ABSTRACT:
A rotor for a centrifugal separator. The rotor has a rotor body with a cylindrical outer wall extending upward from a bottom portion and a boss portion provided at a center of the bottom portion. The outer wall is located radially outward with respect to the boss portion serving as a rotational center of the rotor body. The rotor also has a plurality of buckets that are swingably supported in the rotor body and each of the buckets holds a boxlike sample container. A supporting element supports a hinge shaft serving as a swing center of the bucket. Each of the buckets has a bottom surface that is brought into contact with an inside surface of an outer wall of the rotor body due to a centrifugal force when the rotor rotates, so that the buckets and the rotor body integrally rotate during centrifugal operation. The hinge shaft is offset from a line extending from a centroid of the bucket perpendicularly to the bottom surface of the bucket, and is located at a position higher than the sample container and the bucket inclines obliquely with respect to the bottom portion of the rotor body when the rotor body is stopped.
