Abstract

A system for processing a plurality of solid supports comprises a tubular member having a proximal end, a distal end, and a lumen terminating at the distal end. A stop is positioned within the lumen at a location spaced about the distal end and is sized to permit fluids to pass through the lumen while preventing the passage of solid supports. A fluid transfer device is configured to transfer fluids through the lumen such that when a fluid containing one or more solid supports is aspirated into the lumen, a solid support may be drawn into the lumen to lodge against the stop.
