Product description

Microprocessor-controlled 89L circulating water bath with ±0.05°C uniformity, 5–99.9°C range, ideal for enzyme and serology applications.

The Thermo Precision 2868 Circulating Water Bath is a high-precision, microprocessor-controlled immersion circulator designed for advanced laboratory and biotechnological applications. Featuring an 89-liter (23-gallon) capacity and stainless steel construction, it provides uniform temperature control critical in molecular diagnostics, enzyme kinetics, and quality control workflows.

  • Temperature range: Ambient +5°C to 99.9°C, adjustable in 0.1°C increments
  • Temperature uniformity: ±0.05°C at 37°C crucial for reproducible serology and biochemical assays
  • Control system: Microprocessor-based with digital display and 5 push button interface
  • Circulation: Water flow around the perimeter enhanced by an elevated sample platform ensures homogenous heat distribution essential in live-cell imaging and biomanufacturing applications
  • Safety: Over-temperature protection with high limit thermostat prevents heater runaway
  • Dimensions: Interior 36″ x 18″ x 9.5″; Exterior 45″ x 20″ x 12″; Weight 85 lbs
  • Power: 120V, 50/60Hz with stainless steel gable cover and diffuser shelf included

This circulating water bath supports critical bioprocessing and synthetic biology protocols by maintaining stable temperature environments for sensitive biological samples. Widely adopted in clinical diagnostics and biochemical research, it is essential for workflows demanding precise thermal regulation. The durable epoxy-polyester exterior and corrosion-resistant interior tub allow use with distilled water or ethylene glycol solutions, expanding its applications in biotechnology and biomedical engineering.

Ideal for molecular biology researchers and laboratory professionals, the Thermo Precision 2868 ensures consistent results in temperature-dependent experiments including nucleic acid amplification, enzyme activity assays, and protein denaturation studies.

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.
