Cellulose Acetate Membrane Filters, 0.22um, 47mm, Nonsterile, 100/Pk
GVS SKU: 1213804

Featuring a pure cellulose acetate membrane internally supported by an inert polyester web, this 47mm filtration disc delivers naturally low protein binding for applications where maximal sample recovery is critical. The 0.22um hydrophilic membrane maintains uniform porosity for consistent flow and dependable retention, while the polyester support reinforces the media against cracking, tearing, and distortion during handling.

Key Cellulose Acetate Membrane Characteristics

• Naturally hydrophilic media wets out readily with aqueous solutions for fast, reliable filtration.
• Low protein binding minimizes sample loss and adsorption, making it ideal for proteinaceous and biological solutions.
• Supported structure built on an inert polyester web gives each disc exceptional strength to resist cracking, tearing, and distortion.
• Dimensional stability withstands autoclaving and steam sterilization at temperatures up to 135C (274F).
• High throughput with reduced filter changes when processing proteinaceous solutions.

Key Construction Characteristics

• Pore size: 0.22um for fine clarification and microbiological work.
• Diameter: 47mm circular disc format.
• Color: white, not gridded.
• Sterility: nonsterile.
• Pack: 100 membranes per pack.

This membrane provides reliable, repeatable filtration performance while preserving sample integrity. Its low-binding cellulose acetate chemistry protects recovered proteins and enzymes, and the reinforced construction ensures each disc remains intact through handling and sterilization.
