The invention relates to a cuvette (10; 20; 30; 40; 50) having at least one sealing element (16; 26; 36; 46) and two transparent elements (11, 12; 21, 22; 41, 42), the latter being disposed at a distance from one another and defining opposite limiting surfaces of a sample channel (15; 25; 45) and the sealing element defining side walls of the sample channel, which is thus formed as a channel thatis closed in the longitudinal direction having an inlet opening (10a) and an outlet opening (10b). At least one distancing piece (13; 23; 33; 43; 53) is provided that holds the transparent elements (11, 12; 21, 22; 41, 42) at a distance from one another. At least one of the two transparent elements (11, 12; 21, 22; 41, 42) has a shoulder (11a, 12a; 21a, 22a; 41a, 42a) extending in the direction of the other transparent element and forming a limiting surface of the sample channel (15; 25; 45), such that the height (h5) of the sample channel is less than the height (h6) of the at least once distancing piece.
