Nylaflo Nylon Membrane Disc Filter - 0.45um, 90mm, 100/Pk SKU: 66609

Nylon Membrane Filters - 66609

The Pall 66609 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Manufactured to exacting specifications, a uniform Nylon matrix maintains its rated 0.45 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. As a result, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Broad compatibility with alcohols, aliphatic hydrocarbons, and aromatic solvents extends Nylon filtration into mixed-solvent sample preparation.
• High mechanical strength allows Nylon membranes to withstand elevated differential pressures without structural deformation.
• 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.
• Thermal stability of the membrane material allows safe operation at temperatures up to 55°C without degradation of retention characteristics or dimensional integrity.

Reproducible particle counting starts with a membrane surface that captures particles uniformly. The pore consistency documented above ensures your counts reflect the sample, not filter variation. To support this, mechanical strength that resists tearing during handling means less time managing fragile membranes and more time focused on your analytical results. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• 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.
• Solvent Mobilization - Clarifies organic mobile phases in glass vacuum holders, preventing particulate damage to sensitive HPLC pump seals.
• Alkaline Filtration - Withstands high-pH solutions during industrial fluid processing, offering durability where other polymers might degrade.
• Northern Blotting - Excellent for RNA transfer applications where high tensile strength is required for multiple rounds of probe stripping.
• Southern Blot Transfer - Binds nucleic acids strongly during capillary transfer, providing a durable matrix for repeated hybridization cycles.
