PTFE Syringe Filter, Hydrophilic, 0.22µm, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: LE-IWT-ES10034

Featuring surface-modified hydrophilic PTFE membrane technology delivering immediate aqueous sample processing without pre-wetting requirements. Advanced hydrophilic PTFE membrane technology at 0.22µm pore size eliminates pre-wetting obstacles through surface-modified fluoropolymer chemistry that ensures immediate aqueous wetting, while maintaining exceptional chemical resistance to aggressive solvents, acids, and bases. Rugged polypropylene housing supports autoclavable construction to 121°C for 15 minutes, enabling flexible sterilization protocols for critical analytical applications.

Key PTFE Membrane Characteristics

Surface-modified hydrophilic chemistry filters water-based solutions without the necessity of pre-wetting with alcohol
Universal membrane design provides ideal performance for both aqueous and organic samples with strong chemical stability
pH range compatibility from 1-14 ensures broad analytical flexibility for acidic and alkaline sample matrices
0.22µm absolute retention rating delivers reliable particulate removal and bacterial filtration for sterile sample preparation
Enhanced particle retention removes interfering substances and fine particles down to designated pore size for cleaner sample extracts

Key Construction Characteristics

Luer-Lok inlet connection offers leak-tight syringe attachment with secure mechanical interface
Polypropylene microfiber pre-filter layer improves filtration performance for particulate-laden fluid processing
13mm diameter with 0.092 cm² effective filtration area optimizes flow characteristics for small sample volumes
Color-coded and clearly labeled membrane identification enables rapid filter selection and reduces processing errors
Polypropylene housing construction delivers excellent chemical stability and compatibility with diverse sample matrices

LE-IWT-ES10034 filters optimize sample throughput in HPLC applications, chromatography solvent filtration, and analytical sample preparation requiring immediate processing without pre-wetting delays. Applications include HPLC, organic solvent sample preparation and cleanup, dissolution sample analysis, general sample preparation, and samples subjected to high temperatures or in caustic or acidic environments. Outstanding chemical compatibility with aggressive solvents maximizes your analytical flexibility while 100-count packaging delivers cost-effective processing for high-volume laboratory workflows demanding both chemical resistance and immediate sample processing capabilities.
