Product description

Precise digital refrigerated heating circulator with 7L capacity, -40°C to 200°C range, and variable-speed pump.

The PolyScience AD07R series refrigerated heating circulator features a 7-liter reservoir for reliable temperature control in laboratory applications such as biotechnology, molecular diagnostics, and bioprocessing workflows. It supports a broad temperature range from -40°C (-40°F) to 200°C (392°F), accommodating both cooling and heating functions crucial for synthetic biology experiments and biomanufacturing processes.

Key technical specifications include:

  • Temperature stability of ±0.01°C (±0.02°F) ensures high precision essential for sensitive cell culture and enzymatic reactions.
  • A powerful variable-speed duplex pump delivers a maximum pressure of up to 4.3 psi (0.30 bar) and flow rates from 2.9 to 5.3 gpm (11.0 to 20.1 lpm), allowing flexible external circulation setups in open or closed loops.
  • Cooling capacities vary between 200W and 360W depending on the model, providing effective heat exchange for demanding live-cell imaging and fluorescence analysis protocols.
  • The Dura top-plate is chemical and heat resistant, supporting diverse experimental conditions without degradation.
  • Large digital display with 180° viewing radius simultaneously presents set point, actual temperature, and external probe data with intuitive icon indicators for heating, cooling, and circulation.
  • Compact dimensions (9 x 22 x 25 inches) and a weight of 90 lbs enable convenient lab bench placement.

This refrigerated circulator is widely used in clinical diagnostics labs, biotechnology research facilities, and biomedical engineering environments where stable and versatile temperature control is critical. It is especially valuable for tasks that require precise temperature modulation such as molecular cloning workflows and biopharmaceutical production pipelines.

The PolyScience AD07R represents a robust, accurate solution for laboratories demanding high-performance temperature regulation in complex biological and chemical research 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?

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.
