A filter strip and composite assemblies for filtering microliter quantities of fluids. A linear array of wells having open top and bottom ends are connected by frangible webs in spaced-apart relation with discrete filter membranes closing the bottom ends of each well. Tabs are provided on the ends of the filter strip for holding the same and supporting the strip in a rectangular holder having alpha-numeric designations for identifying each well in a plurality of such filter strips contained within the holder. The filter strip may be used in a vacuum manifold for applying a pressure differential across the filter membrane and directing the filtrate into an aligned aperture of a closed bottom well of an array of wells held within the manifold. Alternatively, the filter strip may be used with a transfer plate for directing the filtrate from each well of the filter strip to an aligned well of a closed bottom array of wells. Another composite assembly includes a pressure manifold for applying an increased pressure above the membranes.
