This disclosure is directed to an apparatus, system and method for retrieving a target material from a sample. A fraction-density-altering solution may be added to a vessel that contains the sample to change the density of a first fraction of the sample without changing the density of the target material or the density of any other sample fraction. A collector may be inserted into the vessel to funnel the target material from the sample into the collector or into a processing receptacle included in the collector. In one implementation, the collector may include a cannula which extends into a chamber to hold the processing receptacle at a first end of the collector and a funnel at a second end that that is in fluid communication with the cannula. In another implementation, the processing receptacle may be inserted into a bore within the collector. |
