Centrifuge

A centrifuge is a device with a motor in it, which is used to spin an object with high speed. This high speed spinning forces the object outwards. This force is used for several purposes:

 a uranium centrifuge is used to separate two isotopes of uranium (named U-235 and U-238) from each other;
 in medical laboratories, serum is separated from the blood samples using a centrifuge;
 in chemical laboratories, centrifuges are used to subtract solid parts of an emulsion from its liquid parts.
 large centrifuges are used by NASA to expose astronauts to high forces for their training.
