Patent ID: 6986731

Claim:
A rotor ( 3 ) intended to be driven in rotation about a central axis of rotation (A), comprising: a number n of seats ( 8 1 , 8 2 , 10 1 and 10 2 ) for receiving a product to be centrifuged, the seats being arranged eccentrically relative to the axis of rotation, the seats ( 8 1 , 8 2 , 10 1 , 10 2 ) being of a substantially analogous shape, elongate in a respective longitudinal direction (D), wherein the geometric image (I) of at least a first seat ( 8 1 ), through a geometric rotation about the axis of rotation (A) in a first direction of rotation (S 1 ) and through an angle of 360°/n, is different from a second seat ( 10 1 ) which directly follows the first seat ( 8 1 ) in the first direction of rotation (S 1 ), and wherein the second seat is substantially the image, through a geometric transformation, of the geometric image (I) of the first seat ( 8 1 ), said geometric transformation comprising at least one of i) a geometric rotation by a non-zero angle (α) in a plane orthogonal to the axis of rotation (A) and ii) a geometric translation by a non-zero distance (d) in a plane orthogonal to the axis of rotation (A), the direction of the translation being inclined with respect to the longitudinal direction (D) of the geometric image (I) of the first seat.
