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 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 funnel 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.

1. A method for collecting a target material from a suspension, the method comprising the steps of:
inserting a collector into an open end of a primary vessel that contains the suspension, the collector comprising:
a main body having a first end and an opposing second end to fit within the open end of the primary vessel, the second end having a concave opening that narrows to an apex within the collector and the first end having a cavity; anda cannula that extends from the apex into the cavity, the cannula to provide an opening between the concave opening and the cavity; inserting a processing vessel into the cavity, the processing vessel to be punctured by the cannula adding a displacement fluid to the processing vessel, the displacement fluid having a density greater than the density of the target material; and centrifuging the primary vessel, the collector, the displacement fluid, and the processing vessel, wherein during centrifuging, the displacement fluid flows into the primary vessel via the collector to displace the target material from the primary vessel into the processing vessel through the collector via the cannula.
