Related to centrifugation: Differential centrifugation


1. An apparatus consisting essentially of a compartment spun about a central axis to separate contained materials of different specific gravities, or to separate colloidal particles suspended in a liquid.
2. An apparatus in which humans or animals are enclosed and which is revolved to simulate the effects of acceleration in a spacecraft.
