Patent ID: 7857744

Claim:
A cell separation chamber configured to be mounted on a rotor, said rotor having an axis of rotation, said cell separation chamber having an axis of symmetry and comprising an inlet for biologic fluids on said axis mountable radially outwardly from said axis of rotation, said inlet having a coupling for an inlet line, and an outlet on said axis of symmetry mountable radially inwardly from said inlet towards said axis of rotation, said outlet comprising a cap having a frustro-conical section tapering towards said axis and a coupling for an outlet line at an apex of said frustro-conical section, an entry section extending radially inwardly from said inlet, said entry section having a wall comprising an outwardly flared curve forming a first surface of rotation about said axis, said entry section having an axial length along said axis of said cell separation chamber and an inmost maximum diameter perpendicular to said axial length, and at least one section spaced radially inwardly from said entry section, said at least one section having a wall comprising an inward curve forming a surface of rotation about said axis.
