Polytetrafluoroethylene (PTFE) Syringe Filters - SF18075

Critical sterile filtration and mycoplasma removal applications face challenges due to membrane fouling, protein loss, and pre-wetting complications, which compromise sample integrity and laboratory productivity. Conventional filtration approaches struggle with achieving absolute retention while maintaining flow rates necessary for high-volume processing. Advanced hydrophilic PTFE membrane technology at 0.1μm pore size eliminates these obstacles through surface-modified fluoropolymer chemistry that provides immediate aqueous compatibility and absolute mycoplasma retention. Technical specifications include 29psi bubble point validation ensuring complete 0.1μm particle retention, 33mm high-capacity design with 4.9cm² filtration area, and 100μL dead volume optimization supporting 110ml throughput capacity for demanding laboratory workflows.

Key PTFE Membrane Characteristics

• Absolute 0.1μm Retention - Provides complete mycoplasma removal and critical sterile filtration with 29psi bubble point validation
• Hydrophilic Surface Modification - Eliminates pre-wetting protocols through proprietary treatment, enabling immediate sample processing
• Selective Chemical Resistance - Maintains compatibility with aggressive analytical solvents while providing clear incompatibility documentation
• Protein Preservation Technology - Low-binding characteristics maintain the concentration of sensitive biomolecules and therapeutic proteins
• Validated Membrane Thickness - 80-140μm engineered depth ensures structural integrity while maintaining consistent filtration performance

Key Construction Characteristics

• 100μL Optimized Dead Volume - Preserves samples through a minimal holdup design, maximizing recovery of precious analytical specimens
• 33mm High-Capacity Platform - 4.9cm² effective filtration area enables efficient processing of large sample volumes up to 110ml
• Universal Luer Interface System - Dual Luer-Lok/Luer Slip connections accommodate all standard laboratory syringe configurations
• Integrated Polypropylene Prefilter - Extends membrane life through particulate protection while maintaining 12ml flow rate efficiency

Engineered for your most demanding sterile filtration requirements, this hydrophilic PTFE system combines operational confidence through 87psi pressure ratings with validated mycoplasma retention capabilities. Your laboratory achieves maximum productivity through high-volume processing capacity and immediate sample compatibility, while the robust construction ensures consistent performance across extended filtration campaigns and challenging biological matrices.
