Abstract: A device for presentation of receptacles containing samples of liquid with a view to transferring them to an automatic analyzer. The device comprises a cylindrical drum forming a core integral with at least two circular crowns perforated or with cavities to receive the receptacles and sloping them relative to the axis of the drum which is maintained horizontal during the presentation of the samples with a view to transferring them into the analyzer. Such a device having a small bulk enables ideal agitation as a consequence of the rotation and tipping over of the samples during their presentation.
