Abstract
An analyzing apparatus for measuring samples of a liquid has feeding means for feeding the samples contained in sample containers to a subsequent sample conduit, the feeding means having a substantially funnel shaped filling mouth serving for fastening sample containers of very different shapes, such as syringes, pipettes or capillary tubes, and the dimensions of the outlet opening thereof varying within wide limits. A cleaning device can be used, which has a washing body which during the cleaning operation, together with the funnel shaped filling mouth, defines an annular gap adapted to match the form of the filling mouth and is providable with a cleaning medium. To ascertain the presence and opening diameter category of a sample container and to automatically adjust the appropriate operating condition of the analyzing device, at a distance before the sample feeding inlet, an oscillation emitter and, with respect to the center of the sample feeding inlet, diametrically opposite the emitter and at a distance from the center of the sample feeding inlet, at least two identical detectors for the emitter oscillations are arranged, whereby according to the respective number of detectors…
