Abstract: Apparatus for treating samples comprising a sample holding element; a wash trough removably positioned over the sample holding element; transfer tubes or conduits in sample receiving contact with the sample holding element, extending through the wash trough to a transfer head positioned over a vacuum manifold which elements, in combination, deliver sample from the sample holding element directly to a plurality of filter discs in said vacuum manifold means. A cutter block is positioned between the transfer head and manifold. The apparatus is designed and arranged so that the cutter block will simultaneously cut and position a plurality of filter paper discs on said filter discs. A plurality of individual samples can be treated rapidly while minimizing the amount of filter paper used with assurance of quantitative sample transfer.
