Apparatus, system, and method for collecting a target material

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;
• and
• a 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.
