Patent ID: 10086383

Abstract:
A fixed angle centrifuge rotor includes a rotor body having a circumferential sidewall and a plurality of circumferentially spaced tubular cavities. An annular containment groove is disposed above and circumferentially surrounds the 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 pressure plate includes circumferentially spaced upstanding tabs that are received in respective pockets located between adjacent tubular cavities. The rotor further includes a plurality of elongated torque transfer members supported by the rotor body. Each of the plurality of torque transfer members has a first end located between a respective pair of adjacent tubular cavities, and extends radially inward in a direction toward a rotational axis of the rotor.
