Abstract:
A photometer for determining the transmission of a liquid sample in a microcuvette (7, 20, 22) having a cavity for a capillary layer of the liquid sample with a free liquid surface extended transversely of the principal plane of the cavity, which is initially prepared with a reagent to achieve a reaction, which affects the transmission of the liquid sample to determine its contents of a predetermined substance, said photometer having a holder (6; 6') for the microcuvette and measuring means (9, 10; 9') for measuring the transmission of a bundle of rays directed towards the microcuvette, characterized in that the cuvette holder (6; 6') is mounted in bearings for vibration in a direction having a component which is positioned in the plane of the free liquid surface and parallel with the principal plane of the cavity, thereby achieving a mixing to accelerate dissolution and reaction.
