  • Patent number: 5496255
    Abstract: A swinging bucket centrifuge rotor having a conforming bucket seat which includes a plurality of cavities evenly spaced about its vertical axis. Each has a seat portion that with an inward profile generally following the profile of a swinging bucket, subjected to centrifugal forces. A passageway extends entirely through the rotor head and includes a slot extending radially outward from the passageway, positioned so as to bifurcate the seat portion. Located between the vertical axis and the passageway is an improved hanging mechanism that reduces the likelihood of improperly mounting a swinging bucket onto the rotor. Three embodiments of the hanging mechanism are disclosed, each of which is integrally formed with the inner wall of each cavity. The hanging mechanism is positioned so that during centrifugation, the seat portion of the rotor will bear the full centrifugal force of the bucket.
