摘要： 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. In addition, each of the rotors has a central outer surface portion positioned between the upper and lower plates, wherein the central outer surface portion is outwardly bulged. The microcentrifuge further comprises a pulley and a drive belt that is operatively engaged with the pulley and the bulged central outer surface portion of each of the plurality of rotors.

摘要： The present invention provides for an improved method and apparatus for cleaning industrial lubricants used in industrial processes. The method comprises providing a centrifugal separator apparatus connected as a bypass or in-line filter in the lubricating or washing fluid tank. The apparatus includes a centrifugal separator having a casing and a rotor rotatably mounted in the casing. A centrifugal pump is provided between the tank and the inlet of the separator. A source of compressed air is provided connected to the casing of the separator. Some of the fluid from the tank is pumped by the centrifugal pump into the separator to cause the rotor to rotate at a speed sufficient to provide a rotational force of the fluid impinging on the casing of between about 1000 g and about 2000 g to thereby clean the fluid. The cleaned fluid is returned to the tank. The volume of air in the casing is maintained by introduction of air into the casing by the source of compressed air. A control panel is provided to monitor the operation of the separator and control the pump and source of compressed air to maintain rotational force of the separator within the range.

摘要： A flow-through microcentrifuge comprising a container in which a sample is placed, and a power source capable of rotating the container around an axis. High speed rotation causes the components of the sample to separate according to their respective densities. Pressurized gas, a flowing liquid, electromagnetism, or an engine can power rotation of the container. Due to the small size of the flow-through microcentrifuge, speeds can reach up to 600,000 rpm, with a corresponding increase in centrifugal acceleration up to 1,500,000 g. In addition to separation, the flow-through microcentrifuge can resuspend pelleted material in a liquid by rotating in one direction and then in the opposite direction, repeatedly. The flow-through microcentrifuge is also able to mix two or more reagents using this method. The flow-through microcentrifuge is modular in nature, meaning two or more can be placed together in any configuration and run by the same power source. In the preferred embodiment, several microcentrifuges are used simultaneously to centrifuge samples in multi-well plates.
