Flow-through Dissolution USP 4

The flow-through dissolution method offers complete flexibility on media volumes and allows repeatable positioning of virtually all dosage forms such as powders, APIs, lipophilic forms, suppositories, suspensions, liposomes, microspheres, semi-solids, implants, and medical devices including drug eluting stents. Described in United States Pharmacopeia (USP) as Apparatus 4, FDA guidelines, European Pharmacopoeia (Ph.Eur.), and other harmonized Pharmacopeia, dissolution testing using a flow-through cell is proven to characterize the active drug release in terms of bioequivalence and in-vitro / in-vivo correlation (IVIV) in clinical studies and daily QC routines alike.

Sometimes referred to as the "Swiss Army Knife", flow-through cells allow dissolution testing of virtually all dosage forms. SOTAX was the first manufacturer to develop a standardized flow-through dissolution tester and has ever since helped Pharmaceutical companies all over the world in designing robust flow-through methods - and new flow-through cells for novel dosage forms.

The global standard.

The SOTAX CE 7smart flow-through dissolution tester allows you to see differences in your formulations that paddle and basket methods simply won't show. Widely recommended for poorly soluble, modified / extended release, and low dose products, the CE 7smart is also frequently used for in-vitro / in-vivo correlation (IVIVC) studies and a growing range of dosage types.
