Abstract
A funnel element having an open end and a closed pointed end configured to receive a multi-component fluid containing a solid fraction. The solid fraction can comprise cellular material that sediments toward the closed pointed end to form a cell pack. A wash fluid can be pumped through the cell pack to entrain microparticles and soluble contaminants. The wash fluid can be introduced into the funnel element below the cell pack such that the wash fluid percolates through the cell pack. The percolating wash fluid can dislodge microparticles or other contaminants trapped within the cell pack. Additional wash fluids can be added to funnel element where excess wash fluids overflow from the funnel element through the open end of the funnel element.
