APPARATUS, SYSTEM, AND METHOD FOR COLLECTING A TARGET MATERIAL

摘要

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 at a first end of the collector and a funnel at a second end that that is in fluid communication with the cannula. The chamber is sized and shaped to hold the processing receptacle. In another implementation, the processing receptacle may be inserted into a bore within the collector.

1. A method for collecting a target material from a sample, the method comprising the steps of:
adding a fraction-density-altering solution to a vessel that contains the sample, the fraction-density-altering solution to change the density of a first fraction of the sample such that the density of the target material is less than a changed density of the first fraction; inserting a collector that includes a first processing receptacle into an open end of the vessel; and centrifuging the vessel and the collection system to force at least a first portion of the target material into the first processing receptacle.
