Nylaflo Nylon Membrane Disc Filter - 0.2um, 47mm, 100/Pk SKU: 66602

Nylon Membrane Filters - 66602

The Pall 66602 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Consequently, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Naturally hydrophilic and constructed with high tensile strength, Nylon provides reliable performance without pre-wetting in aqueous applications.
• Ideal for filtering aqueous biological solutions and mobile phases.
• Broad compatibility with alcohols, aliphatic hydrocarbons, and aromatic solvents extends Nylon filtration into mixed-solvent sample preparation.
• Alkaline-resistant and compatible with a broad range of aqueous buffers used in pharmaceutical and biotechnology laboratories.
• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.

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. In response, alkaline resistance that other membranes cannot match means you can filter high-pH buffers, basic mobile phases, and caustic wash solutions without the membrane degradation that limits cellulose-based and PES alternatives. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Radiolabeled Assays - Retains radiolabeled DNA/RNA fragments efficiently, ensuring accurate quantification in molecular biology experiments.
• Solid Phase Extraction - Acts as a frit or barrier in custom extraction columns, retaining sorbent beds while allowing solvent to pass through.
• Atmospheric Testing - Used in dry deposition sampling to capture specific atmospheric nitrates and sulfates for environmental quality studies.
• Southern Blot Transfer - Binds nucleic acids strongly during capillary transfer, providing a durable matrix for repeated hybridization cycles.
• Gene Mapping Support - Provides a stable, charge-modified surface for DNA immobilization, facilitating precise gene mapping and analysis steps.
• Solvent Mobilization - Clarifies organic mobile phases in glass vacuum holders, preventing particulate damage to sensitive HPLC pump seals.
