摘要： A turbidimeter for measuring a turbidity of a liquid sample in a sample cuvette includes a cuvette receiving device configured to position the sample cuvette in a defined cuvette position, a light source configured to generate a parallel light beam in the sample cuvette, an annular 45° collecting mirror configured to surround the sample cuvette, a scattering body arranged concentric to the annular 45° collecting mirror, a scattering light detector arranged to receive light scattered by the scattering body, and an annular 45° concentration mirror arranged coaxially to the annular 45° collecting mirror and optically opposite to the annular 45° collecting mirror. The annular 45° collecting mirror is arranged concentric to the light beam. The annular 45° concentration mirror is configured to surround the scattering body.

摘要： A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a sample cuvette. The nephelometric turbidimeter includes a measurement light source configured to emit an axial parallel light beam directed to the sample cuvette, a scattering light detector arranged to receive a scattered light from the sample cuvette, and a diffuser comprising a diffuser body and a diffuser actuator. The diffuser actuator is configured to move the diffuser body between a parking position in which the diffuser body does not interfere with the axial parallel light beam and a test position where the diffuser body is arranged between the measurement light source and the sample cuvette so that the diffuser body interferes with the axial parallel light beam and generates a diffuse test light entering the sample cuvette.

摘要： Disclosed is a process photometer arrangement (10) with a photometric cuvette unit (20) comprising a cuvette body (24) defining a cuvette cavity (25) and a combined sample inlet/outlet opening (34), a photometer light inlet window (60) and a photometer light outlet window (62). The cuvette body (24) is movably supported by a cuvette body support element (88) and the cuvette unit (20) is provided with a cuvette vibration device (80) for vibrating the cuvette body (24) to thereby quickly and homogenously mix a liquid sample volume (31) within the cuvette cavity (25) without any separate mixing element within the cuvette cavity.
This allows a short mixing action within a microfluidic cuvette.
