Themo Scientific A10B refrigerated circulator Overview

The Thermo Scientific Haake ARCTIC A10B combines a large stainless-steel working bath with heating, mechanical refrigeration, active fluid circulation, and the SC100 digital temperature controller.

Its large working area is one of the principal differences between the A10B and smaller refrigerated circulators. Thermo designed the A10B specifically to provide increased sample capacity and working space for applications where materials, vessels, test equipment, or multiple samples must be placed directly into a temperature-controlled bath.

The system can operate from approximately -10°C to +100°C, allowing the same circulator to perform both refrigerated and heated applications. Active fluid circulation continuously distributes thermal energy throughout the reservoir, helping maintain consistent temperature conditions across the working area.

The A10B is not limited to direct bath applications. External circulation connections allow temperature-controlled fluid to be pumped through compatible laboratory equipment and returned to the bath.

This combination of large direct-access working volume and external circulation capability makes the A10B a particularly versatile laboratory temperature-control system.

Common Applications

The Themo Scientific A10B refrigerated circulator is suitable for a broad range of laboratory procedures requiring precise refrigerated or heated temperature control. Common applications include sample conditioning, materials testing, calibration, reagent preparation, viscosity studies, chemical reaction control, bioreactor temperature control, rotary evaporation, condenser cooling, and general research.

The large bath is especially useful for direct-immersion applications. Multiple sample containers can be maintained at the same controlled temperature, while larger laboratory vessels and test fixtures can be accommodated more easily than in a compact refrigerated circulator.

For calibration and materials-testing applications, the approximately 11.7 × 13.4-inch working area provides substantial space for temperature probes, sensors, components, and test samples.

External circulation expands the system's capabilities beyond the bath itself. The A10B can provide temperature-controlled fluid to compatible jacketed vessels, condensers, heat exchangers, analytical equipment, and other closed-loop laboratory systems.

Ideal Laboratory Types

The Thermo Scientific Haake ARCTIC A10B is well suited for pharmaceutical and biotechnology laboratories, analytical laboratories, chemistry and process-development groups, calibration laboratories, materials-science facilities, quality-control departments, industrial R&D laboratories, manufacturing support laboratories, and academic research environments.

Its large bath volume makes it particularly attractive for laboratories processing multiple samples simultaneously or working with larger vessels and test components.

Facilities that perform both direct-bath and external-circulation applications can also benefit from the versatility of a single system capable of performing both functions.

Performance & Temperature Stability

The Thermo Scientific Haake A10B operates across a broad -10°C to +100°C temperature range with approximately ±0.02°C temperature stability when properly configured and operated.

The SC100 controller continuously monitors bath temperature and regulates heating and refrigeration to maintain the selected setpoint. Active fluid circulation distributes conditioned fluid throughout the stainless-steel reservoir, improving heat transfer and helping minimize temperature gradients.

Mechanical refrigeration allows controlled operation below ambient temperature without relying on ice or facility cooling water. Thermo specifies approximately 250 W of refrigeration capacity for the A10B.

At elevated temperatures, the integrated heating system allows the bath to operate up to approximately +100°C.

Actual performance depends on operating temperature, fluid selection, ambient conditions, bath loading, external heat load, circulation configuration, and whether the working area is covered.

For applications approaching the upper temperature limit, a suitable bath cover can help reduce evaporation and heat loss. Thermo lists a work-area cover as an accessory for the Themo Scientific A10B refrigerated circulator rather than standard equipment.

Refurbishment & Testing

This used Thermo Scientific Haake ARCTIC A10B Refrigerated Circulator is refurbished and tested by American Instrument Exchange before shipment. Our technicians inspect the compressor, condenser, refrigeration circuit, heater, circulation pump, SC100 controller, display, temperature sensor, stainless-steel reservoir, external circulation connections, electrical components, drain, and applicable safety systems.

Temperature-controlled equipment is tested using NIST-traceable probes and data loggers. Because the A10B provides both refrigeration and heating, the circulator can be operated at multiple temperatures to evaluate pull-down performance, heating, circulation, temperature regulation, controller response, and overall system stability.

The bath and accessible fluid-contact components are cleaned and inspected before shipment.

Customers requiring the A10B for a specific operating temperature, sample-testing procedure, or external circulation application are encouraged to provide their requirements before shipment. When practical, American Instrument Exchange can incorporate customer-requested operating conditions into final testing.

A 90-day warranty is included with this refurbished Thermo Scientific refrigerated circulator.

Shipping & Installation

The Thermo Scientific Haake A10B weighs approximately 98 lb and should be transported with the bath drained and the refrigeration system properly protected. American Instrument Exchange prepares the unit for commercial shipment with appropriate protection for the refrigeration system, SC100 controller, bath, housing, and fluid connections.

After installation, the bath should be filled with an appropriate heat-transfer fluid selected for the intended temperature range. Plain water may be appropriate for many moderate-temperature applications, while subzero or elevated-temperature operation may require a different compatible fluid.

The A10B uses a three-sided ventilation concept that provides useful flexibility when positioning the unit in a laboratory. Thermo specifies that up to two sides can be blocked while maintaining refrigeration performance, although the equipment should still be installed according to manufacturer ventilation and service-access requirements.

External circulation fittings should be securely connected before operation when the bath is used with external equipment.
