Problem Addressed

Significant advances have been made in the design and fabrication of microreactors for use in lab-on-a-chip or plant-on-a-chip applications. However, less progress has been made in the fluidic and pumping technology used to move reactants into and out of microreactors. This has resulted in the overall performance of microchemical systems being limited by fluidic and pumping technology. Existing microfabricated valves and pumps are incompatible with harsh chemistries, limited to low flow rates and volumes, and produce fluctuating flows. Macroscale syringe pumps are capable of fluctuation-free flow, but impose a uniform flow rate across all connected devices, limiting their utility in microchemical systems where different flow rates are required. This invention describes a novel inline pumping technology that overcomes these limitations.
