In a 4 Point centrifuge the vibration are isolated with a help of heavy Inertia Plate and Visco Dampers instead of a 3 point pendulum suspension where the vibration of centrifuge are isolated with a help of Spring and Pendulum Bolts arrangement.

The centrifuges mounted on 4 Point are slowly replacing the 3 Pendulum machines because of the following inherent benefits.

Level of vibrations is much lower.

Special Foundation not required, hence foundation cost reduced

Can be installed on upper floor hence mobility is much more simpler.

No maintenance required for Visco dampers hence it avoids maintenance in suspension system.
