Abstract: Apparatus and processes for automated diagnostic testing may include cuvette dispensing, test sample dispensing, reagent dispensing, incubation, photo-optical measuring, and a control in operative communication with the cuvette dispensing unit, the test sample dispenser, the reagent dispenser, the incubation unit, and the measuring unit. A cuvette removal location, a reagent removal location, a measuring location, and a collection receptacle may be situated along a first common circular arc having first geometric center. A cuvette-moving arm and a reagent-dispensing arm have a common axis of rotation passing through this geometric center. A sampling position, a sample dispensing position, an additional rinsing position, and an additional washing position, may all be provided on a second circular arc having second geometric center that has a second axis of rotation for a rotatable sampling arm of the test sample dispenser.

Abstract: Apparatus and processes for placing sample cuvettes at measuring points, dispensing a reagent into the cuvettes, and forwarding used cuvettes to a receptacle after finishing the measurements. The apparatus has an incubation module (1) for incubating sample cuvettes (7), a reagent module (3) containing a reagent of an amount needed for the assay, and a measuring module (2) favorably accommodating optical measuring points. Arms (K1 . . . KN) can move the sample cuvettes (7).
