Claims17
A microfluidic device comprising:
- a) an annular body having a top surface, a bottom surface, an inner surface defining an aperture, and a concave wall extending downward from the bottom surface to a base, the annular body comprising an input port and an output port disposed therein;
- b) an elastic collar fixedly attached to the bottom surface of the annular body, the elastic collar comprising a flange disposed around the periphery thereof and a bottom surface fixedly attached to the base of the annular body, wherein the flange is configured to be mated to the bottom surface of the annular body;
- and
- c) a rigid substrate having a top surface, a bottom surface fixedly attached to the top surface of the annular body, and a tapered extension positioned within the aperture and extending across the elastic collar to form a channel with the elastic collar that is accessible by the input port and output port and that compresses inward towards the tapered extension, the rigid substrate comprising an inlet and an outlet disposed in the top surface and positioned in alignment with input port and output port of the annular body.
