A measuring system and method are provided for performing luminometric series analyses on reaction components to be investigated and the liquid samples containing the magnetizable carrier particles binding the components. Sample chambers receive the liquid samples. These sample chambers are transported to a measuring station on a conveyor. Permanent magnets act on the sample chambers with magnetic fields during transport. A separating station is also provided, which is preferably equipped with a suction and rinsing device to remove the surplus reaction components separated from the carrier particles that accumulate on wall areas of the sample chambers under the influence of the magnetic fields.
Multiple cuvette for receiving liquid samples for luminometric series analyses with cuvette units connected together in rows and each forming a sample chamber, with cuvette units (30) having a lower measuring chamber area (32) and a loading area (36) located above and widening to form a loading opening and being formed to be trapezoidal or triangular in cross section, and having a transparent optical measuring window (40) on one side wall (31) that covers measuring chamber area (32), and with cuvette units (30) being connected rigidly together by vertical connecting ribs (46, 48) extending at the level of the loading areas (36) and by horizontal connecting areas (50) located at the level of the loading openings (34), characterized in that the connecting ribs (46, 48) on the measuring window side (42) and the opposite rear side (44) each have an emission window (64, 58) that prevents light from passing between adjacent cuvette units (30).
