  • Patent number: 5924972
    Abstract: A portable eccentric centrifuge for the separation of compound fluid samples in areas where an external power source is not easily accessible and while being supported upon on a non-level surface. The portable eccentric centrifuge includes a compact, lightweight base plate supported by a plurality of adjustable legs connected height adjustment assembly for static leveling of the centrifuge. At least one level indicator permits adjustment along multiple axes for aligning the base plate in the horizontal plane. A lightweight, compact, lidded chamber secured to the base plate houses the d.c. motor driven centrifuge. A timer controls the length of the centrifuge operation. A d.c. power adaptor permits operation where a 12 volt d.c. power supply is available, such as from a vehicle's cigarette lighter receptacle.
