Overview
The Thermo Scientific Haake AC200-A10 combines an Arctic A10 refrigerated bath with Thermo's advanced AC200 temperature controller. Unlike a cooling-only recirculating chiller, this system can actively heat and refrigerate its circulating fluid, allowing laboratory applications to be controlled across a broad -10°C to +100°C range.
The integrated stainless steel bath provides up to approximately 6 L of fluid capacity and can be used directly for temperature conditioning of samples and vessels. The circulation pump can also supply temperature-controlled fluid to compatible external equipment.
The AC200 controller adds sophisticated programming and monitoring capabilities to the compact A10 platform. Operators can store five commonly used temperature setpoints and create a 10-step ramp program for applications requiring controlled temperature changes over time.
Acoustic and optical alarms, adjustable high-temperature protection, and low-fluid-level protection help safeguard both the circulator and laboratory samples during operation.

Common Applications
The Thermo Scientific AC200-A10 is suitable for applications requiring controlled heating, refrigeration, or both. Typical uses include sample incubation and conditioning, analytical instrument temperature control, chemical reaction studies, calibration procedures, viscosity testing, materials research, reagent conditioning, and general laboratory temperature-control work.
The integrated bath can accommodate samples and small vessels directly, allowing the AC200-A10 to function as a precision refrigerated/heated circulating bath.
For compatible external applications, the circulation pump can supply conditioned fluid to jacketed vessels, analytical instruments, condensers, heat exchangers, and other equipment requiring a controlled fluid temperature.
The ability to program temperature ramps also makes the AC200 controller useful for procedures requiring deliberate temperature transitions rather than operation at a single fixed setpoint.
Ideal Laboratory Types
The Thermo Haake AC200-A10 is well suited for pharmaceutical and biotechnology laboratories, chemistry facilities, materials-science groups, analytical laboratories, quality-control departments, industrial R&D facilities, academic research laboratories, and other environments requiring precision temperature control.
Its relatively small footprint and 6 L maximum bath volume make it especially useful for laboratories that need refrigerated and heated circulation without the space or fluid requirements of a larger bath.
The system can also serve as a dedicated temperature-control source for an individual analytical instrument or experimental setup.
Temperature Control & Stability
The AC200-A10 provides active temperature control from -10°C to +100°C, allowing the same instrument to perform both below-ambient refrigeration and elevated-temperature heating.
Its refrigeration system provides approximately 240 W of cooling capacity at a 20°C bath temperature. Available refrigeration capacity decreases as operating temperature moves farther below ambient, so applications with significant heat loads should be evaluated according to the cooling capacity available at the intended setpoint.
The AC200 controller uses electronic temperature regulation and continuous fluid circulation to maintain consistent bath conditions. Five programmable setpoints allow frequently used temperatures to be recalled quickly.
For procedures requiring changing temperatures, the controller also provides a 10-step ramp program. This can be useful for experiments involving controlled heating or cooling sequences rather than a single constant temperature.
Heat-transfer fluid should always be selected according to the intended operating temperature. Water is suitable for only part of the AC200-A10's full -10°C to +100°C range.
Circulation & Pump Performance
The AC200 controller uses a three-speed force/suction pump capable of circulating fluid at rates up to approximately 20 L/min.
Continuous circulation promotes temperature uniformity throughout the bath and efficiently transfers heating or refrigeration energy between the temperature-control system and immersed samples.
The force/suction pump also allows temperature-controlled fluid to be circulated through compatible external equipment. Thermo designed this pump arrangement to support both closed-loop applications and appropriate open external systems.
Pump speed can be adjusted according to the application, providing flexibility when working with different bath loads or external circulation circuits.
Actual external flow depends on tubing dimensions, fittings, heat-transfer-fluid viscosity, operating temperature, elevation, and hydraulic resistance within the connected equipment.
Refurbishment & Testing
This used Thermo Scientific Haake AC200-A10 Refrigerated/Heated Bath Circulator is refurbished and tested by American Instrument Exchange before shipment. Our technicians inspect the refrigeration system, heater, circulation pump, AC200 controller, display, bath, safety systems, electrical components, and fluid connections.
Temperature-controlled equipment is tested using NIST-traceable probes and data loggers. Because the AC200-A10 provides both heating and refrigeration, the system is operated for extended periods at both lower and higher temperatures to evaluate heating, cooling, circulation, and temperature regulation.
The bath, reservoir, and accessible fluid-contact components are also cleaned and inspected before shipment.
If your application requires operation at a specific temperature or has particular testing requirements, contact American Instrument Exchange before shipment. When practical, our technicians can incorporate customer-requested operating conditions into final testing.
A 90-day warranty is included with this refurbished Thermo Scientific circulator.
Choosing the Right Refrigerated/Heated Circulator
The Thermo AC200-A10 is particularly useful for laboratories that need both refrigerated and heated temperature control in a compact bath. Its -10°C to +100°C operating range covers many routine laboratory applications without requiring separate heating and cooling equipment.
Bath size should be considered carefully. The A10 provides a working fluid volume of approximately 4–6 L and a relatively compact work area. This is advantageous for small samples and dedicated instrument applications but may not provide enough space for larger vessels or high-throughput workflows.
Thermal load is equally important. With approximately 240 W of refrigeration capacity at 20°C, the A10 is intended for relatively modest cooling loads. Equipment generating substantially more heat may require a larger refrigerated circulator or dedicated recirculating chiller.
For laboratories requiring a larger bath, lower minimum temperature, higher maximum temperature, or greater cooling capacity, Thermo Arctic systems such as the A25 or larger refrigerated circulators may be more appropriate.
American Instrument Exchange can help compare available used and refurbished laboratory circulators based on bath size, temperature range, cooling capacity, pump requirements, and application.
