Sterile Hydrophobic PVDF Syringe Filter, 0.22 µm, 25mm, Glass Prefilter, 100/Pk SKU: LE-IWT-ES10226

Featuring dual-layer hydrophobic PVDF membrane technology delivering exceptional chemical resistance and ultra-low protein binding for demanding analytical applications. PVDF syringe filter has the lowest protein adsorption in the syringe filter, while the integrated glass microfiber prefilter dramatically increases loading capacity and extends service life. The glass fiber prefilter reduces particle loading and extends service life, usually providing greater total throughput when processing samples with high particulate content.

Key PVDF Membrane Characteristics

• Hydrophobic PVDF construction provides superior chemical compatibility with organic solvents, alcohols, and mild acids
• Ultra-low protein binding properties maximize recovery of valuable biomolecules and high-value proteins
• Excellent weather resistance, anti-aging performance and chemical stability with high fluid transport performance
• 0.22 µm pore size delivers absolute retention for sterilization and clarification applications
• Gamma-sterilized individual blister packaging ensures sterility and prevents contamination

Key Construction Characteristics

• Concentric funnel-shaped polypropylene housing increases filtration volume while decreasing back pressure
• Glass microfiber prefilter layer captures large particulates before reaching the primary membrane
• Female Luer-Lock inlet and male Luer slip outlet provide secure, leak-free connections
• Ultrasonically bonded construction ensures reliability and prevents bypass flow
• Clear membrane type identification molded directly into housing for easy verification

PVDF syringe filters are specialized filtration devices used in laboratories for various applications requiring high chemical resistance, low protein binding, and compatibility with aggressive solvents. Low extractables and UV transparency make these filters crucial for HPLC and UV-sensitive protocols, particularly useful for protein and peptide solutions, Western and Northern blot buffers, enzyme media sterilization. The dual-layer design combines high-capacity prefiltration with final sterilization-grade membrane performance, maximizing throughput while maintaining sample integrity for critical chromatographic and analytical applications.
