Abstract
A fixed angle centrifuge rotor is provided including a rotor body having an upper surface and a plurality of tubular cavities extending from the upper surface to respective bottom walls. A pressure plate is operatively coupled to the bottom walls of the tubular cavities and is configured to transfer torque to the bottom walls. The pressure plate is configured to be directly coupled to a rotor hub and to receive torque directly from the rotor hub.
Claims31
A fixed angle centrifuge rotor, comprising:
- a rotor body having an upper surface and a plurality of tubular cavities extending from the upper surface to respective bottom walls, each cavity being configured to receive a sample container therein;
- a pressure plate operatively coupled to the bottom walls and configured to transfer torque to the bottom walls,
- wherein the pressure plate is configured to be directly coupled to a rotor hub and to receive torque directly from the rotor hub via a plurality of bores defined by a lower surface of the pressure plate;
- and
- at least one pin disposed within a bore of the plurality of bores for directly coupling the pressure plate to the rotor hub.
