Abstract
A timing and control mechanism for a centrifuge comprising a piston to which is attached a cam having cam surfaces which interact with flexible tubing to control the rate of flow through the tubing. The velocity of the piston in the centrifugal force field is determined by the resistance to flow of fluid which the piston displaces. The movement of the cam is therefore a measure of the speed and duration of the centrifugal force.
