Abstract:
A microfluidic valve comprising:a) a stator chip defining at least one inlet and at least one outlet therein, wherein the stator chip comprises a first planar substrate and a second planar substrate having facing contract surfaces sealably secured together, wherein the first planar substrate defines a first portion for each of the at least one inlet and for each of the at least one outlet, and the second planar substrate defines a second portion for each of the at least one inlet and each of the at least one outlet; and b) a rotor sealably engaging the stator chip, the rotor defining at least one rotor channel therein, said rotor being rotatable between a closed position preventing fluid communication between at least one inlet and at least one outlet, and an open position where at least one rotor channel is in fluid communication with at least one inlet and at least one outlet.
