Product description

Recirculating chiller with -25°C to 150°C range, 15 LPM pump, ±0.01°C stability for precise temperature control.

The Thermo Neslab RTE 7 is a refrigerated bath circulator designed for high-performance temperature control in laboratory environments. It features a wide temperature range of -25°C to 150°C, supporting both open containers and closed-loop fluid recirculation systems, making it essential for biotechnology applications such as molecular diagnostics and bioprocessing workflows.

Key technical specifications include:

  • Temperature stability of ±0.01°C ensuring precise thermal regulation critical in live-cell imaging and synthetic biology research
  • Industrial-grade pump delivering 15 LPM (4 GPM) with a maximum pump head of 16 feet (4.9 m), enabling efficient fluid flow over extended distances in biomanufacturing and laboratory cooling circuits
  • Cooling capacity of 500 watts at 20°C combined with an 800-watt heater for reliable thermal cycling
  • R134a refrigerant optimized for stable refrigeration and environmental compliance
  • Compact bath volume of 7.2 liters (1.9 gallons), suitable for integration with various laboratory setups
  • Digital microprocessor control with settable high/low temperature alarms and fault detection for enhanced operational safety

This unit is widely used in clinical diagnostics, laboratory temperature control systems, and bioprocess engineering where precise fluid temperature regulation enhances experimental reproducibility and equipment reliability. The Neslab RTE 7 recirculating chiller is compatible with bath volumes like the RTE 17 series but designed specifically to maximize efficiency in smaller-scale applications.

Its robust build and precise temperature management make it a staple in biotechnology laboratories involved in gene editing experiments, biopharmaceutical production pipelines, and temperature-sensitive assay development. The device supports critical workflows requiring stable temperature environments, such as protein purification, enzymatic reactions, and cell culture temperature maintenance.

Overall, the Thermo Neslab RTE 7 combines reliable pump performance, broad temperature coverage, and advanced microprocessor controls, positioning it as an indispensable instrument for scientists and researchers demanding stable, reproducible temperature control in both research and industrial biotechnology settings.

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.
