PTFE Syringe Filter, Hydrophobic, Nonsterile, 0.22µm, 25mm, Luer-Lok, 100/Pk SKU: LE-IWT-ES10019

Featuring hydrophobic PTFE membrane technology providing exceptional chemical resistance and solvent compatibility for demanding organic filtration applications. Advanced 0.22µm pore structure delivers reliable particulate removal while maintaining superior flow characteristics through aggressive solvents, acids, and bases. Polypropylene housing construction withstands harsh chemical environments and ultrasonically bonded assembly ensures leak-tight performance during high-pressure organic sample processing.

Key PTFE Membrane Characteristics

• Hydrophobic surface chemistry repels aqueous solutions while optimizing flow rates through nonpolar organic solvents and chromatography mobile phases
• Exceptional chemical compatibility resists aggressive organics, strong acids, and caustic solutions without membrane degradation or extractable contamination
• 0.22µm absolute pore rating removes fine particulates and contaminants from viscous HPLC samples and analytical standards
• Superior solvent resistance maintains structural integrity when processing alcohols, ketones, and aromatic compounds for GC/MS applications
• Low extractables profile preserves sample purity during trace analysis and eliminates interference in sensitive analytical protocols

Key Construction Characteristics

• 25mm diameter membrane maximizes filtration area while accommodating standard syringe volumes from 1mL to 60mL capacity ranges
• Durable polypropylene housing delivers chemical inertness and dimensional stability under pressure differentials up to operating limits
• Female Luer-Lok inlet connection ensures secure syringe attachment while male Luer slip outlet accommodates diverse laboratory equipment configurations
• Ultrasonically welded construction eliminates adhesives and creates permanent leak-tight seals resistant to solvent penetration
• Autoclavable design supports 121°C steam sterilization for 15 minutes when sterile processing protocols require validated decontamination procedures

LE-IWT-ES10019 filters excel in HPLC sample preparation and chromatography solvent degassing applications, accelerating your analytical workflows through consistent 25mm filtration area performance. Pre-wetting with alcohol enables aqueous solution processing while maintaining the inherent hydrophobic characteristics essential for organic solvent compatibility. Nonsterile configuration provides cost-effective filtration for routine analytical applications while delivering the chemical resistance and flow optimization demanded by modern analytical laboratories processing diverse organic matrices.
