Abstract
The present invention relates to methods, devices and systems for separation and concentration of particles from liquid and fluid samples. In some embodiments, the separation/concentration is achieved by sequential centrifugation steps. In particular, one aspect of the invention relates to a separation/concentration device which comprises at least a first chamber () and a second chamber () connected by a first valve (), whereby operation of the first valve controls the material transfer from the first chamber to the second chamber. In some embodiments, valve operation can be manually, semi-manually or automatically. Other aspects of the invention relate to single- or multi-chambered separation/concentrator devices, and methods and systems for use. Other aspects of the invention relate to devices for operation of the valves, e.g., semi-manual actuation devices, and automatic inertial activation devices and mechanical actuation devices present in purpose-built centrifuges.
