Centrifuge - Wikipedia
A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong. The centrifuge works using the sedimentation principle , where the centrifugal acceleration causes denser substances and particles to move outward ... Read Article
