A bucket for use in a swinging bucket centrifuge rotor includes a cylindrical body having a pair of planar abutments formed thereon. The abutments are diametrically disposed on the body with respect to the axis thereof. A slot is formed between a portion of each abutment and the body of the bucket. Each abutment has a first groove that extends generally parallel to the axis of the body and a second groove that extends generally perpendicular to the axis of the body. The first and second grooves communicate with the slot and together with the slot cooperate to define a resilient spring element on each abutment. A bottom support surface on each abutment is generally cylindrical in shape and has an axis of generation that lies along the axis of the body, whereby a portion of each bottom support surface lies on opposite sides of the axis of the body.
