Free-standing nanoporous AAO wafers with pores open on both faces (also known as anodic alumina membranes or nanotemplates) are the most popular form factor for many applications.

Wide selection of wafer sizes, pore diameters and AAO thicknesses in stock for on-line ordering and quick delivery.

No minimal order – just select AAO parameters and in the pull-down menu below and add to cart.

Customization – if  you need different specifications, review the table below and contact us with your requirements.

For those who need more than a few wafers for their project, AAO Wafer Packs offer significant cost savings per unit:

AAO Volume Packs

Packs of 20, 50 or 100 wafers or membranes of the same size, thickness and pore diameter.

AAO Variety Packs

Assortment of AAO wafers with different pore diameters, 3 to 10 wafer per pore size.
