PTFE Syringe Filter w/ Glass Fiber Prefilter, 0.45µm, 13mm, Luer-Lock, Nonsterile, 100/Pk SKU: LE-IWT-ES10194

Featuring hydrophobic PTFE membrane technology with integrated glass microfiber prefilter delivering exceptional chemical resistance and extended service life for demanding analytical applications. The glass fiber prefilter reduces particle loading experienced by the membrane final filter and extends service life, providing greater total throughput for fluids containing high levels of suspended solids. Ultrasonically bonded construction with concentric funnel-shaped barrel design optimizes volume capacity while minimizing back pressure during sample processing.

• Hydrophobic 0.45µm pore size delivers precise filtration of nonpolar liquids, gases, and organic solvents with superior chemical compatibility
• Exceptional resistance to acids, bases, and harsh chemicals makes this ideal for aggressive sample matrices and chromatography applications
• Ultrasonically bonded membrane construction ensures reliable unit-to-unit and lot-to-lot reproducibility for consistent analytical results
• Low extractables profile minimizes sample contamination during HPLC sample preparation and viscous organic-based analyses
• Pre-wetting capability with alcohol enables fine particle removal from aqueous and mild organic solutions in ion chromatography protocols

• Integrated glass microfiber prefilter extends membrane life by capturing larger particulates before they reach the primary filtration media
• Compact 13mm diameter with Luer-Lock and pressure fitting accommodates standard laboratory syringes and automated sampling equipment
• Concentric funnel-shaped barrel increases sample volume capacity while decreasing back pressure for improved flow characteristics
• Clearly inscribed filter media identification on barrel ensures proper filter selection and regulatory compliance documentation
• Nonsterile configuration optimized for routine analytical applications requiring chemical compatibility over sterility requirements

These filters excel in chromatography solvent degassing, aerosol sampling, and vacuum pump line protection applications where chemical resistance is paramount. Outstanding compatibility with HPLC mobile phases accelerates your sample preparation workflows while providing reliable moisture barrier properties for venting applications. The dual-layer filtration system maximizes throughput capacity, making these filters ideal for high-volume laboratories processing challenging sample matrices requiring both coarse particle removal and fine filtration in a single step.
