Abstract: An orbital shaker device (1) for biotechnological and/or biomedical applications comprises a frame (10), a platform (15) for receiving biotechnological and/or biomedical containers (50), eccentric couplings (13, 14) for allowing an orbital movement of the platform (15) relative to the frame (10), counterweight units (17, 18) for balancing the orbital movement, and at least one motor (19) for driving the eccentric couplings (13, 14). The device comprises two eccentric couplings (13, 14) arranged near respective opposite edges (27, 28) of the platform (15), while each counterweight unit (17, 18) is arranged approximately in the plane of the combined center of gravity of the platform (15) and the containers (50). Furthermore, both eccentric couplings (13, 14) are driven by the motor (19) or motors, either directly or indirectly. In this way, an optimal vibration compensation is achieved while allowing an imaging unit (40) to be mounted underneath the platform (15).
