    Abstract: A cuvette adapted to contain spherical particles having a specific binding agent on the surface thereof and which have a detectably different light scattering characteristic in the presence of a material having a specific binding partner therefor, and which includes a window through which light can be projected for the purpose of determining any change in light scattering properties of the contents of the cuvette, and an optical element occupying at least part of a wall of the cuvette which, when light passes theretrough, causes at least some of the light to be deflected off axis towards a particular point. By using such a cuvette in combination with a light level detector located as the said particular point, a cuvette can be identified before an assay is performed by checking the light level at the said particular point. The optical element may be a hologram or a diffraction grating or a lens or any combination thereof. A method of checking whether a cuvette inserted into a testing apparatus, includes such an optical element is described as well as a method of performing an assay which includes a cuvette validating step.

    Abstract: A cuvette (10) suitable for use with photometric blood testing apparatus and the like. The cuvette (10) includes a receptacle having flanges (30) which are flexible to enhance the positioning of the cuvette. Single and dual cuvette embodiments are described. The invention additionally includes means for encoding a cuvette (10) for optical detection thereof by means of multiple facets (34) which reflect light passing therethrough molded integrally in the flanges (30).
