Sterile PTFE Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 25mm, Hydrophobic, 100/pk SKU: LE-IWT-ES10200

Featuring dual-layer PTFE membrane technology with integrated glass microfiber prefilter delivering superior filtration performance for demanding chromatography and analytical applications. The glass fiber prefilter reduces the particle loading experienced by the membrane final filter and, consequently, extends the service life. A 0.22µm hydrophobic PTFE membrane with 25mm diameter provides precise particulate retention while maintaining optimal flow characteristics through viscous organic solvents and aggressive chemical matrices. Sterile packaging with Luer-Lok™ connections ensures contamination-free processing of HPLC samples, GC preparations, and critical biological specimens requiring validated sterile filtration protocols.

• Hydrophobic PTFE construction delivers exceptional chemical resistance to acids, bases, and organic solvents while preventing aqueous wetting
• 0.22µm absolute retention rating captures bacteria and fine particulates with 99.999% efficiency for sterile filtration applications
• For some applications with fluids containing high levels of suspended solids, a syringe filter with an incorporated glass fiber prefilter will usually have greater total throughput when comparted to one without a prefilter.
• Ultra-low extractables profile maintains sample integrity during trace analysis and prevents interference with sensitive detection methods
• Superior solvent compatibility enables processing of aggressive chromatography mobile phases and viscous organic matrices

• Glass microfiber prefilter extends service life by capturing coarse particulates before they reach the primary membrane
• Ultrasonically bonded polypropylene housing ensures leak-free operation while providing clear membrane identification markings
• Concentric funnel-shaped barrel design increases filtrate volume capacity while minimizing back pressure during high-viscosity sample processing
• Sterile gamma-irradiated packaging maintains bioburden-free conditions for pharmaceutical and biotechnology applications
• Luer-Lok™ inlet and pressure-compatible outlet fittings accommodate standard syringes and automated sampling equipment

LE-IWT-ES10200 filters achieve exceptional unit-to-unit reproducibility delivering consistent results across analytical batches, accelerating your laboratory workflows during routine HPLC sample preparation and chromatography mobile phase filtration. Outstanding chemical compatibility with nonpolar liquids and gases maximizes your analytical flexibility when processing diverse sample matrices from environmental extracts to pharmaceutical intermediates. Sterile construction transforms these filters into validated biocompatible media, providing performance assurance for your critical tissue culture applications, aerosol sampling protocols, and vacuum pump protection systems demanding both chemical resistance and guaranteed sterile performance.
