Abstract: A column oven comprises: a hollow housing; an analysis column arranged in the housing and allowing circulation of a mobile phase in the analysis column; a heating portion configured to heat air; a swirl flow generation portion configured to discharge, as a swirl flow, the air heated by the heating portion into the housing; and a throttle portion configured to throttle the swirl flow when the swirl flow is discharged into the housing. The throttle portion has multiple through-holes formed to penetrate the throttle portion along a direction of discharging the swirl flow and arranged in a honeycomb shape as viewed from a swirl flow discharge side.

Abstract: For providing a column oven and chromatography capable of reliably preventing misconnection of a storage unit to a connecting part, the column oven includes: a hollow casing; a column unit including an analysis column, which is arranged in the casing and allows a mobile phase (Q) to flow through, and a storage unit, which is attached to the analysis column and stores data of the analysis column; multiple holding parts, which are arranged in the casing and hold the analysis column; a tabular fixing plate, which is arranged in the casing and fixes the respective holding parts to the casing; multiple connecting parts, which are arranged in the casing and connect the storage unit electrically and detachably; and a heating part, which heats the analysis column held by the holding parts in the casing. When viewing the analysis column from a side facing the fixing plate with the analysis column held by the holding parts, the connecting parts connected to the storage unit of the column unit including the analysis column are arranged adjacent to the analysis column.

Abstract: A cap attachment-detachment device includes an operation portion that moves in an up-and-down direction, and grips and rotates a cap so as to attach the cap to or attach the cap from a container. The operation portion includes a first grip claw, a second grip claw and the pressing member. The first grip claw and the second grip claw are provided to be opposite to each other and configured to be capable of applying an obliquely upward force inwardly to an upper portion of a side surface of the cap. The pressing member is configured to be capable of coming into contact with an upper surface of the cap.
