Abstract
A method is provided for applying a fluid onto a surface of a solid substrate. The method employs a distribution member having an upper surface and a lower surface, and including a permeable portion having channels therethough. The distribution member is positioned such that the lower surface of the distribution member is in opposing relation to the surface of the substrate. Once the distribution member is in position, the fluid is dispensed onto the upper surface of the permeable portion of the distribution member such that the fluid penetrates the distribution member and is retained thereby. In addition, a distribution pressure differential is applied between the upper and lower surfaces without using mechanical means such as a squeegee so that a portion of the fluid passes through the channels of the permeable portion of the distribution member and onto the solid substrate surface. Other embodiments of the invention include an apparatus for carrying out the aforementioned method and a reagent application station for applying a plurality of reagents onto a surface of a solid substrate.
