Also known as centrifugal device, centrifuges

thumb|upright=1.15|A laboratory tabletop centrifuge. The rotating unit, called the rotor, has fixed holes drilled at an angle (to the vertical), visible inside the smooth silver rim. Sample tubes are placed in these slots and the motor is spun. As the centrifugal force is in the horizontal plane and the tubes are fixed at an angle, the particles have to travel only a short distance before they hit the wall of the tube and then slide down to the bottom. These angle rotors are very popular in the lab for routine use.
