Ano Disc Circle w/out Support Ring, 13mm Diameter, 0.1um Pore Size (100/Pk) SKU: 6809-7013

Aluminum Oxide (Anopore) Membrane Filters - 6809-7013

Engineered for high retention efficiency and superior chemical stability, the Whatman 6809-7013 achieves reliable separation results across a broad range of analytical and preparative applications. Reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. With this in mind, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Precisely controlled pore geometry provides sharp molecular weight cutoffs for size-based separation of nanoparticles and macromolecules.
• Non-fibrous ceramic construction eliminates the shedding and fiber release associated with depth filter media.
• Thermally stable to over 400°C, Anopore membranes withstand sterilization and high-temperature processing without structural change.
• Inorganic and extremely rigid, offering no deformation under high pressure filtration.
• Anopore Aluminum Oxide membranes feature a unique honeycomb pore structure for precision.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. Here, near-zero extractable levels from the ceramic matrix mean your filtrate backgrounds approach the theoretical minimum, supporting the detection limits your trace-level analytical methods require without membrane-derived interference. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• Stack Pre-filtration - Acts as a spacer or depth layer in multi-tier filtration stacks to extend the life of the final downstream membrane.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
