Membrane Discs - Box of 47mm 0.45 um Nylon Membranes, 100/Pk SKU: NX047100

Nylon Membrane Filters - NX047100

The Pall NX047100 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Supporting this capability, verified 0.45 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Working in concert, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Broad compatibility with alcohols, aliphatic hydrocarbons, and aromatic solvents extends Nylon filtration into mixed-solvent sample preparation.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Ideal for filtering aqueous biological solutions and mobile phases.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 55°C, supporting heated filtration protocols.
• Alkaline-resistant and compatible with a broad range of aqueous buffers used in pharmaceutical and biotechnology laboratories.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. In these cases, inherent hydrophilic character eliminates the pre-wetting step required by other membrane types, letting you begin aqueous filtration immediately and reduce hands-on preparation time. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Atmospheric Testing - Used in dry deposition sampling to capture specific atmospheric nitrates and sulfates for environmental quality studies.
• Solid Phase Extraction - Acts as a frit or barrier in custom extraction columns, retaining sorbent beds while allowing solvent to pass through.
• Gene Mapping Support - Provides a stable, charge-modified surface for DNA immobilization, facilitating precise gene mapping and analysis steps.
• Southern Blot Transfer - Binds nucleic acids strongly during capillary transfer, providing a durable matrix for repeated hybridization cycles.
• Northern Blotting - Excellent for RNA transfer applications where high tensile strength is required for multiple rounds of probe stripping.
• Radiolabeled Assays - Retains radiolabeled DNA/RNA fragments efficiently, ensuring accurate quantification in molecular biology experiments.
