Thermo Scientific Haake C10 Refrigerated Circulator

The Thermo Scientific Haake C10 Refrigerated Circulator is a laboratory temperature-control system designed for precise heating, refrigerated cooling, and fluid circulation. Combining the Haake C10 analog thermostat with a refrigerated bath, this system can be used for direct temperature control of samples within the reservoir or for circulating temperature-controlled fluid through compatible external laboratory equipment.

Available used and refurbished from American Instrument Exchange, the Thermo Haake C10 provides approximately ±0.04°C temperature accuracy, active heating and cooling, and external circulation capability in a durable laboratory platform. The C10 was offered with several refrigerated bath configurations, allowing the system to support applications ranging from routine subambient temperature control to more demanding low-temperature procedures. A 90-day warranty is included.

Overview

The Thermo Haake C10 is part of an established generation of laboratory circulators designed for dependable heating, cooling, and temperature-controlled fluid circulation.

The C10 designation refers specifically to the thermostat and circulation controller. Thermo Haake paired the C10 with multiple refrigerated bath configurations that provided different reservoir capacities, minimum temperatures, and cooling capacities.

This modular design made the C10 platform useful across a broad range of laboratory procedures. Samples and vessels can be placed directly into the temperature-controlled bath, while the integrated circulation pump can also supply fluid to compatible equipment outside the reservoir.

Compared with more sophisticated digital controllers, the C10 uses a relatively straightforward control interface. This simplicity can be advantageous for laboratories requiring reliable temperature control without complex programming or communication functions.

Key Specifications

Common Applications

The Thermo Haake C10 is suitable for laboratory procedures requiring controlled heating or refrigeration. Typical applications include sample conditioning, chemical reaction control, viscosity studies, calibration work, materials testing, reagent temperature control, condenser cooling, jacketed vessel temperature control, and general laboratory heating and cooling.

The refrigerated bath allows samples and vessels to be immersed directly in temperature-controlled fluid, while external circulation connections extend the system's usefulness to compatible laboratory equipment.

This versatility can make the C10 useful for laboratories that would otherwise require separate water baths, refrigerated baths, and external fluid circulators.

Ideal Laboratory Types

The Thermo Scientific Haake C10 is well suited for chemistry laboratories, pharmaceutical and biotechnology facilities, materials-science groups, analytical laboratories, industrial R&D facilities, quality-control departments, academic research laboratories, and other environments requiring reliable fluid temperature control.

Its straightforward controls may be particularly attractive for routine procedures that do not require complex temperature programming or computer communication.

The C10 can also be a practical option for laboratories maintaining older instruments or experimental systems originally designed around Haake circulating baths.

Temperature Control & Stability

The Thermo Haake C10 thermostat provides temperature accuracy of approximately ±0.04°C when properly configured and operated.

The actual working temperature range depends on the refrigerated bath attached to the C10 controller. Thermo Haake offered multiple configurations with substantially different low-temperature capabilities.

For example, historical C10 systems equipped with a K10 refrigerated bath were rated from approximately -10°C to +100°C, while C10-K15 systems extended the lower operating temperature to approximately -28°C.

Because of these configuration differences, the exact temperature range of this individual C10 should be determined from the complete model designation and refrigerated bath rather than from the C10 controller name alone.

The system also provides active heating. C10 controllers were rated at approximately 1.0 kW heating capacity in 115 V configurations and approximately 1.5 kW in 230 V configurations.

Circulation & Pump Performance

The Thermo Haake C10 includes active fluid circulation for both internal bath agitation and compatible external temperature-control applications.

Within the reservoir, continuous fluid movement improves heat transfer and helps maintain consistent temperature around immersed samples.

External circulation allows the C10 to supply heated or refrigerated fluid to compatible jacketed vessels, condensers, heat exchangers, analytical equipment, and other laboratory devices.

Pump performance varies according to the complete C10 bath configuration. Historical Thermo Haake systems in this family commonly provided maximum pump pressure around 300 mbar, while maximum flow varied according to the bath and circulation arrangement.

Actual external flow also depends on tubing length and diameter, fittings, fluid viscosity, operating temperature, elevation, and hydraulic resistance within the connected equipment.

For applications with defined flow or pressure requirements, American Instrument Exchange can verify the configuration of the individual circulator before shipment.

Refurbishment & Testing

This used Thermo Scientific Haake C10 Refrigerated Circulator is refurbished and tested by American Instrument Exchange before shipment. Our technicians inspect the refrigeration system, heater, circulation pump, temperature controller, reservoir, condenser, electrical components, safety controls, and external circulation connections.

Temperature-controlled equipment is tested using NIST-traceable probes and data loggers. The system is operated for extended periods to evaluate refrigeration, heating, circulation, temperature regulation, controller operation, and overall stability.

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

If your application requires operation at a specific temperature or has defined flow, pressure, or 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 Haake circulator.

Choosing the Right Circulator or Water Bath

The Thermo Haake C10 is particularly useful for laboratories that need both direct bath temperature control and external fluid circulation.

Unlike a conventional non-circulating water bath, the C10 actively moves fluid through the reservoir to improve temperature distribution. External circulation connections also allow the same system to control compatible equipment outside the bath.

The complete bath configuration is particularly important when evaluating a C10. Different Thermo Haake refrigerated baths provide different minimum temperatures, cooling capacities, reservoir volumes, and circulation characteristics.

Laboratories requiring a particular subambient temperature should therefore verify the complete C10 configuration rather than selecting a unit based solely on the C10 controller designation.

American Instrument Exchange can help compare available used and refurbished circulating baths based on required temperature range, cooling capacity, bath size, pump performance, electrical service, and application.
