Select a piece of coarse or medium porosity filter paper that fits flat on the perforated floor of the funnel so that all of the holes are covered. Optimum filtration performance is achieved by the appropriate selection of filter paper porosity, by proper folding and positioning of the filter paper, and by following a few simple technique guidelines described below: Vacuum filtration of crystalline precipitates has the advantage of increased speed over gravity filtration because of the greater pressure differential between the top surface of the liquid and the bottom side of the filter paper or glass frit provided by the vacuum. While filtration is an important separation technique in a laboratory, it's also common in everyday life. Unfortunately I do not have access to liquid nitrogen, dry ice, etc. action background bass beat club commercial dance drive.
