Patent attributes
Cuvette, comprising a first flat plate (1) and a second flat plate (2), both of which in a closed state of the cuvette are positioned so as to be situated opposite parallel to each other and at which there is at least one transparent first measuring surface (1.1) and at least one transparent second measuring surface (2.1), which define in pairs a measuring space (3), in which a liquid sample solution having a drop volume can be held by means of its surface tension and capillary forces. At least the second measuring surface (2.1) of each one of the measuring spaces (3) is a stepped surface, which has at least two plane-parallel partial measuring surfaces (2.1.1, 2.1.2), which are connected to each other by means of a setting surface (2.1.0), so that the partial measuring surfaces (2.1.1, 2.1.2) exhibit different vertical distances (b1, b2) from the first measuring surface (1.1).
