Diffusion testing is a release rate test of an active pharmaceutical ingredient in semisolid form as it permeates through a skin-like membrane into solution. Diffusion replicates the process of skin-applied medicine as it permeates the skin into the body for local or systemic action. It is ideal for the quality control of topical preparations.
The Hanson 6-Cell Manual Diffusion Test System is a startup vertical diffusion cell test system ideal for manual use and sampling and is adaptable for later addition of the Vision Microette autosampler. The Vision Microette diffusion test system automates sampling from groups of six Hanson Vertical Diffusion Cells (VDCs) for extensive unattended tests and handles surfactants, saline, and hydroalcoholic receptor solutions.
Hanson Research worked with EMD Millipore to develop a special dosage wafer for the Hanson VDC that accommodates the Strat-M® membrane from EMD Millipore.Vision® Microette™ Automated Test System
