Abstract: The present invention is directed to a microcentrifuge apparatus adapted to simultaneously spin a plurality of samples contained within a plurality of rotors. The microcentrifuge comprises an upper plate that has a plurality of upper plate holes; and a lower plate that has a plurality of lower plate holes or recesses. The lower plate is adjacent and substantially parallel to the upper plate, and the plurality of lower plate holes or recesses are in axial alignment with the plurality of upper plate holes. The plurality of rotors are adapted for retaining and spinning the plurality of samples, and are positioned between the upper plate and the lower plate. Each of the plurality of rotors has at opposing ends an upper shaft and a lower shaft, wherein the upper shaft engages one of the upper plate holes and the lower shaft engages one of the lower plate holes or recesses such that the axes of rotation of each of the plurality rotors are substantially perpendicular to the upper and lower plates.

Abstract: A microcentrifuge apparatus has a plurality of rotors for simultaneously spinning a plurality of samples; a retainer for retaining each of the rotors on a bearing surface; and at least one source of motive power, coupled to the rotors by a coupling means, for causing each of the rotors to spin at substantially the same rate. The source of motive power can be a motor, engine, or electromagnetic power. The coupling means can be a drive belt, gears, or friction drive. Another embodiment of the microcentrifuge has a plurality of disposable rotors for simultaneously spinning a plurality of samples; a retainer for retaining each of the rotors on a bearing surface; and a source of motive power, coupled to the rotors, causing each of the rotors to spin at substantially the same rate.
