The present invention relates to an apparatus for delivering a substance (e.g. a liquid solvent or reagent) onto a substrate. The apparatus comprises a plurality of elongated conduits disposed in fixed, spaced relation in a common support structure, wherein each of said conduits having a large opening at one end and a small opening at its other end. The large openings are disposed in an array along one side of said support structure, and the small openings are disposed in an array along an opposite side of said support structure. The large-opening array is arranged with a center-to-center pitch larger than that of the small-opening array; and a region of each conduit extending from a respective one of said small openings is of capillary size, such that a liquid placed in contact with said small-opening array can be drawn at least partially into said conduits by way of capillary action. Furthermore, a method for simultaneously transferring a plurality of submillimeter beads from one location to another location is described.
