Nylon Membrane Filter Discs, 0.22um, 142mm, Hydrophilic, Nonsterile, 25/Pk
GVS SKU: 1213771

Featuring a naturally hydrophilic Nylon 66 membrane internally supported with an inert polyester web, these 142mm filter discs deliver dependable 0.22um filtration without the need for wetting agents that can interfere with biological processes. The polyester support web provides dimensional strength and stability that helps prevent cracking, tearing, curling, and breaking during handling. Supplied nonsterile in a convenient pack of 25.

Key Nylon Membrane Characteristics

• Naturally hydrophilic, so the membrane wets out evenly with water and aqueous solutions and requires no surfactants or wetting agents
• Internally supported with an inert polyester support web for added dimensional strength and stability
• Resists cracking, tearing, curling, and breaking, making it well suited to aggressive handling and automated equipment
• Low extractables help keep filtrate clean and pure for more consistent results
• Good resistance to many organic solvents, supporting broad use across aqueous and alcoholic solutions

Key Construction Characteristics

• Material: Nylon 66 membrane with integral polyester support layer
• Pore size: 0.22um nominal
• Diameter: 142mm flat disc format
• Sterility: Nonsterile
• Pack: 25 discs per pack

These discs maintain consistent flow and retention across the membrane surface, providing reliable particle removal for sample preparation. The hydrophilic, low-extractable structure helps preserve sample integrity while delivering uniform performance from disc to disc.
