The challenge of producing high-quality emulsions, solutions, and dispersions can sometimes be a moving target due to changing market demands, consumer behavior, and product requirements. More than ever, pharmaceutical companies are reevaluating their mixing processes, looking for ways to lower cost, boost production capacity, improve product quality, or simplify cleaning and maintenance while still maintaining processing flexibility.
In particular, the use of high shear rotor/stator mixers has become more and more popular over the years. Compared to other agitation devices such as propellers, turbines, and saw-tooth dispersers, the versatile rotor/stator mixer offers better performance in terms of size reduction, homogenization and emulsification of a wide variety of formulations.
