A conveyor track drive includes a continuous loop conveyor for supporting and carrying a specimen container, with one portion of the conveyor extending through a drive housing. The conveyor includes a first segment extending through the housing, which then wraps around a portion of a drive sprocket, extends back upstream and around a portion of an idler sprocket and then includes a second segment transversely adjacent the first segment. A guide plate on the housing is positioned over the adjacent segments of the conveyor with a slot located to guide a specimen carrier from the first segment to the second segment. The specimen carrier then exits the housing on the second segment of the conveyor. A motor in the housing drives the drive sprocket to move the conveyor.
