C-605 Pump Module: Compact Performance for Reliable Solvent Delivery

The Büchi C-605 pump module is a key component of BUCHI Sepacore® chromatography systems, designed to deliver exceptional performance in the field of chromatography. This module is essential for ensuring a reliable and constant solvent flow rate, crucial for obtaining reproducible results in both isocratic and gradient chromatography modes.

Designed with remarkable versatility, the C-605 can handle a wide range of solvents due to its chemically inert pump head material. This design not only ensures extensive compatibility with various solvents but also maintains consistent performance under pressures of up to 50 bar (725 psi). With a flow rate capacity of up to 250 mL/min, the module meets the demands of both routine and complex chromatographic tasks, providing an adaptable solution for diverse applications.

The C-605 features a radial 3-piston pump head, which combines a compact footprint with high performance. This compact design is paired with pulse-free solvent delivery, achieved through an innovative design that minimizes flow rate fluctuations. This ensures homogeneous sample separation and high-quality results, even in the most demanding chromatographic processes.

One of the major advantages of the C-605 is its flexibility. It allows for easy and rapid configuration according to the user's specific needs and budget. Whether transitioning from isocratic to gradient chromatography or from manual to computer control, the C-605 adapts seamlessly to your evolving needs, offering a flexible and scalable solution.

Despite its compact size, the C-605 remains powerful. With dimensions of 160 × 153 × 305 mm and a weight of just 4 kg, this module is ideal for laboratory setups where space is limited. Its compact design facilitates integration into existing systems while delivering high performance.

Technical precision is another strength of the C-605. It features a flow rate accuracy of ±2% of the set value and exceptional reproducibility at ±0.5%. Calibration options for specific solvents and temperatures ensure precise and reliable performance, suited to a wide range of chromatographic applications.

The C-605 is built with robust materials such as PEEK, sapphire, ceramic, FEP, and ruby, ensuring high chemical resistance and biocompatibility. The integrated piston back-flushing function aids in easy maintenance and durability, ensuring uninterrupted performance.

Environmental specifications for the C-605 include an operating range of 5 to 35 °C and a maximum relative humidity of 80% for temperatures up to 31 °C, decreasing linearly to 50% at 40 °C. This module is designed for indoor use up to an altitude of 2000 meters, making it suitable for various laboratory environments.

The C-605 pump module stands out for its ability to provide reliable, precise, and adaptable solvent delivery. Its compact design, flexible configuration options, and perfectioned features make it a valuable asset for any chromatographic application, ensuring high-purity results and optimal performance.
