Abstract:
1. A cuvette for taking a measurement of a liquid, comprising a one-piece cuvette body having a longitudinal axis and a cavity in the form of a narrow slot, said slot being defined by two at least approximately parallel wall surfaces a measuring region formed by the cavity, a drawing edge open to the outside of the cavity and adapted to draw liquid into the cavity by capillary action, an inner wall delimiting the cavity and having longitudinal wall sections starting from the drawing edge, an end region that connects the longitudinal wall sections, and a coating of the cavity with a chemical reagent of the kind that is applied in the wet state and then dried as a result of gases evaporating out of the cavity, wherein a drawing section of said drawing edge is positioned at a spacing from the longitudinal wall sections, the longitudinal wall sections extend distant from either side of a flow center axis running centrally from the drawing edge to the end region, the end region has an opening to the outside, and marginal regions are formed along the longitudinal wall sections and have a spacing between delimiting surfaces which is greater than the spacing between the adjacent parallel wall surfaces.
