Patent ID: 8605279

Claim:
A micro cuvette assembly ( 1 ) for examining biological samples, comprising a first partial plate ( 2 ) with one or more plane first cuvette surfaces ( 3 ) and a second partial plate ( 4 ) which is configured to be arranged relative to the first partial plate ( 2 ) and has at least one or more plane second cuvette surfaces ( 5 ) which, in an active position of the micro cuvette assembly ( 1 ), are arranged in register plane-parallel to the first cuvette surfaces ( 3 ) and spaced apart therefrom by a distance ( 6 ), thus forming in the active position of the micro cuvette assembly ( 1 ) one or more micro cuvettes ( 7 ) in which a liquid volume ( 8 ) applied previously to one of the cuvette surfaces ( 3 , 5 ) is held between these two cuvette surfaces ( 3 , 5 ) such that the two cuvette surfaces ( 3 , 5 ) are wetted by the liquid volume ( 8 ), wherein each of the first cuvette surfaces ( 3 ) of the first partial plate ( 2 ) is formed individually and completely in each case by a surface of a transparent body ( 10 ) which is of a different material than the first partial plate ( 2 ) and which is configured as a free beam optical element and arranged in each case in an opening ( 9 ) that completely penetrates the first partial plate ( 2 ); wherein the cuvette surfaces ( 3 ) of the transparent bodies ( 10 ) protrude by an overhang dimension ( 15 ) beyond first surfaces ( 16 ) of the first partial plate ( 2 ) that adjoin said cuvette surfaces ( 3 ); and wherein the transparent bodies ( 10 ) are mounted in the first partial plate ( 2 ) in such a way that a back side ( 14 ) of the transparent bodies ( 10 ) is located inside of the first partial plate ( 2 ) and offset from a second surface ( 19 ) of the first partial plate ( 2 ) by a set-back dimension ( 18 ).
