What is the function of a centrifuge in laboratory work?

Explanation:
A centrifuge works by using rapid spinning to separate a mixture based on density. In blood, the heavier cells settle to the bottom while the lighter plasma or serum stays above, creating distinct layers that can be analyzed or used for tests. Heating samples and measuring pH are done with other equipment, and rotor balancing is a safety step rather than the purpose of centrifugation. So the centrifuge’s function is to separate the contents of blood by spinning.
