PES Membrane Disc Filters, 0.1um, 90mm, Hydrophilic, Nonsterile, 25/Pk
GVS SKU: 1222230

Featuring a naturally hydrophilic polyethersulfone (PES) membrane, these 90mm disc filters deliver clean, reliable filtration at a 0.1um pore size without the need for added wetting agents. The strong, microporous asymmetric film is cast from a high-temperature polyethersulfone polymer that resists acids and bases, supplied nonsterile in packs of 25.

Key PES Membrane Characteristics

• Naturally hydrophilic: Wets out without added surfactants, eliminating wetting agents that can interfere with analyses.
• Low drug and protein binding: Maximizes recovery of critical drugs and proteins during filtration.
• Low extractables: Helps ensure test results are not compromised by leached materials.
• Acid and base resistant: The high-temperature polyethersulfone polymer withstands aggressive handling and automated equipment.
• Asymmetric microporous structure: Provides uniform, controlled porosity for efficient particulate removal and dependable flow.

Key Construction Characteristics

• Membrane material: Polyethersulfone (PES), naturally hydrophilic.
• Pore size: 0.1um.
• Diameter: 90mm.
• Sterility: Nonsterile.
• Pack: 25 per pack.

The strength and durability of this membrane make it well suited to demanding workflows that involve aggressive handling or automated equipment. Its uniform porosity and low-binding surface help protect sample integrity, supporting consistent recovery and reproducible results across a range of aqueous life science applications.
