Used in research, quality control and product development laboratories, the Enhancer Cell provides release rate data for topicals using your standard Apparatus 1 or 2 with either a standard 1L paddle method or 200 mL vessel with mini paddle. Also known as the Vertical Diffusion Cell and External Receptor Chamber Type, the Enhancer Cell is a PTFE cell with adjustable volume and retaining cap to eliminate air pockets trapped against the skin or artificial membrane that provide the diffusion barrier. It is a cost-effective alternative to investing in the fragile and more labor-intensive Franz Cells.
