      Featuring sterile hydrophobic PVDF membrane technology with integrated glass fiber prefilter delivering exceptional protein recovery and extended service life for demanding biological applications. The 0.45µm pore configuration provides reliable clarification of viscous solutions while the glass fiber prefilter reduces particle loading experienced by the membrane final filter and extends service life, achieving greater total throughput when compared to filters without prefilter. Individually blister-packed construction maintains sterility while Luer-Lok® connections ensure leak-tight syringe attachment for consistent results. Key PVDF Membrane Characteristics • Lowest protein adsorption among syringe filter materials maximizes recovery of valuable proteins and peptides in biological samples • Hydrophobic surface chemistry delivers superior compatibility with organic solvents, alcohols, and mild acids for versatile sample processing • Exceptional chemical resilience with non-reactive properties to many solvents, acids and bases expands application flexibility • 0.45µm pore size achieves optimal balance between particulate retention and flow rate for HPLC sample preparation • Sterile gamma-irradiated construction eliminates microbial contamination risks in critical analytical protocols Key Construction Characteristics • Integrated glass fiber prefilter protects membrane from clogging and increases total throughput for particle-laden solutions • Concentric funnel-shaped barrel design increases sample volume capacity while decreasing back pressure during filtration • Medical-grade polypropylene housing withstands higher operating pressures with broad chemical compatibility • Ultrasonically bonded assembly ensures reliable seal integrity throughout filtration process • Individual blister packaging maintains sterility and prevents contamination until point of use LE-IWT-ES10227 filters achieve enhanced throughput by retaining particles greater than 2.0 micron at the prefilter stage, optimizing your sample preparation efficiency for complex biological matrices. Outstanding unit-to-unit reproducibility delivers consistent results across your analytical workflows, while the prefilter layer acts as a coarse screen reducing direct contact of particulates with the final membrane. Sterile individually-packaged design transforms these filters into validated reference-grade media for protein solutions, oligomers, and water-soluble polymers requiring both high recovery and contamination-free processing in your most critical HPLC and chromatographic applications.
