Nanoporous Anodic Aluminum Oxide Wafers are free-standing isotropic AAO membranes without the barrier layer at the bottom of the pores.  This form factor, with pores open on both faces of AAO, is the most common choice for many applications.  Click on one of the images below to purchase these products:

nanoporous anodic alumina membranes and wafers

Nanoporous AAO Wafers or membranes are available in several standard sizes and thicknesses, and a wide selection of pore sizes.

Free-standing AAO wafers, OD 100 mm x H 150 µm

AAO Volume Packs and AAO Variety Packs are a cost-effective option for customers who require multiple wafers or membranes with same or different pore diameters.

nanoporous AAO wafers with metal contact for templated electrodeposition

AAO Wafers with contacts are designed for templated electrodeposition inside the pores of AAO.
