Centrifugation

[thewax]

Note: This is not a homework question. This is part of a study effort for an upcoming test.

In a centrifuge, do the tubes spin around their own centers as well as spinning around the centrifuge's axis (like the Earth spins around the earth's own center and the sun) or do the tubes simply spin around the centrifuge's axis???????????????

The progress I made: My textbooks hardly even mention it and when I googled it, I couldn't find anything pertinent to my question.

Only around the spindle axis of the centrifuge. What would be the advantage of doing both?
