Centrifuge

Digital centrifuge used in medical laboratory

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.
