Claim Text:
1. A method for separation of a heterogeneous fluid sample having constituents of differing density, the method including the steps of: identifying a centrifuge vessel with a housing including a floor and a side wall extending up from the floor; at least two chambers including a lower chamber and an upper chamber, the lower chamber closer to the floor than the upper chamber; a divider wall interposed between the upper chamber and the lower chamber; a spillway around the divider wall, the spillway joining the upper chamber to the lower chamber; and an outlet comprising a conduit that extends from the lower chamber through the divider wall and out of the housing, such that a constituent of the heterogeneous fluid sample within the lower chamber can be removed from the lower chamber; inputting the heterogeneous fluid sample with constituents of differing densities into the vessel of said identifying step; centrifuging the vessel with gee forces oriented substantially toward the floor until the heterogeneous fluid sample is separated into at least two differing density fluids including a higher density phase and a lower density phase; and extracting the higher density phase from the lower chamber through the outlet.
