<p>The present invention relates generally to a fractionator (100) for collecting at least one of a plurality of segregated components from a segregated sample disposed in a sample tube (200). The fractionator (100) has a head (100) with a head surface (115) at its forward end. The head (110) may be configured to form a slideable seal with the inside surface of the sample tube (200). A collection port (130) is disposed forward of the head surface (115), and a fluid passageway (135) is in fluid communication with the collection port (130) and is configured and arranged to allow fluid transport from the sample tube (200) to a sample receptacle (230). The fractionator (100) may have a valve (330) in fluid communication with the collection port (130) and may have a valve controller (350) configured and arranged to operate the valve (330) based on the location of the collection port (130) with respect to a sample in the tube (200).</p> |
