Abstract: A laminated plate structure including conduit and regent delivery means for a fluid delivery system is provided to deliver precise volumes of a plurality of fluids in sequence to a treatment reservoir. Fluid channels are formed in the plate structure to provide a means for delivering fluids from a plurality of fluid reservoirs attached to the plate structure to one or a plurality of treatment reservoirs attached to the plate structure. Each fluid is delivered by a system comprising a fluid reservoir, an inlet valve in fluid communication with the fluid reservoir, a positive displacement pump in fluid communication with the inlet valve and an outlet valve in fluid communication with the positive displacement pump all of which are attached to the plate structure. The means for delivering fluid and the fluid reservoirs are positioned on opposing surfaces of the plate structure. The plate structure is provided with vent holes for venting vapors that may be produced during formation of the plate structure.

Abstract: A fluid delivery system is provided to deliver precise volumes of a plurality of fluid in sequence to one or more treatment reservoirs. Fluid channels are formed in a plate structure to provide a means for delivering fluids from a plurality of fluid reservoirs to one or a plurality of treatment reservoirs. Each fluid is delivered by a system comprising a pneumatically or electrically activated inlet valve in fluid communication with a fluid reservoir, a positive displacement pump in fluid communication with the inlet valve and a pneumatically or electrically activated outlet valve in fluid communication with the positive displacement pump.
