Abstract
A method and filtering system are described. The filtering system comprises a vacuuming plate having a base with a plurality of outlet openings extending therethrough, a plurality of walls extending from the base to define a cavity, and a vacuum port in fluid communication with the cavity; and a filtering unit mounted to the vacuuming plate and enclosing the cavity. The filtering unit comprises a filter plate with a plurality of filter openings extending therethrough and aligned with the outlet openings; a filtering membrane extending across the filter plate and covering the plurality of filter openings; and a piercing plate on the filter plate maintaining the filtering membrane therebetween, the piercing plate having a plurality of vessel piercing members extending away from the filtering membrane, the vessel piercing members having conduits extending through the piercing plate, the conduits aligned with the filter openings to allow fluid flow therebetween.
