An analyzer is described including a scanning means for containers of different diameters arranged in a tray and filled with body fluid, said scanning means being arranged at an aspirating station. The scanning means comprises two movable scanning elements and a sensor which is associated with said scanning elements and can be actuated by them. The scanning elements are arranged normal to a pivotable transporter providing a transport path for the containers and, by means of, e.g. two spring elements, retained in initial positions towards the transport path. Pivoting the transporter from a tray track to a scanning station for the containers moves the scanning elements to end positions and the sensor produces a signal which depends on the diameter of container positioned at the scanning station. A container is thereby centered and fixed in a tray by means of scanning element and spring element and tray is centered and fixed on the transport path by means of scanning element and spring element. The signal length produced by the scanning means and fed to a microprocessor of a control unit is used for controlling the position and dip-in speed of a proboscis of an aspirator when body fluid is removed from a container. |
