Abstract
An automatic chemistry analyzer includes sample cups circumferentially located on a sample wheel. Means moves the sample cups rotationally under cycloidal action to and away from a target location where a probe operates vertically in relation to the sample cups and an injection cell. The motion is effected by a cam operating with a cam follower formed by lobes circumferentially located about a drive wheel which houses the sample wheel or carousel.
