We have designed non-contact mixers for mixing various solutions for medical and biotechnological applications. A new type of superconducting mixer is composed of three parts: top permanent magnet, bulk superconductor, and bottom permanent magnet. Here the bulk superconductor is inserted into a liquid nitrogen bath and is free to rotate. The top magnet component is immersed in a solution with the rotating wing on top. The component has a multi-pole configuration and is coupled with the bulk superconductor by flux pinning. The bottom magnet component is laid outside the system, and also has a multi-pole configuration and is coupled with the bulk superconductor by flux pinning. When the bottom component was rotated with the outer rotation device, the top magnet component rotated without contact by virtue of flux pinning, which shows that one can make non-contact mixers.
