Patent ID: 7959875

Claim:
A microfluidic device, comprising: a substrate having a plurality of channels disposed therein, each of the channels having an inlet end and an outlet end; at least one reagent reservoir of a type capable of holding a material; a plurality of outlet reservoirs coupled to respective outlet ends of the plurality of channels; at least one bi-directional diaphragm pump comprising at least three non-elastomeric membrane-based valve structures; a distribution valve disposed in fluid coupling with the at least one reagent reservoir and at least one of the inlet ends, wherein the distribution valve is adapted to controllably direct a flow of the material from the at least one reagent reservoir to a plurality of outlet reservoirs via at least one of the channels coupled to the distribution valve; and a cartridge adapted to detachably couple to the substrate and having the at least one reagent reservoir disposed thereon for porting the material into the plurality of channels disposed in the substrate.
