HPLC Column Ovens


Shimadzu offers three different types of column ovens covering a wide range of applications. With both block-heating and forced air circulation designs, accurate column heating is achieved providing reproducible chromatography for high-throughput analysis.

CTO-20A/AC

CTO-20A/AC Column Oven

The CTO-20A and CTO-20AC are forced air circulation column ovens with a temperature range up to 85°C. A high-performance thermistor regulates the temperature for enhanced accuracy for achieving reproducible chromatography. The CTO-20AC is capable of cooling allowing for complex temperature programs involving both heating and cooling.

CTO-30A

CTO-30A Column Oven

The CTO-30A is a compact block-heating column oven with a temperature range up to 150°C. This column oven uses an intelligent heat balance mechanism to achieve uniform temperature control for improved chromatography.

CTO-30AS

CTO-30AS Column Oven

The CTO-30AS is a small, single column oven that can be installed on the side of the SIL-30ACMP autosampler. This oven uses a block heating design (temperature range up to 85°C) and can be aligned with a detector inlet line to minimize peak dispersion for LCMS applications.
