Laboratory sample container handling apparatus, laboratory automation system, and use

A laboratory sample container carrier handling apparatus comprising:

• a revolving device;
• a guiding surface;
• a force-applying device;
• and
• a laboratory sample container carrier rotating apparatus,
• wherein the guiding surface comprises an open ring shape partially surrounding the revolving device circumferentially,
• wherein the revolving device is adapted to push a laboratory sample container carrier supplied to the revolving device along the guiding surface,
• wherein the force-applying device is adapted to apply a force to the laboratory sample container carrier supplied to the revolving device to such an extent that the laboratory sample container carrier is forced against the guiding surface to such an extent that the laboratory sample container carrier rolls off at the guiding surface pushed by the revolving device,
• an optical reader, and
• wherein the laboratory sample container carrier rotating apparatus is adapted to rotate the laboratory sample container carrier carrying a laboratory sample container comprising an optically readable identification element into alignment of the optical reader, and wherein the laboratory sample container carrier handling apparatus is arranged such that the laboratory sample container carrier carrying the laboratory sample container comprising the optically readable identification element in alignment rolls off at the guiding surface.
