Abstract:
1. An apparatus for centrifugally loading and thermally cycling a sample disk, comprising: a sample disk having a plurality of first sample chambers, a plurality of second sample chambers, and a reservoir for storing a volume of liquid sample, each second sample chamber in fluid communication with a respective first sample chamber, means for centrifugally loading the plurality of first sample chambers with liquid sample upon rotation of the sample disk about a rotational axis of the sample disk, and comprising a plurality of circumferential fill conduits positioned circumferentially around the sample disk, each circumferential fill conduit being positioned between a respective pair of adjacent first sample chambers of the plurality of first sample chambers, the circumferential fill conduits in fluid communication with the reservoir to permit transfer of the liquid sample from the reservoir to the plurality of first sample chambers, means for centrifugally loading the plurality of first sample chambers with a biological material from the plurality of second sample chambers; and means for thermally cycling the plurality of first sample chambers of the sample disk.
