Method and device for separately collecting components of a liquid by means of a centrifugal rotor

A device for separately collecting components of a liquid, comprising:

• a rotor;
• a first aspirator mounted on said rotor for rotation therewith, having a radially extending smaller diameter pipe, a radially extending larger diameter pipe disposed radially outwardly from the smaller diameter pipe, and first connecting means for connecting the smaller diameter pipe and the larger diameter pipe;
• a first container mounted on said rotor for rotation therewith;
• a first pipe communicating between said first container and said first connecting means, wherein fluid introduced into said first aspirator is subjected to increasing centrifugal force as it flows radially outwardly for creating suction at said connecting means and thereby in said first pipe;
• and
• means for independently introducing liquids into said first aspirator and into said first container, wherein liquid may be selectively introduced into said first container for centrifuging, and wherein liquid in said first container may be selectively withdrawn through said first pipe by introducing liquid into said first aspirator.
