1. A centrifuge tube assembly for separating and aspirating constituent components of a fluid biological product, said assembly comprising:

  • a receptacle having an interior chamber for receiving a fluid biological product therein, said receptacle having a lower end and a side wall that extends upwardly from lower end;

    a cap for engaging said side wall and extending across an upper end of said receptacle;

    a common inlet and outlet port formed in said cap for respectively introducing the fluid biological product into said chamber and aspirating the constituent components from said chamber;

    a vent formed through said lower end of said receptacle; and

    a liquid impermeable piston mounted within said chamber and being slidable through said chamber while maintaining sealing engagement with an interior surface of said side wall of said receptacle;

    the fluid biological product being introduced through said common port into a region of said chamber between said piston and said upper end of said receptacle and said receptacle being centrifuged to separate the fluid product into constituent components thereof, which components are disposed in respective fluid layers in said chamber, whereby one or more of the fluid layers may be aspirated through said common port, said vent neutralizing pressure within said receptacle chamber as fluid is introduced into said chamber and as constituent components aspirated from said chamber.
