PES Syringe Filters, 1.2um, 47mm, Nonsterile, 100/Pk
GVS SKU: 1221008

Featuring a naturally hydrophilic polyethersulfone (PES) membrane cast from pure polyethersulfone polymer, these 47mm filter discs deliver dependable particulate removal during general filtration. The 1.2um pore size suits clarification and prefiltration of aqueous and compatible non-aqueous solutions, while the membrane wets out without added wetting agents that could interfere with downstream analyses. Each pack contains 100 nonsterile discs.

Key PES Membrane Characteristics

• Naturally hydrophilic: wets out spontaneously without surfactants or wetting agents that can compromise results.
• Low extractables: minimizes leachable contamination so test results are not skewed by membrane background.
• Low protein and drug binding: maximizes recovery of critical proteins and drugs from the sample.
• Asymmetric microporous structure: a strong, high-temperature PES film that is acid and base resistant for broad chemical tolerance.
• Durable construction: strength and dimensional stability support aggressive handling and automated equipment.

Key Construction Characteristics

• Membrane material: hydrophilic polyethersulfone (PES).
• Pore size: 1.2um nominal.
• Diameter: 47mm disc format.
• Sterility: nonsterile.
• Pack: 100 discs per pack.

The uniform, controlled pore structure provides reliable particulate removal and consistent flow across the disc. Low binding and low extractables help preserve sample integrity, while the acid and base resistant PES film maintains performance across a broad range of aqueous and compatible solvent solutions.
