What is the advantage of a swing out head centrifuge?

• A. More solid pellet and less disturbance
• B. Higher speeds
• C. Requires less maintenance
• D. Slower rpm

Answer: (A)

The advantage comes from how a swing-out rotor moves the tubes to a horizontal position during spinning. That orientation makes the sediment pile straight down to the bottom of the tube, forming a tighter, more compact pellet. A denser pellet is easier to see and remove the supernatant from without disturbing the pellet, giving cleaner separation and less risk of resuspending material. Higher speeds, less maintenance, or slower rpm aren’t inherent benefits of this design, whereas the improved pellet quality and reduced disturbance are the direct advantages.
