PES Membrane Disc Filters, 0.1um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1214756

Featuring a naturally hydrophilic polyethersulfone (PES) membrane cast from pure polyethersulfone polymer, these 47mm discs deliver a 0.1um pore size for fine particulate retention in general and life science filtration. The asymmetric, microporous structure wets out without added wetting agents, supporting reproducible recovery across aqueous samples. Supplied nonsterile in a pack of 100, each disc carries a plain (ungridded) surface and a membrane thickness of 0.11 to 0.15mm.

Key PES Membrane Characteristics

• Naturally hydrophilic: wets out evenly without added wetting agents that can interfere with downstream analyses.
• Low protein and drug binding: maximizes recovery of critical proteins and drugs from filtered samples.
• Low extractables: minimizes the introduction of contaminants that could compromise test results.
• Acid and base resistant: the high-temperature polyethersulfone polymer withstands aggressive handling and chemically demanding solutions.
• Asymmetric microporous structure: provides strength and durability suited to manual use or automated equipment.

Key Construction Characteristics

• Membrane material: hydrophilic polyethersulfone (PES).
• Format: 47mm plain disc, 0.1um pore size.
• Membrane thickness: 0.11 to 0.15mm.
• Sterility: nonsterile.
• Pack: 100 discs per pack.

These discs maintain consistent retention and flow for dependable particulate removal across repeated runs. The low-binding, low-extractable PES medium helps preserve sample integrity, protecting both recovery and analytical accuracy. Lot-to-lot consistency supports reproducible filtration in routine laboratory workflows.
