Abstract: A device for the reversible immobilization of biomolecules includes a container which can be filled with a liquid containing biomolecules and has an opening and a valve. The valve can be opened and closed by a closing mechanism for the controllable drainage of the liquid. Magnetic particles, to which the biomolecules can be immobilized can be arranged freely movable in the container. A magnet for fixing the magnetic particles in the container is arranged at the container, and the liquid can be removed from the container through the opening in the open state of the valve.

Abstract: A device for the reversible immobilization of biomolecules by magnetic particles includes a container. The container is configured to be filled with a liquid containing biomolecules and a magnet. The magnet is arranged on the container in such a way that magnetic particles arranged in the container and to which the biomolecules are capable of being immobilized, are configured to be fixed in the container. An inhomogeneous magnetic field id configured to act on the magnetic particles disposed in the container and is capable of being generated by the arrangement of the magnet, so that the magnetic particles are arranged in a structured manner by the influence of the inhomogeneous magnetic field.
