Which device uses centrifugal force to separate particles from a suspension?

• A. Beaker
• B. Centrifuge
• C. Bottle
• D. Florence Flask

Answer: (B)

Applying centrifugal force to a suspension lets components separate by density and size. When a sample spins in a centrifuge, the rapid rotation creates outward radial force that pushes heavier, denser particles toward the bottom of the container, forming a dense pellet, while lighter components remain in the supernatant. This separation is the basis for many lab tasks, like isolating cells from blood or purifying macromolecules. The other options are simply containers used to hold liquids or mixtures, not devices that generate the forces needed to separate components. The centrifuge is specifically designed to provide the high-speed rotation and resulting centrifugal acceleration needed for this kind of separation.
