Abstract

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 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 check valve in fluid communication with a fluid reservoir, a positive displacement pump in fluid communication with the check valve and an injector in fluid communication with the positive displacement pump. A partition valve is provided to direct fluid to the desired treatment reservoirs.
