Product description

Digital PID-controlled 20L unit-type water bath with ±0.1°C stability for precise temperature control in laboratories.

The Thomas Scientific T-N22 Unit-Type Temperature-Controlled Circulating Water Bath offers precise thermal control ideal for biotechnology workflows including molecular diagnostics and bioprocessing applications. Key technical features include:

  • Capacity: 20 liters with an effective inner tank size of 400×350×150 mm.
  • Temperature Control: Digital PID controller enabling a temperature range from room temperature +5°C up to +60°C, with a maximum of 80°C when using a lid (not included). Temperature stability is maintained within ±0.1°C, critical for consistent experimental conditions in cell culture and biochemical assays.
  • Heating: Equipped with a 1 kW sheath wire heater (2 × 500W elements) providing uniform heat distribution.
  • Agitation: Jet flow stirring system ensures homogenous temperature distribution and sample mixing for even incubation conditions.
  • Safety Features: Includes power fuse, over-temperature cutoff, and dry heating prevention to protect samples and equipment.
  • Materials: Inner tank constructed from corrosion-resistant stainless steel SUS-304, ideal for maintaining chemical integrity during biomanufacturing processes. Exterior finish is painted steel sheet for durability.
  • Electrical: Operates on standard AC 100V, 10A with 50/60 Hz compatibility and a 2-meter power cord.
  • Dimensions and Weight: Overall footprint of 520×390×320 mm, weighing approximately 13 kg, offering a compact and sturdy solution for laboratory benchtops.

This water bath is widely used in life science research, clinical diagnostics, and biotechnological applications requiring reliable temperature-controlled incubation, essential for molecular cloning, gene editing experiments, and synthetic biology research.

*Note*: This unit is used and sold as-is; original accessories like the lid and cart are not included. Performance and functionality may vary compared to new models.

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.
