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 that is 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.
Cuvette (10; 20; 30; 40; 50), comprenant au moins un élément d'étanchéité (16; 26; 36; 46) et deux éléments transparents (11, 12; 21, 22; 41, 42), ces derniers étant disposés à distance entre eux, et définissant deux surfaces opposées de limitation d'un canal de prélèvement (15; 25; 45), l'élément d'étanchéité définissant les parois latérales du canal de prélèvement, lequel se présente ainsi sous la forme d'un canal fermé, comportant une ouverture d'entrée (10a) et une ouverture de sortie (10b). Il est prévu au moins un écarteur (13; 23; 33; 43; 53) qui maintient les éléments transparents (11, 12; 21, 22; 41, 42) à distance entre eux. Au moins l'un des deux éléments transparents (11, 12; 21, 22; 41, 42) présente un épaulement (11a, 12a; 21a, 22a; 41a, 42a), qui s'étend en direction de l'autre élément transparent et forme une surface de délimitation du canal de prélèvement (15; 25; 45), de telle façon que la hauteur (h5) du canal de prélèvement soit inférieure à la hauteur (h6) d'au moins un écarteur.
