A filtration method and associated apparatus are disclosed for improving the separation yield of matrix based compositions. The method includes the steps of positioning a matrix based composition that includes at least some liquid in a filter vessel and applying a moderate over-pressure to the composition upstream of the filter to accelerate the movement of liquid through the filter. The associated apparatus includes a funnel support, a funnel resting in the funnel support, a filter cup resting in the funnel opposite the funnel support, an over-pressure cap for engaging the filter cup opposite the funnel, and a source of pressurized gas in communication with the over-pressure cap for supplying a moderate over pressure to the filter cup for accelerating the movement of solvent through the filter cup and the funnel.
