A cuvette arrangement for use in a chemical analysis system, which cuvette arrangement comprises an integrally constructed unit which defines separate chambers, for the receipt of sample-reagent mixtures. In order to overcome difficulties which arise in the use of the cuvette arrangement, and to reduce the manufacturing costs thereof, it is formed as a cuvette ring segment which possesses means for positioning it in the analysis system, each chamber possessing the following elements: an open and a closed end, an outer side wall forming an outer edge which fits into a first arc, an inner side wall forming an inner edge which fits into a second arc concentric with the first arc, a bottom wall extending between the outer and inner side walls at the closed end of the chamber, and windows which enable radiation energy to be transmitted through the chamber with low loss and free from distortion, which windows comprise a pair of flat, mutually parallel parts which are separated from one another by a defined distance, one of the flat parts in each pair being integrated with the outer side wall and the other of the flat parts in each pair being integrated with the outer side wall and the other of the flat parts in each pair being integrated with the inner side wall.

A cuvette arrangement for use in a chemical analysis system, which cuvette arrangement comprises an integrally formed, partially annular unit which defines a plurality of chambers for the receipt of sample-reagent mixtures, wherein each chamber includes the following elements: (a) an open and a closed end, (b) an outer side wall forming an outer edge which fits into a first arc, (c) an inner side wall forming an inner edge which fits into a second arc concentric with the first arc, (d) a bottom wall extending between the outer and inner side walls at the closed end of the chamber, and (e) windows which enable radiation energy to be transmitted through the chamber with low loss and free from distortion, which windows comprise a pair of flat, mutually parallel parts which are separated from one another by a defined distance, one of the flat parts in each pair being integrated with the outer side wall and the other of the flat parts in each pair being integrated with the inner side wall, said annular unit also including means for positioning it in the chemical analysis system, which positioning means comprises the following elements: (f) a lip which is integrated with the inner side walls and extends radially from the latter on the outside of the chambers, and (g) a projection which extends from the outside of the bottom wall of at least one of the chambers and along the longitudinal axis of the chamber.
