Device for transporting containers filled with a liquid

An analyzer is described which includes an input station (1) for trays (5) carrying containers (4) filled with body fluids. It consists of a plurality of tray tracks (3) arranged side by side and whose central axes (6) intersect in a point (7) which also forms the fulcrum (84) of a pivotally arranged transport path (12). The transport path can be aligned with any of the tray tracks (3). By means of a tray movement member (14) the tray (5) can be transported from the input station (1) to the processing stations (15 or 16) and back. The exits (10) of the tray tracks (3) are associated with retaining means (19) which are controlled in the same way as the stepping motors (61 and 69) in response to sensors (27, 32, 68) and a microprocessor (78).
