A gripper unit for handling a vessel for receiving biological material is proposed, inter alia. The vessel has a lid which can assume an open position and a closed position. The gripper unit comprises a gripper for gripping and releasing the vessel, and a lid holder, for holding a lid in a defined position in relation to the vessel. The defined position is an open position of the lid.

Apparatus for processing biological material

A centrifuge with a rotor set-up having at least one magnetic bearing is invented to operate a novel centrifuge. The rotor arrangement is connected with at least one permanent magnet configuration which is radially separated by small gap from a passive superconducting magnet stator. The permanent magnets which are adjusted in such a way that the escaping magnetic flux penetrates the adjacent surface of the passive superconducting magnet stator at a substantially perpendicular orientation. A driving motor unit, preferably in the form of a contactless induction engine, ensures a free and frictionless rotation. The passive superconducting magnet stator is comprised a melt textured superconducting YBCO material of high critical current density which can be cooled below its critical temperature of T&equals;92 K using an integrated cryogenic unit to obtain the superconducting state. The stator has a preferred shape of a cylinder or hollow cylinder.

Locking devices for locking two components that move relative to one another such as a housing and a cover are disclosed. The locking devices have two catches disposed on one component and opposite to one another and symmetrically with respect to a stop disposed on the second component and arranged in a plane of symmetry between the opposing catches. The catches have hook ends facing the plane of symmetry and the two catches are connected to a common shaft at the ends of the catches facing away from the hook ends. The common shaft is disposed in the plane of symmetry and is movable within the plane of symmetry toward and away from the stop. The shaft is arranged on a spindle disposed in the plane of symmetry or parallel to the plane of symmetry and engaged with a motor-driven gear to effect movement of the shaft. The catches have longitudinally-extending guide elements whose longitudinal axis does not run parallel to the plane of symmetry. The guide elements engage stationary guide pins disposed parallel and symmetrically with respect to the plane of symmetry. This arrangement provides the guidance of the catches when the shaft is moved toward and away from the stop. When the shaft is at rest in a position nearest to the stop, the hook ends of the catches are opposed across the plane of symmetry. When the shaft is moved downwardly away from the stop, the hook ends of the catches move into the plane of symmetry, without lateral forces, to close around the stop from two opposing sides. This ensures equal stress on the closed lock from all sides, even under high stress and, particularly, high lateral stresses placed upon the locked-together components.
