Abstract
Abstract An arrangement for conveying receptacle holders along a predetermined path to different treatment stations in an automatic analyzing apparatus includes a location along the path wherein a predetermined rotation is imparted to the holder. The arrangement preferably comprises a pair of L-shaped slide bars located on opposite sides of the path of travel which support the holders and prevent rotation thereof except in a location where the side walls of the bars are recessed. Cooperating gearing on the holder and on one of the slide bars provides rotation of the holder as the holder is conveyed along the path.
