Title: Centrifuge rotor having swinging members with variable pivot points

Abstract: A centrifuge rotor has a plurality of swinging buckets or bucket carriers disposed on its periphery. Mounting pins, having an oblong cross-section, for the buckets are secured to the rotor itself. These pins are pivotally engaged with enlarged holes in the buckets such that the oblong pivots encounter a shifting pivot point as the buckets swing outwardly during spinning. This facilitates the bucket's hanging with an inward slant when at rest and yet assuming a true horizontal position when it spins.
