Analysts interested in vertical diffusion cell (VDC) testing systems can now use Teledyne Hanson’s online configurator tool to build and review systems suited to specific applications. The Phoenix line of precision diffusion testing instruments provides efficient controls with a user-friendly interface, and high resolution release-rate testing results. The online tool makes it easy to explore more than 78 different configurations based on manual versus automated sampling; three different vertical diffusion cell sizes with two different mixer-inserts resulting in six different receptor media volumes; a collection of modular, interchangeable, precision-machined cell cap kits allowing various combinations of donor chamber volume and membrane exposed area (orifice diameter) to accommodate a wide range of topical and transdermal drug formulations; and several wetted materials choices including chemically inert PTFE. Create configurations, save them online, and reload, review, and revise them again later. Submit your preferred configurations online to receive free quotations and sales consultations. For further information on the Phoenix DB-6 manual sampling system or the Phoenix RDS automated testing platform, see Phoenix Dry Heat Systems.
