Development of a micromixing system for treatment of ORL 48 microtissues in different concentrations of cytochalasin B

Mixing and dilution are essential procedures in pharmaceutical operation to process two or more components in a separate or thoroughly mixed condition until homogenous solution was obtained. However, conventional serial dilution method used in laboratory assessment causes high usage of reagents, hig...
