PES Membrane Filter Discs, 0.45um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1214475

Featuring a strong, microporous asymmetric polyethersulfone (PES) film cast from pure, high-temperature polymer, this 47mm membrane disc delivers reliable particulate removal during general filtration. With a 0.45um pore size and a plain surface, the membrane is naturally hydrophilic and wets out evenly without added wetting agents. The film measures 0.11 to 0.15mm thick and is supplied nonsterile in packs of 100. Its acid and base resistance, combined with low protein and drug binding, makes it well suited to life science sample preparation.

Key PES Membrane Characteristics

• Naturally hydrophilic: wets out spontaneously with aqueous solutions and eliminates the need for wetting agents that can interfere with analyses.
• Low protein and drug binding: maximizes recovery of critical proteins and drugs from filtered samples.
• Low extractables: minimizes the risk of compromising test results with leached contaminants.
• Acid and base resistant: the high-temperature PES polymer withstands aggressive handling and a broad range of chemistries.
• Asymmetric microporous structure: provides uniform porosity and dependable, fast flow rates with high throughput.

Key Construction Characteristics

• Membrane material: polyethersulfone (PES), plain surface, white.
• Format: 47mm membrane disc, 0.45um pore size.
• Thickness: 0.11 to 0.15mm.
• Sterility: nonsterile.
• Pack: 100 discs per pack.

The uniform pore structure and controlled porosity provide consistent, repeatable filtration across lots, protecting the integrity of each sample. With its naturally hydrophilic nature and low binding profile, the membrane supports accurate downstream analysis while maintaining sample integrity throughout preparation.
