Climate chamber KBF 240

KBF 240: The Benchmark for Stability Testing and Controlled Climate Conditions

The KBF 240 constant climate chamber is specifically designed to meet the demanding requirements of stability testing, ensuring reliable and consistent performance across a wide range of applications. Engineered for precision, this chamber is a trusted choice for laboratories and industries requiring controlled temperature and humidity conditions, such as pharmaceutical research, cosmetics, and food testing.

At the heart of the BINDER KBF 240 is its innovative APT.line™ preheating chamber technology, which ensures homogeneous temperature distribution throughout the chamber. This advanced system guarantees uniform conditions, even when the unit is fully loaded, surpassing the stringent accuracy demands of ICH guidelines. Whether you’re testing samples at 25 °C or 40 °C under varying humidity levels, the KBF 240 delivers results with exceptional stability and consistency.

Temperature recovery after door openings is another area where the KBF 240 excels. Designed for efficiency, the chamber rapidly re-establishes the set parameters, with recovery times of just 5 minutes at 25 °C and 60% RH or 11 minutes at 40 °C and 75% RH after a 30-second door opening. This feature is critical for maintaining the integrity of sensitive samples and ensuring uninterrupted testing processes.

The BINDER KBF 240 offers precise humidity control with its capacitive humidity sensor and steam humidification system. Operating within a humidity range of 10% RH to 80% RH, the system maintains stable and reproducible conditions, crucial for long-term stability studies. This capability makes the KBF 240 a reliable tool for industries where environmental conditions can directly impact product quality and safety.

Efficiency and ease of use are at the forefront of the KBF 240’s design. The intuitive touchscreen controller allows users to program sequences or monitor real-time conditions with ease. Data management is made simple with the integrated data recorder, which records measurements in an open format that can be exported via USB. This eliminates the need for proprietary software and ensures compatibility with various analysis tools.

For enhanced functionality, the chamber includes an Ethernet interface, enabling remote monitoring and integration into laboratory networks. Additionally, BINDER’s proprietary APT-COM™ Basic Edition software expands data management capabilities, providing a comprehensive solution for documentation and analysis.

The KBF 240 is designed with longevity and safety in mind. Its interior, constructed entirely of stainless steel, resists corrosion and ensures easy cleaning. The safety glass inner door is hermetically sealed, preventing contamination while allowing clear visibility of the chamber’s contents. The glass is treated with a special TIMELESS coating, protecting it from corrosion over time and maintaining clarity.

Safety features are robust, with a Class 3.1 (DIN 12880) thermostat providing over-temperature protection. Both visual and audible alarms alert users to deviations, ensuring the security of valuable samples. The chamber is also equipped with stable castors, two with brakes, for effortless mobility and secure placement in any laboratory environment.

Despite its powerful performance, the BINDER KBF 240 is energy efficient, consuming only 650 Wh/h at 40 °C and 75% RH. The chamber’s optimized thermal management reduces operating costs, making it a sustainable choice for laboratories with high workloads. Additionally, its large usable volume allows for 30% more load capacity compared to competing models, maximizing productivity.

Whether used for pharmaceutical stability testing, material aging studies, or controlled environment storage, the KBF 240 delivers consistent and reliable performance. Its broad temperature range of 0 °C to 70 °C and humidity range of 10% RH to 80% RH make it suitable for a wide array of applications. Laboratories around the world rely on the BINDER KBF 240 for its precision, reliability, and user-friendly design.
