Regenerated Cellulose Membrane Filters, 0.45um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 3099755

Featuring a hydrophilic, high-strength regenerated cellulose membrane, these 47mm disc filters deliver a 0.45um pore size for dependable particle removal and sample clarification. The regenerated cellulose media provides broad solvent compatibility and contributes very low extractable material across a wide variety of sample solvents, making it well suited to standalone filtration and sample preparation. Supplied nonsterile in packs of 100, these discs offer consistent flow and clean filtrate for routine laboratory and analytical work.

Key Regenerated Cellulose Membrane Characteristics

• Naturally hydrophilic: wets out evenly for reliable, consistent filtration without added wetting agents.
• High mechanical strength: the regenerated cellulose media maintains its integrity during handling and use.
• Broad solvent compatibility: withstands a wide range of aqueous and organic solvents.
• Very low extractables: contributes minimal extractable material across diverse sample solvents, protecting downstream analyses.
• Sterilizable media: can be sterilized by all common methods while maintaining mechanical stability.

Key Construction Characteristics

• Pore size: 0.45um for sample clarification and particulate removal.
• Diameter: 47mm disc format for standard filtration holders and funnels.
• Sterility: supplied nonsterile.
• Pack: 100 discs per pack.

These regenerated cellulose disc filters provide reliable, repeatable particle removal while protecting sample integrity through low extractable levels. Their broad chemical compatibility supports both aqueous and solvent-based workflows, delivering clean, consistent filtrate for analytical and preparative applications.
