Product description

Recirculating chiller with PID control, ±0.5°C stability, and centrifugal pump for precise laboratory cooling.

The Julabo FL601 is a compact recirculating chiller designed for precise external temperature control in laboratory cooling applications. Featuring microprocessor-based PID temperature control with ±0.5°C stability, it effectively adjusts cooling output via a centrifugal pressure pump according to the connected system's thermal load. This unit is compatible with a range of coolant fluids including water, water/glycol mixtures, and silicone fluids, making it versatile for various biotech environments such as bioprocessing, molecular diagnostics, and synthetic biology workflows.

Key technical features include:

  • Integrated stainless steel bath tank for corrosion resistance and durability
  • Top-fill access, filling level indicator, overflow port, and front drain for straightforward fluid management
  • Splash-proof membrane keypad with bright LED display for intuitive front-panel operation
  • RS232 interface and potential-free alarm output for seamless integration with laboratory automation and external monitoring systems
  • Refrigerant used is R404A, charged at 300 g, supporting efficient thermal regulation under up to 28 bar pressure ratings (both PS HP and PS LP)
  • Dimensions: 18 x 13 x 25 inches; Weight: 105 lbs; Electrical: 115V, 60Hz, 10A power supply

The FL601’s no-side-vent layout supports flexible placement on or under laboratory benches, while low liquid level protection includes optical and audible alarms to prevent system faults. This makes it essential for biomanufacturing pipelines and critical cooling applications in clinical diagnostics and cell imaging systems requiring stable external temperature control.

Widely recognized as a reliable external cooling solution, the Julabo FL601 is well-suited to laboratories focused on biotechnology research, molecular biology, and biomedical engineering, enhancing instrument performance by providing a dedicated, precise chilling source.

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.
