Polyethersulfone PES Syringe Filters, 0.45um, 17mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18254

Polyethersulfone (PES) Syringe Filters - SF18254

Featuring hydrophilic polyethersulfone membrane technology optimized for rapid clarification of small volume samples in sterile environments. A 0.45µm pore configuration, combined with glass fiber prefiltration, delivers exceptional flow rates while removing particulates from sensitive biological and pharmaceutical preparations. Tisch Scientific engineers precision 17mm diameter construction with minimal holdup volume, maximizing sample recovery in microscale and analytical applications.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane provides instant wetting without surfactants or pre-conditioning
• Superior chemical resistance withstands aggressive organic solvents and pH ranges from 1-14
• Low protein binding characteristics preserve analyte concentration and biological activity
• 0.45µm pore size delivers reliable clarification and suspended particulate removal
• Sterile packaging ensures contamination-free filtration for sensitive applications

Key Construction Characteristics

• Glass fiber prefilter captures larger particles, extending primary membrane service life
• Dual Luer-Lok/Luer Slip connections accommodate all standard syringe configurations
• Compact 17mm diameter design optimizes performance for small volume filtration
• 20µl holdup volume ensures maximum sample recovery in precious or limited samples

SF18254 syringe filters achieve remarkable 26.5ml/min flow rates through a compact 1.65cm² filtration area, accelerating your sample processing while maintaining consistent 31.91psi bubble point integrity. Glass fiber prefiltration technology protects the primary membrane from fouling, delivering reliable performance throughout the 20ml throughput capacity for your critical small-volume applications. Individually packaged sterile units eliminate contamination risks, ensuring reproducible results when processing your most sensitive samples requiring both clarification and sterility assurance.
