Product description

Precision ThermoFlex chillers offer 900W or 1400W cooling with ±0.1°C stability for fluid temperature control from 5°C to 90°C.

The Thermo Scientific NESLAB ThermoFlex 900 and 1400 series are advanced *recirculating chillers* designed for reliable external temperature management of laboratory instruments, analytical systems, and process equipment demanding stable fluid circulation. Both models utilize a robust microprocessor-controlled interface and maintain a consistent temperature stability of ±0.1°C, essential for applications in biotechnology, molecular diagnostics, and bioprocessing workflows that require precise thermal regulation.

Key technical features include:

  • Reservoir Volume: 1.9 gallons polyethylene tank ensuring sufficient fluid capacity for continuous operation
  • Cooling Capacity:
  • ThermoFlex 900: 900W at 60Hz, suitable for standard cooling applications between 5°C and 40°C
  • ThermoFlex 1400: Enhanced 1400W cooling at 60Hz, capable of maintaining fluid temperatures from 5°C up to 90°C, providing extended versatility for biomanufacturing and synthetic biology experiments
  • Pump Capacity: Up to 4.0 gpm at 60 psig, delivering consistent fluid flow rates necessary for accurate temperature control in live-cell imaging and fluorescence analysis setups
  • Physical Dimensions: Compact footprint (26 x 14 x 27 inches) optimized for benchtop or floor-adjacent laboratory layouts
  • Power Requirements: 115V, 50/60Hz with current ratings of 11A (900 model) and 14.1A (1400 model)

Both ThermoFlex models incorporate serviceable filters and continuous fluid circulation technology, ensuring maintenance ease and extended unit longevity. The ThermoFlex 900 is ideal for routine external cooling within moderate temperature ranges, while the ThermoFlex 1400 is engineered to support applications that demand higher cooling capacities and expanded temperature control, making it critical in pharmaceutical temperature-sensitive processes and synthetic biology research that involves thermal cycling.

Widely adopted in laboratories focused on molecular biology, clinical diagnostics, and biomedical engineering, these chillers support stable operation of sensitive analytical instruments and bioprocess equipment, making them indispensable for biotechnology laboratories requiring seamless integration with thermal management systems.

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.
