Abstract:
1. A microfluidic sample processing device 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 cover attached to the first major surface of the body, the first cover defining the vias, the outer channels, and the process chambers in connection with the first major surface of the body; a second cover attached to the second major surface of the body, the second 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 cover is located radially inwardly of an inner edge of the process chambers of the plurality of fluid structure, and wherein the inner edge of the second cover is located radially outwardly of 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 the second cover comprises a metal, and wherein the central cover is formed from one or more materials that are less thermally conductive than the second cover.
