PVDF Sterile Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 13mm, 100/Pk SKU: LE-IWT-ES10224

Featuring dual-layer PVDF membrane technology with integrated glass fiber prefilter delivering exceptional particle loading capacity and extended service life for demanding protein and biological sample filtration. Hydrophobic PVDF construction provides exceptionally low protein binding and broad chemical compatibility, while the glass fiber prefilter reduces particle loading experienced by the membrane final filter and extends service life for applications with fluids containing high levels of suspended solids. Individual blister packaging ensures sterile integrity with Luer-Lock® connectivity for secure, leak-tight syringe attachment during critical filtration protocols.

Key PVDF Membrane Characteristics

• Ultra-low protein binding characteristics maximize recovery of valuable proteins and biomolecules during sterilization
• Hydrophobic membrane surface chemistry provides exceptional compatibility with organic solvents and mixed aqueous solutions
• Broad chemical and pH compatibility with high chemical resilience being non-reactive to many solvents, acids and bases
• 0.22µm pore rating delivers absolute sterile filtration while maintaining optimal flow characteristics
• Gamma irradiation sterilization with controlled exposure ensures sufficient dose for sterility validation

Key Glass Fiber Prefilter Construction

• Glass fiber prefilter optimized for particle-laden liquids protects membrane from early clogging and increases total throughput
• Prefilter layer acts as coarse screen reducing direct particulate contact with final membrane, increasing filtration capacity per filter
• Excellent compatibility with organic solvents and strong acids (except hydrofluoric acid) and bases for versatile sample processing
• 13mm diameter format accommodates sample volumes up to 12mL with optimized flow dynamics
• Rugged polypropylene housing construction withstands operating pressures while maintaining dimensional stability

These sterile syringe filters achieve superior performance in sterilization of enzyme/protein solutions, nutrient media for cell/tissue cultures, and biological fluids while delivering exceptional clarification for protein immunoassay samples, western blotting buffers, and nucleic acid hybridization applications. Individual sterile packaging eliminates cross-contamination risks during storage and handling, while Luer-Lock® connectivity ensures reliable syringe attachment even under elevated filtration pressures. Enhanced particle loading capacity from the integrated glass fiber prefilter maximizes your sample throughput, reducing filter changeouts and accelerating your laboratory workflow efficiency.
