LC-4000 Series HPLC Column Ovens

HPLC Column Ovens

The LC-4000 Series HPLC column ovens have been designed to provide excellent utility for a wide range of different user requirements.

All HPLC column ovens have built-in electronic cooling for controlling column temperature at sub-ambient temperatures. The CO-4062 and CO-4061 block-heater type ovens can be fitted with an optional micro-volume pre-heating unit for pre- heating the mobile phase before the column to improve resolution and peak shape.

CO-4061

For simple requirements the stackable CO-4061 can be used with column lengths up to 200mm (or up to 300mm with an optional extension).

CO-4062

For RHPLC and UHPLC the CO-4062 has capacity for up to six 150 mm length columns, with optional one or two internally mounted automatic switching valves for 2 or 6 column selection.


 

CO-4060/CO-4065

For GPC and larger preparative columns, select either of the two high-capacity CO-4060 or CO-4065 HPLC column ovens. The CO-4060 can accommodate columns with lengths up to 300mm or larger ID preparative columns. The CO-4065 can accommodate up to 10 columns with lengths up to 300mm and a pair of column selection valves is included as standard.
