Nylon Membrane Filter Discs, 0.22um, 13mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1213766

Featuring a naturally hydrophilic Nylon 66 (PA6.6) membrane, these 13mm, 0.22um filter discs wet out evenly in aqueous samples without the wetting agents that can interfere with biological processes. The membrane is internally supported by an inert polyester web that delivers dimensional strength and stability, allowing it to retain integrity during demanding manual or automated handling. Supplied as plain white, nonsterile discs in packs of 100, this membrane provides consistent flow and diffusion for general filtration and analytical sample preparation.

Key Nylon Membrane Characteristics

• Naturally hydrophilic: wets out evenly and eliminates the need for wetting agents that can interfere with biological processes.
• Polyester-supported structure: an inert internal polyester web adds dimensional strength and stability, preventing cracking, tearing, curling, and breaking.
• High porosity: 70/80% porosity supports high diffusion and low flow resistance.
• Low extractables: contributes minimal extractable material for clean, consistent analytical results.
• Durable and autoclavable: withstands aggressive handling and automated equipment, and tolerates steam sterilization.

Key Construction Characteristics

• Membrane material: Nylon 66 (PA6.6), supported by an inert polyester web.
• Format: 13mm plain white membrane disc.
• Pore size: 0.22um.
• Sterility: nonsterile, supplied 100 discs per pack.

This membrane delivers reliable, repeatable filtration with consistent flow and diffusion rates across lots. Its low extractables and naturally hydrophilic surface help preserve sample integrity for downstream analysis. The polyester-reinforced construction maintains membrane integrity even under aggressive handling, supporting dependable performance in both manual and automated workflows.
