Abstract:
1. A microfluidic sample processing disk comprising: a body comprising first and second major surfaces; a plurality of fluid structures, wherein each fluid structure of the plurality of fluid structures comprises: a first annular cover attached to the first major surface of the body, the first annular cover defining the vias, the outer channels, and the process chambers in connection with the first major surface of the body; a second annular cover attached to the second major surface of the body, the second annular cover defining the process chambers of the plurality of fluid structures in connection with the second major surface of the body, wherein an inner edge of the second annular cover is located radially outward of the annular ring defined by the vias of the plurality of fluid structures; and a central cover attached to the second major surface of the body, the central cover defining the inner channels and the vias in connection with the second major surface of the body, wherein an outer edge of the central cover is located radially outward of the annular ring defined by the vias of the plurality of fluid structures.
