Abstract
A plate structure including conduit and reagent 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 check valve in fluid communication with a fluid reservoirs, a positive displacement pump in fluid communication with the check valve and an injector in fluid communication with the positive displacement pump all of which are attached to the plate structure. A partition switch attached to the plate structure is provided to direct fluid to the desired treatment reservoirs or pressure reservoirs.
