1. In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it floats to the top.
2. The greater the difference in density, the faster they move. If there is no difference in density (isopycnic conditions), the particles stay steady.
3. To take advantage of even tiny differences in density to separate various particles in a solution, gravity can be replaced with the much more powerful "centrifugal force" provided by a centrifuge.
4. A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a potentially strong force perpendicular to the axis of spin (outward).
