Abstract
A multicuvette rotor assembly for use in a clinical chemistry analyzer of the centrifugal type includes a body member that defines a circumferential array of spaced radially extending recesses, with a divider member in each recess to define a first chamber and a second chamber radial outward from said first chamber; and a ring member that has a mating reference surface seated on an annular reference surface of the body member, with the inner peripheral surface of the ring member located outwardly of the middle of the second chambers. A circumferential array of first optical windows is bonded to the ring member, the lower surface of each first optical window being parallel to the mating reference surface; and a circumferential array of second optical windows is bonded to the base of the body member in alignment with the first optical windows such that each pair of opposed aligned surfaces of corresponding first and second optical windows are parallel to one another and define an optical path of precise and stable path length. A cover member has sealing surfaces that mate with the edges of the recesses of the base member and the inner peripheral lip of the ring member to provide a co…
