US 2004/0165477 A1 · Radial continuous coupled magnetic mixing device

Abstract

A mixing apparatus comprises a plurality of reactors/reaction vessels controlled by a single graphical user interface. Each of the reactor modules is independent and may be used as such. A magnetic impeller is located inside each reaction vessel, the impeller having a magnet integrated into the profile. External magnets are located radially outside of the wall of each reaction vessel. Rotational motion is provided to these external magnets thereby inducing the internal magnetic impellers to rotate and induce mixing/agitation to the reaction vessel contents. The usage of strong external magnets enables strong magnetic coupling to the internal impeller enabling mixing of normally difficult to mix contents. The ability to adjust the vertical location of the external magnets further enhances functional ability enabling optimized location of the internal magnet for the specific volume/vessel content mixtures combinations.

Dependent claims

A laboratory mixing device comprising:

a. at least one reactor;
b. a wheel encompassing the at least one reactor such that the axis of the wheel is substantially coaxial with the at least one reactor;
c. at least one drive magnet positioned upon the wheel and rotatable, the at least one drive magnet comprising at least one permanent magnet and providing opposite magnetic poles upon the wheel;
and
d. at least one mixer comprising a permanent magnet positioned within the at least one reactor, wherein a magnetic coupling between the at least one drive magnet and the mixer results in rotation of the mixer when the at least one drive magnet rotates.
