Manual vertical diffusion test system
“Start-up” 6-cell Manual Test System
A start-up vertical diffusion cell test system for manual use and sampling. This expanded package includes a 6-cell drive system with stainless stand, 6 vertical diffusion cells, convenient manual sampling syringe, jacketed media replace beaker, and supply kit. The circulating waterbath must be ordered separately. The start-up manual test system is adaptable for later addition of the new Vision Microette autosampler. See USP for further information.
In vitro diffusion testing of the transfer rate across membrane is a technology used for the study of skin transfer kinetics and to establish batch-to-batch uniformity of topical preparations. The procedure employs a diffusion cell that separates a donor compartment from a receptor compartment with a specified membrane.
