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 is 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.

The invention relates to a sample container, comprising a housing which forms a sample space for receiving a sample and has at least one circular opening which extends in a channel-shaped manner into the sample space, and further comprising a spherical closing element, wherein the diameter of the closing element only exceeds the diameter of the opening channel in at least one (closing) portion to such an extent that the closing element can be fixed in a force-locked manner by its largest circumference in the closing portion, wherein the spherical closing element is in contact with the housing, and the opening channel between the closing portion and the inner opening forms a protrusion which reduces the opening cross section of the opening channel with respect to the opening cross section in the closing portion.
