Hydrophilic PTFE Syringe Filter, 0.45µm, 13mm, Sterile, Luer-Lok, HPLC Grade - 100/Pk SKU: LE-IWT-ES10040

Featuring hydrophilic polytetrafluoroethylene (PTFE) membrane technology delivering exceptional chemical compatibility for aggressive solvents and extreme pH conditions from 1-14. Modified hydrophilic PTFE construction provides superior resistance to organic solutions and high temperature applications while eliminating the need for pre-wetting with alcohol when filtering aqueous solutions. Maximum operating temperature of 60°C with 0.45µm pore size delivers reliable particulate retention for HPLC sample preparation, chromatography solvent filtration, and viscous organic-based analytical protocols.

Key Hydrophilic PTFE Membrane Characteristics

• Hydrophilic surface modification enables direct filtration of aqueous solutions without alcohol pre-wetting requirements
• Outstanding chemical inertness withstands aggressive solvents, strong acids, and alkaline solutions for versatile sample processing
• Low extractables profile maintains sample integrity during HPLC and GC analysis applications requiring contamination-free results
• Superior flow characteristics optimize filtration speed while maintaining consistent 0.45µm particulate retention efficiency
• Excellent unit-to-unit reproducibility ensures reliable performance across analytical batches and quality control protocols

Key Construction Characteristics

• Premium polypropylene housing delivers broad chemical compatibility with harsh solvents and extreme pH conditions
• Luer-Lok inlet connection with pressure fitting design provides secure, leak-resistant syringe attachment during filtration
• Individual sterile blister packaging maintains sterility integrity while facilitating contamination-free handling protocols
• Ultrasonic bonding construction eliminates adhesive contamination risks while ensuring reliable membrane-to-housing seal integrity
• Concentric funnel-shaped barrel design increases sample volume capacity while reducing back pressure for optimal small-volume processing

These 13mm diameter filters achieve optimal sample throughput with minimal hold-up volume, accelerating your analytical workflows while maintaining sterility assurance for pharmaceutical and biotechnology applications. Clear filter media identification markings inscribed on each barrel eliminate selection errors during multi-sample processing protocols. Exceptional lot-to-lot consistency combined with gamma sterilization validation delivers the performance reliability demanded for critical HPLC sample preparation, aerosol sampling, and organic solvent degassing applications requiring both chemical resistance and sterile filtration capabilities.
