How does a swing out centrifuge work?

Explanation:
In a swing-out centrifuge, the tube holders are hinged so they can swing outward as the rotor spins. When the rotor is at rest, the tubes hang vertical. As speed increases, centrifugal force pushes the hinged buckets outward until the tubes are oriented roughly horizontal. This changes the tube axis to be perpendicular to the rotation axis, which improves separation by sedimentation and keeps the layers well separated, while reducing splash and mixing. This swinging action and horizontal final orientation are the defining features that distinguish swing-out rotors from fixed-angle designs.
