Abstract
A method for rapidly mixing a liquid solution in a container by causing a small magnetic mixing member to rapidly revolve within the solution in a generally circular pattern in response to a pair of revolving magnetic fields positioned alongside the container.
Claims25
A method for mixing a liquid contained in a container having a false bottom, the method comprising:
- placing a ferromagnetic mixing member within the liquid contained in the container;
- and,
- rotating a pair of magnetic fields in a circular pattern in close proximity to the container near the location of the false bottom,
- so that magnetic forces acting upon the mixing member cause it to revolve thereby generating a mixing motion within the liquid solution.

A method for mixing a liquid contained in a container, the method comprising:
- placing a ferromagnetic mixing member within the liquid contained in the container;
- rotating a pair of magnetic fields in a circular pattern in close proximity to the container;
- and,
- moving the container vertically relative to the magnetic fields so that magnetic forces acting upon the mixing member cause it to revolve thereby generating a mixing motion throughout the entirety of the liquid solution.

An apparatus for mixing a liquid within a liquid container having a false bottom, the apparatus comprising:
- a spherical ferromagnetic mixing member within the liquid in the container;
- a pair of magnetic field sources positioned at opposite sides of the container proximate the false bottom;
- and,
- means for rotating the magnetic fields in circular patterns in close proximity to the liquid container, so that magnetic forces acting upon the magnetic mixing member cause it to rotate, thereby generating a mixing motion within the liquid solution.
