Machines applying centrifugal force to their contents to separate fluids or solids of differing densities. Available in both electronic or hand-powered models of varying capacities, and with a variety of rotors, accessories, and replacement parts.

Centrifuges and microcentrifuges are commonplace in laboratories. They are used to separate solutions using the centrifugal force created by the rotor moving on a fixed axis. Successful sample centrifugation depends on the density, temperature, and viscosity of the sample and solution, and the speed of the rotation.
