2124816 9408692 PCTABS00032 A method for separating platelets from a platelet-rich suspension comprising rotating a separation zone about an axis (14) at a given angular velocity (.OMEGA.), the separation zone including a low-G side (16) located closer to the rotational axis (14) than the other, high-G (18) to create between them a chamber (10) having a radial thickness (h) and an axial height (Z) measured with respect to the axis (14) of rotation, and an inlet (20) for introducing a platelet-rich suspension and the separation zone establishing a relationship between the radial thickness (h) and the axial height (Z) of the chamber (10) that taking into account the given angular velocity of rotation (.OMEGA.) and the given kinematic viscosity (v) of the platelet-rich suspension introduced through the inlet (20), represents a value (.lambda.) that is less than 700, where .lambda. = (2h3)/(Z).
