking motion with adjustable timer for lab mixing.

The Lab-Line 4631 Rotator Shaker is a compact, lightweight benchtop mixer designed specifically for bioprocessing, serological assays, and laboratory mixing applications. Operating at a fixed speed of 30 revolutions per minute, it delivers smooth circular and rocking motion with a 10-degree tilt, minimizing shear stress to preserve sample integrity during mixing.

Key technical features include:

  • Three-dimensional rocking combined with circular motion for uniform sample mixing essential in molecular diagnostics and bioprocessing workflows
  • Adjustable timer ranging from 1 to 60 minutes, enabling precise control for time-sensitive laboratory protocols
  • Platform dimensions of 6.75 in x 5 in (17 cm x 13 cm), suitable for small-volume sample tubes and serological plates
  • Operational flexibility between continuous mixing and timed intervals, supporting diverse applications such as synthetic biology and gene editing experiments
  • Electrical specifications: 120V, 60Hz power supply ensuring compatibility with standard lab infrastructure

Weighing only 2.72 kg (6.0 lbs), the shaker’s compact form factor allows easy integration into crowded lab benches and biomanufacturing environments. This refurbished unit is delivered fully functional and turnkey ready but does not include computer or software interfaces.

This laboratory rotator shaker is widely used in biotechnology for bioprocessing mixers and is critical in biopharmaceutical production pipelines where gentle and controlled mixing affects downstream molecular biology protocols. Its precise and consistent mixing capabilities make it an essential device for researchers working in cell culture, live-cell imaging preparation, and fluorescence analysis.

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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
