APPARATUS, SYSTEM, AND METHOD FOR COLLECTING A TARGET MATERIAL

摘要

This disclosure is directed to an apparatus, system and method for retrieving target material from a suspension. A system includes a processing vessel, such as an Eppendorf tube, a syringe or a test tube, and a collector. The collector is sized and shaped to fit into a primary vessel, such as a test tube. The collector funnels the target material from the suspension through a cannula and into the processing vessel. The cannula extends into a cavity at a first end of the collector that holds the processing vessel. The collector includes a concave opening at a second end in fluid communication with the cannula. In one implementation, the processing vessel includes at least one displacement fluid to be expelled, such that the at least one displacement fluid pushes the target material into the collector.

主权项

1. A method for collecting target material from a sample, the method comprising the steps of
inserting a collector into an open end of a primary vessel that contains the suspension; inserting an nth processing vessel into a cavity within the collector, adding an nth displacement fluid to the nth processing vessel, the nth displacement fluid having a density greater than an nth sub-fraction of a fraction of the sample, the nth sub-fraction including at least a portion of the target material; and centrifuging the primary vessel, the collector, and the nth processing vessel, the nth displacement fluid to flow into the primary vessel via the collector to displace the nth sub-fraction from the primary vessel into the nth processing vessel via the collector.
