A portable motorized centrifugal system is optimized for low cost manufacture and operation. Separation of inhomogeneous fluid biological samples, such as liquid plasma from whole blood, is a common step in medical diagnostic tests. This system may enable remote separation where access to plug-in power sources are limited. The system may facilitate at-home testing. Due to biohazard concerns, the entire centrifugal apparatus portable and disposable, or the system includes one or more disposable elements within the interior of the centrifuge. Alternatively, the system may contain a module of higher value components that are re-usable after disinfection. Devices and methods for implementing centrifugal separation may include disk-shaped fluidic cartridges and tubes with reduced drag cross-section.

A centrifuge (1) for separating intermixed particulate material of different specific gravity. The centrifuge (1) comprising a centrifuge bowl (10) having a plurality of annular recesses (19), a housing (30), an inlet (17), and means for rotating the centrifuge bowl (10) about the central axis (15). An annular cavity (31) is defined between the housing (30) and the centrifuge bowl (10). The annular cavity (31) is fluidly connected to the plurality of annular recesses (19) on the inner surface of the centrifuge bowl by a number of perforations in the centrifuge bowl wall (12). The annular cavity (19) has a fluid inlet to provide fluid into the annular cavity. The annular cavity (19) has an accumulated cross-sectional flow area (Allow) at two different heights in the annular cavity that differs by at least a factor 10.
