Universal rotor for all systems used to subject fluids to centrifugal accelerations

A method of using a universal rotor, in an apparatus, the method comprising:

• circulating one or more liquids submitted to stable and adjustable centrifugal accelerations, at high pressures and at temperatures able to be varied with short time constants,
• said apparatus being a chemical and/or biochemical reactors and/or for extractions, separations and purification in centrifugal partition chromatography (CPC), the fluids comprising organic or non-ionic liquids, ionic liquids, CO2 in liquid or supercritical phase,
• using said rotor of said apparatus, which includes one or more discs stacked one on top of the other, each of said discs including a retainer in which a ring is inserted into an assembly of one or more circular sectors,
• providing a space between ends of a single circular section for a single circular sector or arranging said space between said ends of said contiguous circular sectors for several circular sectors, and
• inserting a linking connector into said space or spaces, and directly contacting outlets of a linking connector with inlets of another linking connector of a next of said discs, said linking connectors having branching channels to cause a liquid phase entering through inlets to be guided to travel through a network of cells to outlets.
