Abstract:
This disclosure relates to a magnetic mixing apparatus that mixes a sample contained in a mixing chamber using a stir bar, while minimizing the amount of contact between the stir bar and walls of the mixing chamber. In one aspect, the apparatus comprises a ferromagnetic stir bar contained in the mixing chamber, and a driving magnet and a driven magnet located on opposite sides of the mixing chamber. The driving magnet, the driven magnet, and the ferromagnetic stir bar are each capable of rotating about a respective axis. The driving magnet, the driven magnet, and the ferromagnetic stir bar are magnetically coupled such that rotation of the driving magnet induces rotation of the driven magnet and rotation of the driving magnet and the driven magnet induce rotation of the ferromagnetic stir bar. In some embodiments, rotation of the ferromagnetic stir bar within the mixing chamber mixes the sample contained within the mixing chamber.

Claim (Index 1):
A magnetic mixing apparatus comprising:\n a driving magnet system configured to rotate about a driving magnet rotational axis, the driving magnet system comprising one or more driving magnets; a drive motor, wherein the driving magnet system is operably coupled to the drive motor, and the drive motor is capable of driving rotation of the driving magnet system about the driving magnet rotational axis; a driven magnet system configured to rotate about a driven magnet rotational axis, the driven magnet system comprising one or more driven magnets; a gap separating the driving magnet system and the driven magnet system, wherein the arrangement of the driven and driving magnet systems effectuates a magnetic coupling between each driving magnet and a corresponding driven magnet whereby rotation of the driving magnet system about the driving magnet rotational axis induces rotation of the driven magnet system about the driven magnet rotational axis; a stationary mixing assembly disposed within the gap, wherein the mixing assembly comprises a mixing chamber having a mixing chamber volume and comprising a bounding surface surrounding the mixing chamber volume, such that the entire bounding surface surrounding the mixing chamber volume is disposed within the gap; and a stir bar contained within the mixing chamber volume, the stir bar comprising a stir bar volume and a ferromagnetic material, wherein disposition of the stir bar between the driving magnet system and the driven magnet system creates a low-reluctance magnetic circuit and effectuates a magnetic coupling between the stir bar, at least one of the one or more driving magnets, and at least one of the one or more driven magnets, whereby rotation of the driving magnet system about the driving magnet rotational axis and rotation of the driven magnet system about the driven magnet rotational axis induces rotation of the stir bar about a stir bar rotational axis.
