Material Specifications

• Alkaline-resistant and compatible with a broad range of aqueous buffers used in pharmaceutical and biotechnology laboratories.
• High mechanical strength allows Nylon membranes to withstand elevated differential pressures without structural deformation.
• Broad compatibility with alcohols, aliphatic hydrocarbons, and aromatic solvents extends Nylon filtration into mixed-solvent sample preparation.
• Ideal for filtering aqueous biological solutions and mobile phases.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

Air monitoring and stack emissions sampling demand a filter medium that withstands the thermal and chemical conditions at your collection point — the material properties described above define the operating envelope for your application. In these cases, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Wettability

Hydrophilic

• Southern Blot Transfer - Binds nucleic acids strongly during capillary transfer, providing a durable matrix for repeated hybridization cycles.
• Alkaline Filtration - Withstands high-pH solutions during industrial fluid processing, offering durability where other polymers might degrade.
• 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.
• 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.
