PES Membrane Disc Filters, 0.8um, 47mm, Nonsterile, 100/Pk
GVS SKU: 1214568

Featuring a naturally hydrophilic polyethersulfone (PES) membrane cast from a high-temperature polymer, these 47mm membrane discs deliver dependable particulate removal during general filtration. With a 0.8um pore size and a measured thickness of 0.11 to 0.15mm, the asymmetric microporous structure wets out spontaneously in water and aqueous solutions without added wetting agents, supporting clean, reproducible results across life science workflows.

Key PES Membrane Characteristics

• Naturally hydrophilic: wets out without added surfactants, eliminating wetting agents that could interfere with downstream analyses.
• Low protein and drug binding: maximizes recovery of critical drugs and proteins from the filtrate.
• Low extractables: contributes minimal leachable material so test results are not compromised.
• Asymmetric microporous structure: high-temperature PES polymer resistant to acids and bases for broad chemical tolerance.
• Strength and durability: withstands aggressive handling and automated equipment while maintaining membrane integrity.

Key Construction Characteristics

• Membrane material: Polyethersulfone (PES), plain (ungridded) surface.
• Format: 47mm diameter disc with a 0.8um pore size.
• Thickness: 0.11 to 0.15mm.
• Sterility: supplied nonsterile.
• Packaging: 100 discs per pack.

These discs provide consistent flow and uniform particulate retention for repeatable filtration. Their low-binding, low-extractable PES medium helps preserve sample integrity, protecting sensitive analytes during preparation and clarification. Lot-to-lot uniformity supports dependable performance across routine laboratory use.
