    Abstract: A bucket is capable of holding a sample container in a rotary centrifuge. The bucket has a receptacle to receive the sample container and a trunnion joined to the bucket. The trunnion has a plurality of cutouts that each define a flexible span that is sufficiently thin to flex under application of a centrifugal force generated by the rotary centrifuge, and pivot pins to that allows the bucket to pivot under the application of the centrifugal force. The receptacle has an open end having an internal surface with a tapering groove and a self-seating cap having pegs sized to fit in the tapering groove.
