PTFE hydrophilic Syringe Filters, 0.45um, 13mm, Nonsterile 100/Pk SKU: SF18099

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18099

Pharmaceutical quality control laboratories, biotechnology research facilities, and analytical testing organizations require precise clarification solutions for small-volume samples where particulate removal is critical but sterile filtration is not necessary. Advanced laboratory capabilities demand membrane technology that delivers consistent 0.45μm particle retention while maintaining chemical compatibility across diverse analytical solvents and sample matrices. Engineered with compact 13mm architecture and hydrophilic PTFE membrane chemistry, this filtration system provides validated clarification performance through 21.75psi bubble point integrity testing. Design optimization includes 10μL minimal holdup volume for precious sample conservation, polypropylene housing construction rated to 60°C operation, and integrated prefilter protection extending membrane operational life while processing 10ml sample volumes efficiently.

Key PTFE Membrane Characteristics

• Validated 0.45μm Clarification Performance - Removes interfering particles while allowing passage of dissolved components for accurate analytical measurements
• Hydrophilic Surface Treatment - Modified fluoropolymer surface eliminates pre-wetting requirements, enabling direct aqueous sample processing
• Broad Solvent Compatibility - Resists aggressive chemicals and organic solvents while maintaining documented incompatibilities for safe operation
• Low Protein Binding Properties - Maintains concentration of biological molecules and prevents interference in protein-based assays
• 21.75psi Bubble Point Validation - Ensures consistent pore structure and filtration performance across production lots

Key Construction Characteristics

• 10μL Minimal Holdup Volume - Minimizes loss of valuable analytical samples through optimized dead space design for maximum recovery
• Compact 13mm Design Configuration - 1.09cm² filtration area provides efficient processing for small volume applications up to 10ml capacity
• Dual Luer Connection System - Universal Luer-Lok/Luer Slip interface ensures compatibility with standard laboratory syringe equipment
• Polypropylene Prefilter Protection - Extends primary membrane life while maintaining 11ml flow rate for rapid sample processing

Built for your demanding analytical clarification requirements, this hydrophilic PTFE system delivers structural integrity through 87psi operational ratings while maintaining efficient flow characteristics. Your laboratory operations benefit from immediate sample compatibility and minimal sample loss, while the robust prefilter design ensures reliable performance across diverse sample types and extended analytical campaigns in challenging laboratory environments.
