Sterile PTFE Syringe Filter, 0.45µm, 25mm, Hydrophobic, Luer-Lok, HPLC Grade, 100/Pk SKU: LE-IWT-ES10027

Featuring hydrophobic PTFE membrane technology delivering exceptional chemical resistance and sterile filtration performance for demanding analytical applications. Low-binding PTFE membrane construction provides leachable-free filtration with pH compatibility from 1-14, while 0.45µm pore size ensures reliable particulate retention for HPLC sample preparation, chromatography solvents, and aggressive organic solutions. Sterile processing with ultrasonically bonded housing maintains contamination-free integrity throughout critical analytical workflows.

• Hydrophobic polytetrafluoroethylene construction resists moisture interference and enables gas filtration applications
• 0.45µm pore rating captures fine particulates while maintaining optimal flow rates for viscous organic samples
• Exceptional chemical compatibility withstands harsh solvents, acids, and bases without membrane degradation
• Ultra-low extractables design minimizes chromatographic interference in sensitive HPLC and GC analysis protocols
• Sterile filtration capability supports pharmaceutical sample preparation and biological fluid processing applications

• 25mm diameter with female Luer-Lok inlet and male slip outlet accommodates standard syringe configurations
• Ultrasonically bonded polypropylene housing ensures leak-free operation under pressure while resisting solvent attack
• FDA 21 CFR 177.1520 compliant polypropylene construction validates food contact applications and pharmaceutical processing
• Concentric funnel-shaped barrel design increases filtration volume capacity while reducing back pressure during operation
• Clear filter media identification markings on barrel eliminate confusion during multi-sample processing workflows

LE-IWT-ES10027 filters achieve outstanding unit-to-unit and lot-to-lot reproducibility, accelerating your analytical throughput while maintaining consistent results across extended sampling campaigns. HPLC compatibility testing with established procedures confirms low UV-detectable extractables for sensitive analytical applications. After alcohol pre-wetting, these versatile filters transition to hydrophilic behavior for aqueous and mild organic solutions in ion chromatography, maximizing your analytical flexibility across diverse sample matrices requiring both sterile processing and validated performance assurance.
