Uses of Centrifuge - Introduction, History, Appliion

The human centrifuge was first discovered in the year 1933. This kind of centrifuge is designed to evaluate and help train the pilots and the astronauts to fly in extreme high conditions. Another vital appliion of centrifuges is stimulating the gravitational force applied to humans. This type of appliion is suitable for space.

Laboratory Centrifuges | Biocompare

2022-4-8 · Laboratory Centrifuges. A centrifuge is a laboratory device that is used for the separation of fluids, gas or liquid, based on density. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel. This apparatus is found in most laboratories from

centrifuge | Definition & Facts | Britannica

centrifuge, any device that applies a sustained centrifugal force—that is, a force due to rotation. Effectively, the centrifuge substitutes a similar, stronger, force for that of gravity. Every centrifuge contains a spinning vessel; there are many configurations, depending on use. A perforated rotating drum in a laundry that throws off excess water from clothes, for example, is a type of
