US Patent 11958026 Low volume magnetic mixing system

A mixing system for use in a process bottle for mixing its contents, the mixing system including a low volume magnetically-driven mixer mounted at the bottom of the bottle. The mixer may have vanes and lower grooves, or no vanes and grooves on both upper and lower faces. The mixer has a “microsized” three-dimensional solid inanimate body to enable insertion through relatively small mouth openings at the top of conventional reactor bottles. Methods of assembly are also disclosed which involve passing the microsized mixer through an open mouth of a process bottle and coupling the mixer with a bearing assembly at the floor of the bottle. The bearing assembly includes fixtures sealed around a hole in the floor of the bottle.
