Patent ID: 7771580

Claim:
A particle extraction system for use with a particle concentrator, having a fluid flow chamber, which concentrates particles, the particle extraction system comprising: a concentrate reservoir configured to hold 1.5 milliliters or less of fluid in which particles are concentrated, the concentrate reservoir in selective operative communication with the particle concentrator; a valve mechanism configured and positioned to provide the selective operative communication between the particle concentrator and the concentrate reservoir; and an extraction arrangement configured and positioned to extract the particles from the concentrate reservoir wherein the extraction arrangement includes, a fluid path which extends between the concentrate reservoir and a flushing port, and a multi-positional sample capture reservoir filled with a filling substance which does not dilute or allow dilution of the concentrated sample, and positioned at least partially within the fluid path, wherein the multi-positions of the sample capture reservoir include a position during a particle concentration mode and a different position during a particle extraction mode.
