Abstract A set of cuvettes the side walls of whose cuvettes (2) are provided with a layer (29) of material that prevents measurement radiation and/or light (22) directed at the walls from passing through the side walls. The layer (29) inhibiting the passage of the measurement radiation may be placed on the inside face and/or on the outside face of the side walls of the cuvettes (2). When the inside face of the measurement window (16) in the cuvettes (2) is coated with a thin layer (34) of the material contained in the side walls of the cuvettes and preventing the passage of radiation, the layer of coating on the measurement window is, however, so thin that it allows the passage of the major part of the radiation through the window.
A set of cuvettes intended for use in a vertical measurement photometer, said cuvette set comprising a plurality of cuvettes wherein each cuvette comprises (a) side walls which are provided with a layer of material that prevents measurement radiation and/or light directed at said walls from passing through said walls, and (b) a bottom measurement window for optical reading, wherein said measurement window is coated with a layer of the same material which is contained in said side walls, said layer being sufficiently thin to allow the passage of a majority of said radiation through said window.
