What is a centrifuge used for?

Explanation:
Spinning a sample at high speed uses centrifugal force to separate components by density. Heavier particles settle toward the bottom of the tube, forming a pellet, while the lighter liquid remains above as the supernatant. This density-driven separation is what centrifuges are designed to do, helping to isolate cells, sediments, or specific components from a mixture. Blending would mix everything together, not separate it. Measuring volume is done with calibrated glassware, and heating requires a heat source, not a centrifuge.
