Claims8
A method for obtaining a desired component of a physiological fluid that has been separated from a remaining components of said physiological fluid that are more dense than said desired component, comprising the steps of placing said physiological fluid and a floating separator disk in a chamber, separating said desired component from said remaining components of said fluid by centrifugation, and removing said desired component from said chamber, wherein said separator disk is configured to position itself automatically such that its upper surface is just below an interface between said desired component and said remaining components of said physiological fluid such that a small layer of said remaining components forms on said upper surface.
