Rotor

A centrifuge comprising a trough (2), a rotor (3) intended to be disposed in the trough (2), and means (4) for driving the rotor (3) in rotation about a central axis of rotation (A), wherein a number n of seats (81, 82, 101 and 102) for receiving a product to be centrifuged are provided in the rotor, the seats being arranged eccentrically relative to the axis of rotation, the seats (81, 82, 101, 102) being of a substantially analogous shape, elongate in a respective longitudinal direction (D), wherein the geometric image (I) of at least a first seat (81), through a geometric rotation about the axis of rotation (A) in a first direction of rotation (S1) and an angle of 360°/n, is different from a second seat (101) which directly follows the first seat (81) in the first direction of rotation (S1), wherein the second seat (101) is substantially the image, through a geometric transformation, of the geometric image (I) of the first seat (81) said geometric transformation comprising a geometric rotation by a non-zero angle (α) in a plane orthogonal to the axis of rotation (A) and/or 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.
