Abstract
A cuvette for use in an optical instrument which includes a linear drive mechanism formed of a lead screw for positioning the cuvette along a linear path in the instrument. The cuvette has a body including at least one reaction well and an engaging feature for operatively engaging the threads of the lead screw so that the cuvette can be positioned along the linear path of the instrument. Preferably the reaction well of the cuvette has a trapezoid-shape cross section in a plane parallel to the optical path of the instrument in order to maximize the optical viewing area.
