Büchi C-660 Fraction Collector with C-601 Pump Module and C-615 Pump Manager

The Büchi C-660 Fraction Collector is designed for precise compound collection essential in *biotechnology* and *molecular diagnostics*. It supports sample collection based on *time*, *volume*, or *peak mode* into various tube types or vessels, enabling automated and flexible workflows commonly required in *bioprocessing* and *synthetic biology research*. Programmable delay time enhances timing accuracy for fraction collection critical in biopharmaceutical production pipelines.

The integrated Pump Module C-601, coupled with the Pump Manager C-615, offers reliable and consistent solvent delivery optimized for chromatography and other liquid handling applications. Key features include:

• Pressure capacity: Maximum 10 bar (145 psi) for Pump Module C-601, with flow rates up to 250 mL/min
• Flow control: Pump Manager C-615 regulates flow rates of up to two pump modules simultaneously, monitoring current system pressure for operational safety
• Pump technology: 3-piston pump head ensures pulse-free solvent delivery, critical for reproducible gradients in analytical and preparative chromatography
• Compact footprint: Space-efficient design beneficial for laboratories with limited benchtop space, supporting applications in clinical diagnostics and biotechnology labs

This system is widely used in research fields such as *live-cell imaging*, *fluorescence analysis*, and *biomanufacturing*, where precise fractionation and solvent control improve experimental reproducibility and downstream processing efficiency. Its combination of accurate fraction collection with advanced pump management makes it essential for molecular cloning workflows and bioprocess optimization in synthetic biology settings.
