  • Publication number: 20210222154
    Abstract: The present invention relates to a method for operating magnetic particles in a device in which gel-like medium layer and liquid layer are alternately arranged inside the hollow tube and, first liquid layer and second liquid layer are separated by gel-like medium layer, and magnetic solid with large particle size exists in the first liquid layer rather than magnetic particles and the said magnetic particles. The method of the present invention comprises the first step of moving the magnetic particles and the magnetic solid in the first liquid layer to the gel-like medium layer, the second step of moving the magnetic particles and the magnetic solid moved into the gel-like medium layer into the second liquid layer, and the third step of inverting the movement of the magnetic particles and the magnetic solid moved into the second liquid layer into the gel-like medium layer, by operating a magnetic field.

  • Publication number: 20190381515
    Abstract: A magnet is disposed close to and outside a container held by a container holding part, and relatively moves along the container, so as to move the magnetic particles in the container by a magnetic force. A housing accommodates the magnet and the container holding part in the housing in a state where a position of the magnet relatively moving along the container is not visually recognizable from the outside. A display unit is provided on the housing so as to be visually recognizable from the outside and has light emitting regions that can emit light. A processing step execution unit sequentially executes a plurality of processing steps by relatively moving the magnet. When the plurality of processing steps are sequentially executed, a light emission control unit causes the light emitting regions to emit light according to a position of the magnet.
