Abstract: Reaction segment for a colorimetric analyzer is removably mounted on a revolving plate of the analyzer so that the reaction vessels of the segment are brought one after the other into contact with a measuring device of the analyzer. The segment consists of transparent vertical reaction vessels which are rigidly fixed to a horizontal bar having connected thereto a horizontal plate to which is affixed a device for positioning and guiding into loading and unloading devices of the analyzer and into the opening of the revolving plate.

Abstract: A device for automatically analyzing samples by a colorimetric procedure may be particularly used for blood analysis. A reaction ring bearing at its periphery an array of transparent reaction cups is stationary. An optical fiber is mounted on a rotating disk, concentric with the reaction ring and downwardly oriented with respect to the top of a cup, the optical fiber having one end at a central location where it receives light from a stationary light source and its other end opposite a bottom of a reaction cup in alignment with a measuring photomultiplier.
