F3-K Refrigerating Circulator by Haake: Precision Cooling and Heating for Laboratory Applications

The F3-K refrigerating circulator by Haake is a powerful, compact, and versatile system engineered to provide precise temperature control in a range of laboratory applications. Combining the high performance of the F3 circulator with an integrated refrigerating bath, the F3-K offers a broad temperature range from -40°C to 150°C, making it ideal for processes that require both cooling and heating. This robust system ensures stable thermal regulation, whether you're working with liquid samples in containers, solid samples immersed directly into the bath, or controlling the temperature of external vessels.

One of the key strengths of the F3-K is its temperature control accuracy, achieved through Haake's proprietary ANTIDRIFT technology, which ensures a precise and stable temperature control with an accuracy of ±0.02°C. This minimizes fluctuations and drifts, ensuring reliable and repeatable results, even in long-term experiments. The Pt 100 control sensor further enhances precision, enabling fine adjustments that cater to the most demanding laboratory requirements. With a digital/LED display, users can set the temperature easily and monitor it in real time with a resolution of 0.1°C.

The F3-K offers outstanding performance thanks to its 2000 W heater capacity and an efficient compressor cooling system. The unit is equipped with one air-cooled compressor that provides robust cooling capacity at different temperatures: 270 W at -40°C, 380 W at -10°C, and 380 W at 20°C, ensuring rapid temperature adjustments. This efficiency allows the F3-K to maintain its operating range even at sub-zero temperatures, ideal for tasks requiring freezing-point control and beyond.

The F3-K is designed to handle a wide range of laboratory processes, offering support for open and closed external vessels. In open vessels, such as baths or containers, the thermal liquid is pumped into the vessel, sucked back, and recirculated to maintain a stable temperature. For such setups, Haake provides an optional level controller to maintain consistent liquid levels. In closed systems, the temperature-controlled liquid is pumped through jackets or heat exchangers, with the 210 mbar pressure pump and 16 L/min flow capacity ensuring efficient circulation, while the 170 mbar suction pump manages liquid recovery at 14 L/min.

Compact and practical, the F3-K's dimensions are 400x400x660 mm, making it easy to integrate into most lab spaces. The bath opening measures 295x190 mm with a depth of 150 mm, accommodating a wide range of sample sizes with a total bath volume of 12 liters. Its weight of 45 kg ensures stability while still being manageable for positioning in the lab.

The system also includes a low liquid level limiter, which triggers at a fixed point to prevent damage from operating with insufficient liquid. This safety feature helps to maintain system integrity and ensures uninterrupted operations.

The F3-K supports a wide range of temperature-controlling liquids, making it suitable for various media types and experimental requirements. Combined with its intuitive digital controls, efficient pump system, and high-temperature accuracy, the F3-K delivers the performance needed to handle critical processes in fields like chemistry, biology, and material sciences.
