Shimadzu CBM-20A

The Shimadzu CBM-20A is a used system controller module that serves as the communications hub for Prominence series HPLC systems, coordinating data flow between pumps, detectors, autosamplers, and column ovens. It plays a central role in ensuring that all modules in a chromatography stack operate in sync, translating instructions from control software into coordinated instrument action. This controller is a key piece of infrastructure for labs relying on Shimadzu's Prominence platform. Built to manage multiple connected devices simultaneously, the CBM-20A supports complex method sequences and multi-module configurations commonly found in pharmaceutical, environmental, and industrial testing laboratories. Its reliable data handling and connectivity make it an essential backbone component, and labs often need to source a working replacement quickly to avoid downtime on an otherwise functional HPLC system. Offered here as a used unit removed from an operating laboratory, this CBM-20A is ready to bring a Prominence series HPLC system back online. It represents a practical and economical solution for labs facing a failed controller or looking to build a complete secondary system from existing modules.
