ABSTRACT:
An improved method and apparatus are disclosed for sealing the outlet port of a flexible blood-processing bag after a separated first blood component has been expressed therefrom. The improvements relate to the use of a valve contained within the flexible blood-processing bag and responsive to the difference in specific gravities between first blood component and second blood component. For example, the valve may comprise a stopper ball having a specific gravity which allows it to float at the interface between first and second blood component.
