PTFE Syringe Filter w/ Glass Fiber Prefilter, Sterile, 0.45µm, 25mm, 100/Pk SKU: LE-IWT-ES10201

Featuring hydrophobic PTFE membrane technology with integrated glass microfiber prefilter delivering exceptional filtration performance for chromatography solvents, nonpolar liquids, and gas phase applications. The 0.45µm pore size configuration provides reliable particulate retention while the glass fiber prefilter reduces the particle loading experienced by the membrane final filter and, consequently, extends the service life. Sterile construction with Luer-Lok® compatibility ensures contamination-free processing for critical analytical protocols requiring validated sample preparation.

• Hydrophobic PTFE construction delivers superior chemical resistance to acids, bases, and organic solvents for versatile analytical applications
• For applications with fluids containing high levels of suspended solids, the incorporated glass fiber prefilter provides greater total throughput compared to filters without prefilters
• Inherently hydrophobic surface chemistry optimizes filtration of nonpolar liquids, chromatography solvents, and gas phase samples
• Low extractable design minimizes sample contamination for HPLC, GC, and ion chromatography applications
• Maximum recommended operating temperature of 60°C accommodates heated sample processing protocols

• Sterile packaging eliminates microbial contamination risk for pharmaceutical and biotechnology sample preparation
• 25mm diameter with optimized filtration area balances flow rate performance with handling convenience
• Ultrasonically bonded housing construction provides leak-free operation under pressure differentials
• Female Luer-Lok inlet and male Luer slip outlet ensure secure connections with standard syringes and equipment
• Concentric funnel-shaped barrel design increases filterable volume while reducing back pressure during filtration

These filters achieve exceptional performance for aerosol sampling, vacuum pump line protection, and moisture barrier venting applications while maintaining consistent unit-to-unit and lot-to-lot reproducibility. Pressure rating of 90psi enables reliable operation under demanding filtration conditions. After pre-wetting with alcohol, filters become compatible with aqueous and mild organic solutions, maximizing your analytical flexibility for ion chromatography and fine particle removal applications requiring both sterile integrity and validated chemical compatibility.
