Abstract:
1. Sample mixing structure on a sample processing device, the sample processing device adapted to rotate about an axis of rotation, the sample mixing structure comprising: a process chamber comprising a delivery port on a proximal side of the process chamber and a valve on a distal side of the process chamber, wherein the proximal side of the process chamber is located closer to the axis of rotation than the distal side of the process chamber; and a mixing chamber comprising a mixing port and a distal side, wherein the mixing port is located on the distal side of the process chamber, and wherein the distal side of the mixing chamber is located no further from the axis of rotation than the distal side of the process chamber; wherein rotation of the sample processing device about the axis of rotation moves at least a portion of sample material in the process chamber into the mixing chamber through the mixing port when the mixing port is open; and wherein, when the valve of the process chamber is open, rotation of the sample processing device about the axis of rotation moves the sample material out of the process chamber and the mixing chamber.
