ABSTRACT:
The insert for a pneumatic tube conveyor capsule holds test tubes in the capsule. The insert has a frame coaxial with the pneumatic tube conveyor capsule. The frame forms two or more trays and an intermediate tray farmed with throughholes into which the test tubes are inserted and secured axially between the two trays. A supporting column connects the two trays and the intermediate tray and has an axial plug-in connection for one of the two trays with an axial clamping device. The axial clamping device includes two spring-loaded tongues opposite one another relative to the axis of the frame, extending in the direction of the supporting column between the intermediate tray and the tray that is removably placed on the plug-in connection. The tongues are attached to or formed onto one of these structural parts and they forming a snap closure with locking recesses on the respective other structural part.
