PURPOSE:To enhance the magnetic field intensity, pass a culture solution through a region with a high magnetic flux density and more effectively carry out magnetizing treatment by arranging specific magnetic members in the central hole part of annular magnets. CONSTITUTION:The first magnetic members 20 are attached to one surface of annular magnets 10 and 10 provided in the course of a culture solution inflow pipe and the second magnetic members 30 are then attached to the other surface tc locate columnar protrusions 31 of the magnetic members 30 in the central parts of the central holes of the annular magnets. A culture solution is passed through culture solution flow spaces 40 and culture solution flow holes 32 and efficiently subjected to magnetizing treatment. |
