Nylon Membrane Circle, 0.2um Pore Size, 47mm, 100/Pk SKU: 7402-004

Nylon Membrane Filters - 7402-004

Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention across the full operating range. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

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

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. Under these conditions, nylon's compatibility with both aqueous and moderate organic solvent systems lets you standardize on one membrane type across HPLC sample prep workflows that alternate between reversed-phase and normal-phase mobile phases. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Wettability

Hydrophilic

• Alkaline Filtration - Withstands high-pH solutions during industrial fluid processing, offering durability where other polymers might degrade.
• 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.
• Southern Blot Transfer - Binds nucleic acids strongly during capillary transfer, providing a durable matrix for repeated hybridization cycles.
• Radiolabeled Assays - Retains radiolabeled DNA/RNA fragments efficiently, ensuring accurate quantification in molecular biology experiments.
