Abstract
A magnetically-coupled stirring apparatus is provided. The stirring apparatus includes a rotor including at least one rotor magnet, with the rotor being positioned within a chamber. The stirring apparatus further includes an offset stirrer device positioned outside of the chamber. The offset stirrer device includes a shaft including a first end and a second end, with a stirring device axis being offset from a rotor axis, one or more paddle portions extending from the second end, and at least one stirrer magnet affixed to the first end. The at least one rotor magnet magnetically interacts with the at least one stirrer magnet. Rotation of the rotor induces rotation of the offset stirrer device.
