1. An apparatus for capturing a desired quantity of material from a sample suspension on a filter for deposition on a receiving surface, comprising a filter, a member to support said filter, means for providing a pressure to cause said sample suspension to flow through said filter, means for sensing said pressure across said filter so as to determine the flow rate of said sample suspension through said filter, thereby indicating the amount of material captured on said filter, means for adjusting said flow rate of said sample suspension through said filter, and a receiving surface which receives said captured material from said filter.
