Dissolution Testing USP 4

The flow-through dissolution method (USP 4 / EP Flow-through cell) offers complete flexibility on media volumes and allows repeatable positioning of virtually all dosage forms: powders, suspensions, suppositories, APIs, lipophilic forms, liposomes, microspheres, semi-solids, implants, as well as medical devices including drug eluting stents. Dissolution and drug release testing using a flow-through cell is proven to characterize the active drug release in terms of bioequivalence and in-vitro / in-vivo correlation (IVIVC) in clinical studies, as well as daily QC routines alike. With 30 years of experience, SOTAX was the first manufacturer to develop a standardized flow-through dissolution unit.
