GLA-5000 PVC Membrane Disc Filters - 5um, 47mm, 100/Pk SKU: 66468

Nylon Membrane Filters - 66468

The Pall 66468 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. In addition, precision-manufactured Hydrophobic membrane with a verified 5.0 pore structure delivers consistent retention across the full operating range. In sum, lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Materials of construction maintain their mechanical and chemical properties at temperatures up to 52°C, supporting heated filtration protocols.
• Alkaline-resistant and compatible with a broad range of aqueous buffers used in pharmaceutical and biotechnology laboratories.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• High mechanical strength allows Nylon membranes to withstand elevated differential pressures without structural deformation.
• Flexible and durable, eliminating the need for wetting agents that could contaminate samples.

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. With these demands in mind, mechanical strength that resists tearing during handling means less time managing fragile membranes and more time focused on your analytical results. 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.

Wettability

Hydrophobic

• Solvent Mobilization - Clarifies organic mobile phases in glass vacuum holders, preventing particulate damage to sensitive HPLC pump seals.
• Radiolabeled Assays - Retains radiolabeled DNA/RNA fragments efficiently, ensuring accurate quantification in molecular biology experiments.
• 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.
• 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.
