Diffusion Cells

PermeGear vertical glass diffusion cells are the original Franz Cells. Standard orifice diameters are 5mm, 7mm, 9mm, 11.28mm, 15mm, 20mm and 25mm, other diameters are custom. The word “orifice” as it refers to a Franz Cell is the area at the top of the receptor chamber that is exposed to the membrane or device through which transport or permeation is being studied. Corresponding volumes from 5ml to 20ml are standard and are listed under Typical Dimensions.

PermeGear In-Line Cells may be thought of as a flow type Franz Cell with a very small receptor volume. In-Line Cells locate the membrane of interest in the horizontal plane and have donor chambers open to the air although occluded donor chambers are available.
