Abstract
A device for separating and isolating components of a biological fluid comprising a container for containing the fluid to be processed, a tube cap assembly for dosing the container while providing filling and extraction communication therewith, a float assembly disposed within the container for funneling and controlling biological fluid flow into an inverted domed shaped isolation chamber within the float and controlling the biological fluid flow out of the isolation chamber for effecting an encapsulation or a sealed isolation of at least one component or fraction of the biological fluid flow within the isolation chamber during a centrifugation process. The device further comprising a flexible tube for connecting an extraction passageway disposed within the float assembly and an extraction valve of the tube cap assembly for allowing extraction of at least the one component or fraction encapsulated or isolated within the chamber.
