The document describes a lab-scale mixer called the Lab-O-Mix that is suitable for existing glass beakers. It can achieve pilot plant-like results under correct parameters with a variable frequency drive that allows speeds from 0-1800 RPM and a multiple impeller system. The Lab-O-Mix is also able to overcome mass transfer limitations through baffling in standard beakers and can handle a vast range of corrosive fluids as it has a PFA coating.
