Shimadzu CTO-20A

This used Shimadzu CTO-20A is a column oven module from the Prominence series, built to deliver precise and stable temperature control for HPLC columns during analytical separations. Reliable thermal management is a core requirement for reproducible chromatography, and the CTO-20A was designed to meet that need across a wide variety of method types and sample matrices. It remains a popular choice among labs running Prominence-based HPLC configurations. The unit supports a broad temperature range and can accommodate multiple column configurations, giving analysts flexibility when developing or running validated methods. Laboratories in pharmaceutical development, quality control, and academic research settings rely on this type of module to keep retention times consistent from run to run and operator to operator, supporting both routine testing and more demanding regulatory work. As a pre-owned module, this CTO-20A has been removed from an operating laboratory and is offered in working order for labs looking to repair, expand, or build out a Prominence series HPLC system. It offers a cost-effective path to restoring full functionality to an existing chromatography setup.
