Product description

Digital microplate shaker with 3mm orbit, 100–1000 RPM speed, ideal for ELISA and immunoassays in biotechnology.

The Thomas Scientific Microplate Shaker (Model 980235) is a microprocessor-controlled orbital shaker designed for secure and precise agitation of up to four standard microplates or deep-well blocks simultaneously, making it essential for molecular diagnostics and immunoassay workflows. Its 3 mm orbit size and speed range of 100 to 1000 RPM with ±2% accuracy enable gentle and consistent mixing, critical in bioprocessing, live-cell assay preparation, and biopharmaceutical production pipelines.

Key features include:

  • Digital front-panel controls with slow ramping speed to safely reach the programmed set point, enhancing protocol reproducibility in synthetic biology and gene editing research
  • An integrated elapsed timer supporting timed or continuous operation for customizable agitation cycles
  • A platform dimension of 19.7 x 27.9 cm (7¾ x 11 inches) equipped with retaining spring clips to firmly hold microplates during shaking, ideal for fluorescence analysis and cell imaging applications
  • Compact dimensions of 17 x 11 x 4 inches, weighing 17 lbs, powered by standard 120V, 50/60 Hz electrical supply consuming only 25W

This shaker is widely adopted in biotechnology laboratories for applications requiring uniform orbital shaking such as ELISA development, nucleic acid extraction protocols, and biomanufacturing quality control. The device has been rigorously tested and meets all manufacturer specifications, ensuring reliable performance essential in clinical diagnostics and biomedical engineering research environments. The unit includes a 30-day warranty and a 120V power cord, supporting immediate integration into laboratory workflows.

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.
