PTFE Hydrophobic Syringe Filter, 0.22µm, 17mm, Glass Prefilter, Nonsterile, 100/Pk SKU: LE-IWT-ES10320

Featuring hydrophobic PTFE membrane technology with integrated glass microfiber prefilter delivering superior chemical resistance and particle retention for demanding solvent-based applications. The 0.22µm pore configuration provides reliable filtration of aggressive organic substances, highly basic solutions, and hot liquids while maintaining broad chemical compatibility across pH 1-14. Polypropylene housing construction withstands maximum operating temperatures up to 180°C, optimizing performance for HPLC sample preparation and chromatography solvent filtration protocols.

Key PTFE Membrane Characteristics

• Native chemically inert hydrophobic PTFE membrane construction delivers exceptional chemical compatibility for harsh solvents, acids, and bases
• 0.22µm absolute pore rating ensures consistent particle removal while maintaining optimal flow rates for viscous organic samples
• Capable of filtering aqueous solutions following pre-wetting with alcohol, expanding application versatility beyond nonpolar solvents
• Ideal for venting and gas filtration applications plus clarification and sterilization of organic solutions
• Eliminates interfering materials and fine particles down to the specified pore size for cleaner sample extracts

Key Construction Characteristics

• Glass fiber prefilter reduces particle loading on the membrane and extends service life for high-solids samples
• Premium polypropylene housing with over-molded design ensures higher operating pressures and wide chemical compatibility
• Luer-Lock inlet connection offers leak-tight syringe attachment with reliable sealing during filtration
• 17mm diameter provides increased filtration area compared to smaller formats, offering greater filtration volume capacity
• Rugged construction enables autoclaving to 121°C for 15 minutes when sterilization protocols require it

LE-IWT-ES10320 filters deliver exceptional performance for HPLC mobile phase preparation, organic solvent degassing, and viscous sample clarification applications. These versatile filters excel with aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation. The integrated prefilter design maximizes membrane life while the hydrophobic PTFE technology ensures reliable processing of nonpolar liquids, gases, and moisture-sensitive applications requiring validated filtration performance.
