Abstract
A magnetic mixing device designed to mix fluid in a reaction chamber and remove air bubbles if present. The device comprises a holder with embedded magnets, which causes movement of a stir bar within the reaction chamber. The holder may be moved by an electric linear actuator configured to generate linear motion or an electric motor configured to generate a circular motion. When orientated so the stir bar moves vertically within the reaction chamber, the stir bar disrupts any air bubbles trapped within or below the fluid.
Claims16
A method of mixing in a reaction chamber, comprising:
- applying a force to rotate a holder containing a magnet, wherein the holder is positioned adjacent to the reaction chamber and the holder rotates about a rotation axis perpendicular to a longitudinal axis of the reaction chamber, the rotation axis extending below a bottom of the reaction chamber;
- and
- causing vertical movement of a magnetic stir bar within the reaction chamber by magnetic coupling between the magnet and the magnetic stir bar;
- wherein the vertical movement of the stir bar creates a uniformly mixed solution and disrupts air bubbles in the reaction chamber.
