Abstract: A conveying system for material samples, especially medical samples, comprising a conveyor track forming at least one conveying section and a plurality of sample holders, designed to hold one sample vessel, which are self-propelled and displaceable along the conveying section. Each sample holder comprises a drive motor, an energy accumulator for supplying the motor with driving energy, at least one fiction wheel, drivable by the motor, for transmitting a force onto the track, and a control for controlling the travels of the sample holders. Signal transmitters are arranged in the track in predetermined positions along the conveying section and are adapted to form a near-field transmission section having signal receivers arranged in the sample holders, the signal transmitters being connected to the control and adapted to transmit control data relating to the adjustment of driving parameters to the sample holders via the near-field transmission section.

Abstract: A holder for cylindrical or conical containers includes holding fingers distributed around a vertical central axis. Each finger has a base attached in a connecting region to a base area and includes a first finger segment extending from the base to an area at maximum distance from the base area. The outer area of the finger is tiltable away from the axis away from a base position about a first hinge in the connecting region. A second finger segment extends outwardly from the first finger segment and from a second hinge formed in the outer area to a free end. In the base position, these second finger segments extend at an angle relative to the axis so that the free ends are closer to the axis than the outer areas. The free ends of the second finger segments are displaced outward, away from the axis via the second hinges.
