<p>Apparatus for transporting elongated sample holders in a sample holder storage compartment past an operating station at which sample tubes contained in the sample holders (12) may be removed and then returned to the sample holders. First and second parallel conveyors on opposite sides of the operating station (14) drive the holders toward and away from the operating station. Lateral drive means engage the holders in longitudinal stop positions at opposite ends of the conveyors (30, 32) to lateral stop positions, one of the holders during lateral movement being driven into and away from an operative position at the operating station. Encoded label (44, 45) means are displayed on each sample holder for indicating the incremental spacing between the sample tubes carried in the sample holder. Detector (63) means are provided for reading the encoded labels means and convey a signal in accordance with the label means to control means which control the operation of the first and second conveyor means and of the longitudinal drive means.</p> |
