Abstract:
A device for processing sample material, the device comprising:a substrate comprising first and second major surfaces and a hub defining an axis of rotation for the substrate; a plurality of electrophoresis channels in the device, wherein the plurality of electrophoresis channels extend generally radially outward relative to the axis of rotation; a plurality of process chambers in the device, each of the process chambers defining a volume for containing sample material; a connection structure located between at least one electrophoresis channel of the plurality of electrophoresis channels and at least one process chamber of the plurality of process chambers, wherein the connection structure comprises a closed configuration in which sample material is prevented from moving into the at least one electrophoresis channel from the at least one process chamber, and wherein the connection structure comprises an open configuration in which sample material is capable of moving into the at least one electrophoresis channel from the at least one process chamber; and at least one electrophoresis medium chamber in fluid communication with each electrophoresis channel of the plurality of electrophoresis channels.
