Product description

Magnetic hot plate stirrer with PID control, 140mm ceramic top, 350°C max temp, 50–2000 rpm speed, ideal for bioprocessing labs.

The Fisherbrand Isotemp RT Magnetic Hot Plate Stirrer offers precise temperature and stirring control essential for molecular diagnostics and bioprocessing workflows. Featuring a round 140 mm ceramic-coated aluminum alloy top plate, it ensures efficient heat transfer, excellent temperature uniformity, and robust corrosion resistance suitable for biotechnology and synthetic biology applications.

  • Temperature range: Up to 350°C (662°F) with microprocessor PID control for stable thermal regulation.
  • Stirring speed: Adjustable from 50 to 2000 rpm with smooth-start operation and feedback control to maintain speed consistency despite changes in sample viscosity.
  • Capacity: Supports sample loads up to 25 kg and has a stirring capacity of 20 liters of water, accommodating a wide range of laboratory vessel sizes.
  • Safety features: Includes a hot-top warning indicator and automatic over-temperature shutoff to ensure user protection during prolonged biomanufacturing processes.
  • Additional features: Two threaded support rod ports for accessory mounting, a detachable 120V, 5A power cord, and compact dimensions (7 x 12 x 4 inches, 7 lbs) for convenient benchtop use.

Widely adopted in biotechnology research and clinical diagnostics, this magnetic hot plate stirrer is critical for live-cell imaging preparation, fluorescence analysis sample processing, and synthetic biology experiments requiring precise mixing and heating. Its digital controls and robust build quality make it reliable for demanding applications in molecular cloning workflows and biopharmaceutical production pipelines.

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.
