Micro cuvette assembly for examining biological samples has a first partial plate with one or more first cuvette surfaces and a second partial plate opposite the first and which also has one or more second cuvette surfaces. In an active position of the assembly, the second cuvette surfaces are arranged parallel and in register with the first cuvette surfaces and are spaced apart from the first cuvette surfaces whereby one or more micro cuvettes are formed. The first and second partial plates also have openings arranged in register with the cuvette surfaces and transparent bodies are provided as the cuvette surfaces. The first and second plates are completely penetrated by these openings and the transparent bodies are manufactured from a different material than the partial plates and span the openings close to a first surface of the partial plates. The first and second cuvette surfaces of a micro cuvette in the active position are wetted by a liquid volume which has previously been applied to one of the cuvette surfaces so that the liquid volume is held between these two cuvette surfaces.

Micro cuvette assembly for examining biological samples

Relates to a micro cuvette assembly (), comprising a first partial plate () with one or more first cuvette surfaces () and a second partial plate () which is arrangeable relative to the first partial plate and has at least one or more second cuvette surfaces () which, in an active position of the micro cuvette assembly (), are arranged in register plane-parallel to the first cuvette surfaces () and spaced apart by a distance (), thus forming, in the active position of the micro cuvette assembly (), one or more micro cuvettes () in which a liquid volume () applied previously to one of the cuvette surfaces () is held between these two cuvette surfaces (). The micro cuvette assembly () according to the present invention is characterized in that each of the first cuvette surfaces () of the first partial plate () is formed individually and completely in each case by a surface of a transparent body () which is accomplished as a free beam optical element and arranged in each case in an opening () penetrating the first partial plate (). Also disclosed is the use of this micro cuvette assembly () in the carrying-out of a method for examining biological samples.
