Nylon Membrane Filter Discs, 0.22um, 90mm, Hydrophilic, White, Nonsterile, 25/Pk
GVS SKU: 1213770

Featuring a naturally hydrophilic Nylon 66 (PA6.6) membrane internally supported by an inert polyester web, this 0.22um, 90mm disc wets out evenly without wetting agents and maintains its strength during demanding filtration work. The supported structure resists cracking, tearing, curling, and breaking, providing the dimensional stability needed for general filtration, clarification, and medical assays. Each disc is plain white, non-gridded, and supplied nonsterile in a pack of 25.

Key Nylon Membrane Characteristics

• Naturally hydrophilic: wets out evenly without surfactants or wetting agents that can interfere with biological processes.
• Low extractables: delivers clean, pure filtrate for consistent, reproducible results.
• Broad chemical compatibility: suited to aqueous solutions and many organic solvents, though not recommended for strong acids or bases.
• Polyester-supported structure: an inert internal support web adds strength and dimensional stability for aggressive handling and automated equipment.
• High porosity: a 70/80% porous structure supports high diffusion and low flow resistance.

Key Construction Characteristics

• Pore size: 0.22um for fine particulate retention and clarification.
• Diameter: 90mm disc format.
• Appearance: plain white, non-gridded membrane.
• Thermal tolerance: heatable and autoclavable, unaffected by temperatures up to 180C (356F) and steam sterilization.
• Packaging: nonsterile, 25 discs per pack.

This membrane delivers reliable, repeatable retention while preserving sample integrity through its low-extractable, naturally hydrophilic construction. Its supported design holds up to repeated handling and automated workflows, maintaining membrane integrity across runs. The result is dependable performance for HPLC sample preparation, clarification, and general laboratory filtration of aqueous and organic solvent solutions.

• Sample Clarification Removes fine particulates from aqueous and organic solvent solutions to produce clear, analysis-ready filtrate.
• HPLC Sample Preparation Prepares samples for chromatography by retaining sub-micron particulates that could compromise instrument performance.
• Microbiology Supports general microbiological filtration where a fine 0.22um hydrophilic membrane is required.
• Organic Solvent Filtration Filters alcohols and many organic solvents thanks to nylon's broad chemical compatibility.
• Aqueous Solution Filtration Filters aqueous solutions without wetting agents due to the membrane's natural hydrophilicity.
• Medical and Clinical Assays Provides a strong, dimensionally stable membrane suited to medical assay workflows and automated handling.
