ABSTRACT:
A test tube (72, 72′) defines a test tube axis (75) and contains or supports an associated sample in an annular sampling region (12). At least two alignment bearings (80, 81, 81′, 82, 83, 110, 140, 142, 181, 182, 183, 184, 211, 212) engage the test tube at opposite sides of the annular sampling region along the test tube axis. At least one bias bearing (86, 86′, 87, 140, 142, 204) is radially spaced apart from the at least two alignment bearings and presses the test tube against the at least two alignment bearings to align a portion of the annular sampling region respective to the at least two alignment bearings. A motor (112) engages the test tube to selectively rotate the test tube.
