CANADIAN PATENT APPLICATIONOFJAN EVERT LILJAandSVEN ERIK LENNART NILSSONFORAbstract of the DisclosureA cuvette for sampling with a cavity which is defined bytwo planar surfaces which are placed or can be placed at a pre-determined distance from one another. A reagent is contained inthe cavity in an amount which is exactly determined in relationto the volume of the cavity. The sample is drawn into the cavitypreferably by capillary force and mixed with the reagent there-in spontaneously or by vibration, whereupon optical analysistakes place directly through the two planar surfaces.
