CPT (Certified Phlebotomy Technician) Practice Exam

A centrifuge is a machine with a rapidly rotating container that applies centrifugal force to its contents. This force creates a separation of particles based on their mass, such as separating blood plasma from red blood cells. The options A, B, and D are incorrect because they are not actual words. Centrifugal refers to the outward force created by a spinning object, but it cannot be used to describe a machine. A centrifugalizer is not a real word at all. Centripetal refers to the inward force of a spinning object, which is the opposite of what a centrifuge does. Therefore, C is the only logical answer for the word that describes a spinning centrifuge.
