Swinging-bucket centrifuge rotors feature a full pathlength, slow run time, and excellent resolution.

The swinging bucket rotor allows the tube to change angle during the run. The buckets are vertical when stopped and horizontal when running. The parallel geometry of the swinging buckets allow the sample to move through the density gradients without interruption, unlike fixed-angle geometry, where the sample hits the wall and smears, which can compromise the separation.

Ideal for separating large volume samples at low speeds and are particularly useful when samples are to be resolved in rate-zonal (density) gradients. Applications include tissue culture processing, high throughput protocols such as harvesting whole cells from growth, processing of blood collection tubes and rate-zonal separations (i.e., based on size or mass) media.
