Sentino ME25 Membrane, 0.45um, Dispenser Packs of 200, 1000/Pk SKU: 68121ME

Nylon Membrane Filters - 68121ME

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Alkaline-resistant and compatible with a broad range of aqueous buffers used in pharmaceutical and biotechnology laboratories.
• Naturally hydrophilic and constructed with high tensile strength, Nylon provides reliable performance without pre-wetting in aqueous applications.
• Broad compatibility with alcohols, aliphatic hydrocarbons, and aromatic solvents extends Nylon filtration into mixed-solvent sample preparation.
• Thermal stability of the membrane material allows safe operation at temperatures up to 55°C without degradation of retention characteristics or dimensional integrity.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.

Air monitoring and stack emissions sampling demand a filter medium that withstands the conditions at your collection point. The material properties above define that operating envelope. Addressing this directly, dual compatibility with aqueous and organic solvent systems reduces your consumable inventory. A single membrane chemistry handles buffer filtration, mobile phase preparation, and sample clarification without switching between filter types. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophilic

• Northern Blotting - Excellent for RNA transfer applications where high tensile strength is required for multiple rounds of probe stripping.
• Gene Mapping Support - Provides a stable, charge-modified surface for DNA immobilization, facilitating precise gene mapping and analysis steps.
• Solid Phase Extraction - Acts as a frit or barrier in custom extraction columns, retaining sorbent beds while allowing solvent to pass through.
• 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.
• Atmospheric Testing - Used in dry deposition sampling to capture specific atmospheric nitrates and sulfates for environmental quality studies.
