Abstract: A centrifuge apparatus for use in the analysis of laboratory samples. The centrifuge apparatus includes a plurality of individual centrifuge devices and a robotic loading and/or unloading device. Each of the centrifuge devices may be loaded and unloaded without affecting the operation of the other centrifuge devices. The centrifuge devices include a plurality of rotors that are spaced apart and translated along a predetermined path. The rotors are rotatably mounted with respect to the predetermined path and the rotational planes of the rotors extend substantially at right angles to the predetermined path.
