Product description

Digital hotplate stirrer with ceramic-coated 20L top plate, PID control, 30–350°C, 2000 rpm for precise biotech workflows

The TS-18QG digital hotplate stirrer features a 20L capacity with a square 180 x 180 mm ceramic-coated aluminum top plate, offering excellent corrosion resistance and durability. It employs a heater-integrated structure for efficient heat transfer with a maximum temperature of 350°C (662°F), controlled via precise PID feedback in modes including optimal, fast, slow, and user-defined.

Stirring is powered by a brushless DC (BLDC) motor, ensuring spark-free operation for enhanced safety in sensitive laboratory environments. Stirring speeds range from 30 to 2000 rpm, supporting magnetic stir bars up to 40 x 8 mm, suitable for bioprocessing and synthetic biology applications requiring reliable mixing and temperature control.

Key features include:

  • B class PT100 temperature probe (max 250°C) with error display for accurate temperature monitoring
  • Temperature auto-tuning and calibration for reproducible experiment conditions
  • Spill-proof design and multiple over-temperature prevention devices enhance operational safety
  • Optional accessories such as clamp rod mounting and removable transparent shield for versatile experimental setups
  • Built-in countdown timer up to 99 hours 59 minutes for extended processes
  • Body constructed from powder-coated aluminum alloy with a compact footprint (209 x 326 x 102 mm) and weight of 3.8 kg

This hotplate stirrer is essential for molecular diagnostics, biomanufacturing, and live-cell imaging workflows where controlled mixing and heating are critical. Its compatibility with various research domains in biotechnology, including gene editing and synthetic biology labs, makes it a highly useful tool for laboratories prioritizing precise temperature and stirring control.

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.
