Thumbnail Filmstrip of Tri-Layer PTFE Hydrophobic Syringe Filter, GF/PP Prefilter, 0.45µm, 25mm, Nonsterile, 100/Pk Images
Featuring advanced tri-layer PTFE membrane technology delivering exceptional chemical resistance and high-particulate sample processing capabilities for demanding analytical applications. Ultra-low binding PTFE construction provides maximum chemical compatibility with pH values 1-14 while hydrophobic surface characteristics optimize organic solvent filtration and gas venting protocols. Glass microfiber and polypropylene prefilter layers significantly extend service life by reducing particle loading on the primary membrane, delivering superior total throughput for high-solids samples.
Key PTFE Membrane Characteristics
- Chemically inert hydrophobic PTFE membrane withstands harsh solvents across full pH range of 1-14
- Maximum operating temperature of 60°C maintains structural integrity under elevated temperature conditions
- Inherently hydrophobic surface excels in organic-based, highly acidic or basic sample clarification
- Aqueous solution compatibility achieved through alcohol pre-wetting protocols when required
- HPLC-certified PTFE membrane with polypropylene support ensures analytical-grade performance
Key Tri-Layer Construction Characteristics
- Tri-layer design with glass microfiber and polypropylene prefilters raises absorption capacity for viscous and turbid liquid processing
- Glass fiber prefilter protects membrane from early clogging and increases total filtration throughput capacity
- Female Luer-Lock inlet with male Luer-slip outlet provides secure, leak-tight syringe connections
- Ultrasonically bonded construction eliminates adhesive contamination while ensuring reliable seal integrity
- Polypropylene housing delivers broad chemical compatibility with harsh solvents, acids, and bases
LE-IWT-ES10410 filters achieve outstanding unit-to-unit reproducibility with clearly inscribed media identification for reliable analytical protocols. Tri-layer construction processes three to seven times more sample volume than standard syringe filters, maximizing your laboratory productivity during high-volume sample preparation campaigns. Optimized for HPLC and GC sample preparation prior to injection, these filters deliver consistent performance for chromatographic analysis, organic solvent clarification, and aggressive chemical filtration applications requiring validated analytical accuracy.
