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.
