A sample handling device for a laboratory automation system comprising a first carousel with a disc supported on a first axis, a second carousel with a disc supported on a second axis parallel to the first axis, and a transfer element between the first and second carousels is presented. Each disc has recesses distributed radially about the disc perimeter. Each recess receives a tube carrier. The first carousel and the second carousel connect via a passage for transferring sample tube carriers between the first and second carousels. The transfer element is a track switch which when in a rest position partly closes the passage to separate the first carousel from the second carousel. The track switch is swiveled and/or rotated about a third axis parallel to the first axis out of the rest position for transferring a tube carrier from the first carousel to the second carousel via the passage.
