It has been known that convection due to density differences within liquids is suppressed in the microgravity environment inside the International Space Station, and that this leads to the production of high-quality protein crystals1). Therefore, experiments in a levitated state are expected to have applications in medicine and biology. However, conducting experiments in space requires a huge amount of money, and there are various restrictions in terms of human resources, time, and experimental equipment. On the other hand, technology to reproduce microgravity-like environments on Earth is also being researched, and one such technology is diamagnetic levitation, but it is not very versatile because it requires large superconducting magnets or hybrid magnets. Recently, we discovered that diamagnetic levitation of water and other diamagnetic materials can be achieved by simply combining small permanent magnets2), and we have also succeeded in recrystallizing water-soluble salts from supersaturated aqueous solutions that have been levitated. In general, the magnetic force fields required for magnetic levitation of aqueous solutions are different from that of crystals, therefore, it is difficult to find a magnet arrangement that satisfies both at the same time. Therefore, in this study, we introduce a new device that can be used to perform recrystallization experiments from aqueous solutions that have been levitated by in-situ controll of the magnetic force.
