Abstract
A separation zone for separating platelets from a platelet-rich suspension establishes a relationship between its radial thickness (h) and axial height (Z) that, taking into account the given angular velocity of rotation and the given kinematic viscosity of the platelet-rich suspension introduced through the inlet, represents a (.lambda.) value that is less than 700, where ##EQU1## where: .OMEGA. is the angular velocity (in rad/sec);
