Abstract:
1. A centrifuge for selectively concentrating and collecting constituents of a biologic liquid mixture, said constituents having differing specific gravities and being stratifiable in a centrifugal field produced by said centrifuge, said centrifuge comprising: a) a chamber arranged to contain a liquid mixture and having a central longitudinal axis about which said chamber is arranged to be rotated to produce said centrifugal field, said chamber comprising: b) a motor to rotate said chamber about said central longitudinal axis to produce said centrifugal field, whereupon said constituents of said biologic liquid mixture in said chamber stratify into at least two concentric stratified constituent layers as a function of the differing specific gravities of said constituents, said at least two concentric stratified constituent layers forming an interface between immediately adjacent constituent layers thereof, said interface being visible through said transparent side wall, and wherein a first of said at least two concentric stratified constituent layers is present at said first port, said first port being selectively openable to enable at least a portion of said first of said at least two concentric stratified constituent layers to be automatically ejected from said chamber through said first port as a result of pressure built up by said centrifugal field; and c) an actuatable member arranged to be actuated in response to the observation of said interface to close said first port.
