Abstract
A fixed angle centrifuge rotor includes a rotor body having a circumferential sidewall and a plurality of circumferentially spaced tubular cavities. Each tubular cavity has an open end and a closed end, and is configured to receive a sample container therein. The rotor further includes a pressure plate operatively coupled to the rotor body so that the pressure plate, in combination with the plurality of tubular cavities and the circumferential sidewall of the rotor body, define a hollow chamber within the rotor. The rotor further includes a plurality of elongated torque transfer members supported by the rotor body and an annular containment groove.
Claims8
A fixed angle centrifuge rotor, comprising:
- a rotor body having a plurality of tubular cavities spaced circumferentially about a rotational axis of the rotor, each of the tubular cavities having an open end and a closed end, and each of the tubular cavities being configured to receive a sample container therein;
- and
- an annular containment groove disposed above and circumferentially surrounding the plurality of tubular cavities, the annular containment groove having an upper reentrant portion in which a profile of the groove curves from an arcuate back wall in a direction axially upward and then radially inward toward an upper apex region and then curves in a direction axially downward and radially inward toward an edge of the rotor body, wherein the annular containment groove, in combination with the upper reentrant portion, is configured to capture and retain stray material within the rotor during rotation of the rotor.
