PES Syringe Filters, 0.22 um, 33mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF14508

Polyethersulfone (PES) Syringe Filters - SF14508

Featuring pre-sterilized high-capacity polyethersulfone membrane technology with sterilizing-grade 0.22µm pore size for immediate bacterial filtration of large sample volumes. Ready-to-use sterile 33mm format delivers exceptional throughput up to 110ml while maintaining complete bacteria removal essential for bioprocessing and pharmaceutical applications. Tisch Scientific combines hydrophilic PES membranes with integrated glass fiber prefiltration to maximize flow rates without compromising sterile filtration performance in demanding production and quality control workflows.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane enabling instant filtration without pre-wetting steps
• Sterilizing-grade 0.22µm pore size, ensuring complete bacterial retention
• Minimal protein binding, preserving biological activity and sample integrity
• Membrane thickness of 100-160µm, providing consistent filtration performance
• Superior chemical compatibility with aqueous solutions and mild organics

Key Construction Characteristics

• High-capacity 33mm diameter format supporting large-volume sterile filtration
• Integrated glass fiber prefilter protecting the membrane from particulate fouling
• Holdup volume of 100µL ensuring efficient recovery despite larger format
• Universal Luer-Lok/Luer Slip connectivity accommodating all syringe types

SF14508 syringe filters maintain optimal flow rates of 50ml through a 4.6cm² active filtration area, maximizing your throughput efficiency for high-volume sterile filtration applications. A bubble point of 43.51psi validates membrane integrity for critical processes requiring documented performance in regulated environments. Pre-sterilized individual packaging eliminates preparation time while ensuring immediate use in aseptic applications, maintaining operational capability up to 60°C for your most demanding sterile filtration requirements.
