Product description

Compact Globe Scientific GHS-550 hotplates & magnetic stirrers with 1000W heating, PID control, and up to 20L stirring capacity.

The Globe Scientific GHS-550 Series comprises advanced laboratory hotplates and magnetic stirrers engineered for precise heating and mixing in biotechnology and molecular diagnostics research. These units feature a durable 7-inch chemical-resistant glass ceramic surface optimized for easy cleanup and extended service life, ideal for bioprocessing and synthetic biology workflows.

Key technical specifications include:

  • Heating power: Robust 1000-watt heaters supporting temperatures up to 550°C, with overheating protection at 580°C.
  • Temperature control: Microprocessor and PID-controlled circuits (GHS-550HSP model) ensure accurate thermal regulation within ±0.2°C, critical for molecular cloning and live-cell assay preparation.
  • Display & Interface: The GHS-550HSP model includes an LCD display for precise monitoring of speed and temperature plus an RS232 port enabling remote control, data logging, and PC integration—useful in automated biomanufacturing environments. Other models provide easy-to-read LED displays and intuitive analog controls for streamlined operation.
  • Stirring capabilities: Maintenance-free brushless DC motors deliver strong magnetic coupling for reliable mixing of volumes up to 10L (GHS-550HS, GHS-550S) or 20L (GHS-550HSP), ensuring solution homogeneity essential in cell imaging and fluorescence analysis. Stirring speed ranges from 0 to 1500 rpm with standard 80mm stir bars.
  • Design: Compact, low-profile footprint conserves valuable benchtop space in biotechnology labs and clinical diagnostics facilities. The glass ceramic surface is resistant to chemical damage, supporting demanding research environments.

These hotplates and magnetic stirrers are widely adopted in synthetic biology research and biopharmaceutical production pipelines, supporting workflows such as gene editing reagent preparation and molecular diagnostics sample processing. Optional PT1000 external temperature sensors and retort stands are available for direct vessel temperature measurement, enhancing process control and repeatability.

Overall, the GHS-550 series delivers reliable thermal and stirring performance tailored for advanced laboratory applications in biotechnology, biomedical engineering, and clinical research.

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.
