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: Free-standing AAO Wafers Nanoporous AAO Wafers or membranes are available in several standard sizes and thicknesses, and a wide selection of pore sizes. AAO Wafer Packs 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. AAO Wafers with Contacts AAO Wafers with contacts are designed for templated electrodeposition inside the pores of AAO. Why use AAO products from InRedox? - Extensive know-how and tightly controlled manufacturing - Superior self-organization and long-range pore ordering - Precise and reproducible pore geometries - Batch-to-batch consistency - Formats supporting the most popular applications - Broad range of specifications: - pore diameter from 5 nm to 300 nm - pore length from 0.1 µm to 200 µm - size from 3 mm to 250 mm (1/8″ to 10″) - Standard and custom shapes and sizes - Convenient tools and accessories.
Membrane holders are designed for supporting ceramic AAO membranes in separation, filtration and transport applications. These holders feature a streamlined seal design to maintain either upstream pressure or downstream vacuum and include a smooth porous metal frit to provide seamless support required for AAO membranes under cross-membrane pressure. Application Conditions: aqueous solutions with wide range of pH, inert gases (PEEK holder with Viton® O-rings); some aqueous solutions, organic solutions and vapors, gases (Stainless Steel 304 holder with Kalrez® or Graphite O-rings) Holder Materials: PEEK; Stainless Steel (304) O-ring Materials: Viton®; Kalrez® or Graphite Temperature range: 0 to 85 °C; -20 to 300 °C (with Kalrez® O-rings) up to 700°C (with Graphite seals) Pressure range: up to 150 psi / 1000 kPa; up to 450 psi / 3000 kPa Fittings Materials: Acetal or Delrin; Stainless Steel Common Specifications: - Filtration modes: dead-end (DE) filtration; tangential flow (TF) filtration – requires special fittings - Membrane Diameter: 25 mm (with optional inserts for 13 mm membranes); 33 mm; 47 (50) mm; 90 mm - Membrane thickness: 20 to 200 μm - Holder accommodates other types of membranes - Input / Output ports: 1/8″ NPTF thread (standard); could be modified by request (custom) Standard holder kit for 25 mm AAO Membranes includes: - Top (upstream) and bottom (downstream) flanges - Stainless steel support frit - Stainless steel hardware (3 screws, 3 nuts) - Set of 10 Viton® O-rings for selected membrane size(s) - Inserts for smaller membranes (optional, purchased separately) - Fittings (purchased separately) - Instruction manual Replacement parts available: - O-rings (Viton®, Kalrez®, Graphite) - Mounting hardware - Inserts for smaller membranes sizes (i.e, 13 mm in 25 mm holder) - Fittings for dead end filtration (1/8″ or 1/4″ OD tubing to 1/8″ NPT ports) - Fittings for tangential flow filtration (2 x 1/8″ or 2 x 1/4″ OD tubing to 1/8″ NPT ports)
