PTFE Hydrophobic Syringe Filter, 0.45µm, 13mm, Nonsterile, Luer-Lock, 100/Pk SKU: LE-IWT-ES10018

Featuring hydrophobic PTFE membrane technology delivering superior chemical resistance for demanding solvent filtration applications. The 0.45µm pore structure provides precise particle retention while maintaining exceptional compatibility with aggressive organic solvents, acids, bases, and harsh chemicals. Ultrasonically bonded construction with Luer-Lock™ connectivity ensures reliable, leak-proof operation during HPLC sample preparation, chromatography solvent filtration, and aerosol sampling protocols.

Key PTFE Membrane Characteristics

• Inherently hydrophobic PTFE membrane resists water-based interference while optimizing nonpolar liquid and gas filtration efficiency
• Exceptional solvent resistance withstands aggressive organic compounds, acids, and bases without degradation or contamination
• 0.45µm absolute pore rating captures fine particulates while maintaining high flow rates for viscous organic-based samples
• FDA 21 CFR 177.1550 compliant¹ PTFE construction ensures material safety for food contact and pharmaceutical applications
• Convertible hydrophobic surface becomes hydrophilic after alcohol pre-wetting for aqueous solution compatibility

Key Construction Characteristics

• Ultrasonically bonded assembly eliminates adhesive contamination while providing superior seal integrity under pressure
• Polypropylene housing delivers broad chemical compatibility and withstands temperatures up to 60°C for thermal stability
• Luer-Lock™ inlet with pressure fitting accommodation ensures secure syringe connection and prevents sample loss
• 13mm diameter configuration optimizes filtration area for standard analytical volumes while minimizing holdup volume
• Concentric funnel-shaped barrel increases sample volume capacity while reducing back pressure during filtration

LE-IWT-ES10018 filters achieve outstanding unit-to-unit and lot-to-lot reproducibility, maximizing your analytical consistency across extended sampling campaigns. The unique barrel design accelerates processing of viscous HPLC samples while the clearly inscribed filter media identification prevents costly mix-ups during multi-sample workflows. Ideal for chromatography solvent degassing, vacuum pump line protection, and moisture barrier venting applications where exceptional chemical resistance transforms routine filtration challenges into validated analytical advantages.
