1. A centrifuge rotor comprising:
a rotor body having a base, a sidewall, and a top, the top defining an opening that provides access to an annulus cavity inside the rotor body;
a drive hub extending from a portion of the base of the rotor body and configured to couple to a drive shaft of a centrifuge motor; and
wherein the rotor body is configured to receive a first container in the annulus cavity, and to constrain the first container inside the annulus cavity between the base, the sidewall, and the top when the first container is advanced radially against the sidewall;
wherein the annulus cavity is shaped to constrain the first container and a second container, wherein the first container and the second container are different; and
wherein a plurality of first containers and a plurality of second containers are shaped and positioned to form an annulus within the annulus cavity.
