Nylon Membrane Filter Discs, 0.45um, 13mm, Nonsterile, 100/Pk
GVS SKU: 1213774

Featuring a naturally hydrophilic nylon (PA6.6) membrane internally supported with an inert polyester web, this 0.45um, 13mm filter disc wets out evenly with water and aqueous solutions while resisting cracking, tearing, curling, and breaking during handling. The polyester support web provides dimensional strength and stability that makes the membrane well suited to aggressive handling and automated equipment, and because nylon is inherently hydrophilic it requires no wetting agents that could interfere with biological processes.

Key Nylon Membrane Characteristics

• Naturally hydrophilic: wets out evenly with water and aqueous solutions and eliminates the need for wetting agents that can interfere with biological processes.
• Polyester-supported structure: an inert internal polyester support web adds dimensional strength and stability, preventing cracking, tearing, curling, and breaking.
• Durable for automation: the added strength and durability is advantageous during usage involving aggressive handling or automated equipment.
• Low extractables: contributes minimal extractable material for clean, consistent results.
• Broad compatibility: inert nylon 66 is suitable for filtration of aqueous and organic solvent solutions.

Key Construction Characteristics

• Membrane material: nylon (PA6.6) with integral polyester support web.
• Pore size: 0.45 um nominal.
• Diameter: 13 mm plain white disc.
• Sterility: nonsterile.
• Pack: 100 discs per pack.

This membrane delivers uniform, repeatable filtration performance across the disc, supporting consistent flow and reliable particulate retention. Its low extractables and naturally hydrophilic surface help preserve sample integrity for clarification, chromatography sample preparation, and general laboratory filtration.
