Microfluidic valve and method of manufacturing same

A microfluidic valve comprising:

• a) a stator chip defining an inlet and an outlet therein;
• and
• b) a second chip sealably engaging the stator chip, the second chip defining a valve channel therein, the second chip being movable between a closed position preventing fluid communication between the inlet and the outlet, and an open position where the valve channel is in fluid communication with the inlet and the outlet.

A method of manufacturing a stator chip for a microfluidic rotary valve, the method comprising the steps of:

• a) forming at least one first inlet channel and at least one first outlet channel in a first planar stator substrate;
• b) forming at least one second inlet channel and at least one second outlet channel in a second planar stator substrate;
• c) sealably securing the first stator substrate to the second stator substrate, such that the at least one first inlet channel is in fluid communication with the at least one second inlet channel and the at least one first outlet channel is in fluid communication with the at least one second outlet channel.
