摘要： A flow substrate mounting structure comprising a fastener aperture and an alignment feature, wherein the alignment feature comprises at least one of an alignment pin removably coupled with the flow substrate mounting structure, an alignment slot, and an alignment step. A structure for coupling a plurality of flow substrates comprising a flow substrate mounting structure comprising a first fastener aperture, and a second fastener aperture, wherein the first fastener aperture is configured to couple with a first fastener and the second fastener aperture is configured to couple with a second fastener, wherein an alignment fixture is used to align the flow substrate mounting structure with the plurality of flow substrates.

摘要： A ring-shaped gasket for making high-purity fluid pathway connections between opposing fluid delivery apparatus elements having at least one simple flat surface in contact with the gasket. The face of at least one apparatus element typically has a circular counterbore depression to receive the gasket, but is not required. The gasket has a body, pierced through by a hole creating a fluid pathway and defining a radial inner surface, and additionally having a radial outer surface, a first axial end surface and a second axial end surface. At least one of the first and second axial end surfaces has a stress concentration feature radially adjacent to a gasket sealing region, the sealing region constructed to be in contact with a face surface of a corresponding fluid conduit port. The stress concentration feature may be a groove or a plurality of cavities disposed adjacent the gasket axial end surface sealing region.

摘要： A gasket retainer that is absent sharp corners, has apertures of reasonable dimensional tolerance, and may be conveniently made by a variety of manufacturing processes. The retainer is made from thin flat springy material that readily returns to form after slight bending. Representative gasket capturing apertures are of smoothly non-convex outline with major dimension sufficiently large to allow passage of a ring shaped gasket turned on edge and minor dimension sufficiently small to engage, on approximately opposite circular segments that each engage along less than one third of a gasket circumference, a cavity or groove on the outside diameter periphery of the gasket turned flat parallel to the retainer material sheet. Fasteners may be retained by similar apertures.
