Abstract
A centrifuge rotor includes a rotor body having a base, a sidewall, and a top. The top defines an opening that provides access to an annulus cavity inside the rotor body. A cover is removably attachable to the rotor body to seal the annulus cavity. A drive hub extends from a portion of the base of the rotor body and couples to a drive shaft of a centrifuge motor. The rotor body is sized to receive one or more sample containers in the annulus cavity, and to constrain the one or more sample containers inside the annulus cavity between the base, the sidewall, and the top when the one or more containers are advanced radially against the sidewall.
Claims17
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.
A centrifuge rotor comprising:
- a rotor body, including a sidewall;
- an annulus cavity inside the rotor body;
- a first container constrained inside the annulus cavity, the first container having a wedge shape and being constrained by at least the sidewall;
- and
- a second container constrained inside the annulus cavity, the second container having a substantially rectangular shape and being constrained by at least the sidewall.
