Abstract

For rapid filtering on filter paper, the attachment fits into the funnel and has a network of ribs or cords in relief, and is fixed or removable. The network runs in the direction of liquid flow and separates the filter from the walls of the funnel while providing enough contact points to prevent tearing of the paper. It can be moulded or injection moulded from synthetics.
