The maximum centrifugal acceleration developed inside a centrifuge is a func-tion of its radius and angular rota-tional speed. More commonly, the term G-Force (G-Value) is used instead of acceleration. The G-Force is defined as the multiple of the gravitational con-stant that is obtained in the centrifuge. The centrifugal acceleration (G-Force)
Using the force of gravity. In essence, a disc stack separator is a settling tank whose base is wrapped around the center line of the bowl. Rapid rotation of separator bowl means that the effect of gravity is replaced by a controllable centrifugal force, or gravitational force known as G-force, that can have an effect up to 10,000 times greater than the force of gravity.
