Curvette of generally circular form having apertures adjacent the outer periphery and having a plurality of compartment elements formed of an optically-clear plastic snugly locked in the apertures.

DETAILED DESCRIPTION In general, the present invention consists of a cuvette for use in chemical analysis, the cuvette having a main body with a central bore to permit mounting for rotation about the axis of the bore.
A flange extends radially outwardly in a general plane perpendicular to the axis of the bore, the flange being formed with a plurality of apertures located at equal spacing about the axis.
A plurality of compartment elements are formed of an optically-clear polymer, each element being in the form of an upwardly-opening container whose surface around the upper edge fits snugly in an aperture in the flange.
More specifically, the compartment element is provided with an outwardly-extending ridge that rests on the surface of the flange along the edge of the aperture.
At least one abutment such as a pair of buttons are located on opposite portions of the aperture to lock the compartment element in an aperture and to resist dislodgement therefrom.
