Product description

Industrial-grade Thermo Neslab Merlin M150 recirculating chiller with 5–35°C range, 5045W cooling, ideal for biotech and medical labs.

The Thermo Neslab Merlin M150 Recirculating Chiller delivers precise temperature control with a wide operating range from 5°C to 35°C, making it suitable for critical applications in biotechnology, molecular diagnostics, and medical research. Featuring an industrial-grade positive displacement pump capable of 3.0 gpm at 60 psi (11.4 lpm at 4.2 bar), it ensures stable and efficient fluid circulation essential for bioprocessing workflows and live-cell imaging cooling requirements.

Key specifications include:

  • Cooling Capacity: 5045 W (17219 BTU), supports high-demand thermal management
  • Reservoir Volume: 0.5 gallons (1.8 liters) with quick-draining functionality for easy maintenance
  • Flow Rate: Maximum 5.5 liters/minute suitable for diverse laboratory setups
  • Compressor: 1/3 hp with CFC-free refrigeration system, aligning with environmental safety standards
  • Electrical Requirements: 200-230V, 50/60 Hz power supply, requiring dedicated 20A breaker
  • Dimensions: 28 x 21 x 36 inches, compact footprint optimizes limited laboratory bench space
  • Weight: 254 lbs ensuring stable installation

The unit is equipped with audible alarms and adjustable temperature limits to prevent overheating or overcooling, essential features for critical biomanufacturing and synthetic biology processes sensitive to temperature fluctuations. Additional design elements, such as isolation valves, prevent fluid overflow during vertical pumping, enhancing operational safety.

Widely adopted in clinical diagnostics and biotechnology research labs, the Thermo Neslab M150 chiller offers robust, reliable thermal regulation. Its compact design and stable performance make it a preferred solution for molecular cloning workflows, fluorescence analysis cooling, and biopharmaceutical production pipelines where precise temperature control is critical.

Included accessories are inlet/outlet tubing, a user manual, and a 230V power cord, backed by a 30-day warranty, ensuring immediate deployment in laboratory environments.

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.
