Hydrophilic PTFE Syringe Filter, Sterile, 0.45µm, 25mm, Luer Lock, HPLC Ready, 100/Pk SKU: LE-IWT-ES10042

Featuring hydrophilic PTFE membrane technology delivering superior chemical compatibility for aggressive solvents, acids, and bases while maintaining sterile filtration integrity. Modified hydrophilic PTFE construction provides exceptional chemical compatibility and pH resistance suitable for aqueous solutions, aggressive organic solutions, and high temperature solutions. Advanced hydrophilic surface treatment eliminates pre-wetting requirements when filtering aqueous solutions, accelerating sample preparation workflows for HPLC, GC, and chromatography applications requiring validated sterility.

Key PTFE Membrane Characteristics

• 0.45µm absolute-rated pore structure delivers precise particulate retention while maximizing flow rates for viscous organic samples
• Gamma irradiation sterilization with controlled dosimetry and spore strip validation ensures lot-to-lot sterility assurance
• Hydrophilic surface modification enables direct aqueous filtration without alcohol pre-wetting, reducing sample dilution and preparation time
• Excellent biosafety with chemical inertness and low adsorption characteristics for high-temperature liquid filtration applications
• Superior solvent resistance withstands alcohols, aromatics, aggressive solvents, strong acids, and bases without membrane degradation

Key Construction Characteristics

• Premium polypropylene housing with over-molded design ensures higher operating pressures and wide chemical compatibility
• Luer lock inlet and outlet connections provide leak-tight syringe connections for reliable sample processing
• Individual blister packaging maintains sterility while enabling convenient single-unit dispensing for contamination control
• 25mm diameter optimizes filtration area for enhanced throughput while accommodating standard syringe volumes
• Polypropylene housing withstands maximum operating temperatures to 180°C and enables autoclave sterilization protocols

LE-IWT-ES10042 filters achieve exceptional unit-to-unit and lot-to-lot reproducibility essential for quantitative analytical protocols, while the unique concentric funnel-shaped barrel design decreases back pressure and permits optimal utilization of small sample volumes. Outstanding chemical compatibility for harsh solvents that destroy other membrane materials maximizes analytical flexibility when processing challenging samples requiring both sterile filtration and validated performance. Wide applications across medicine, biochemistry, microelectronics, and environmental protection with standard interfaces compatible with various syringes and direct connection to analytical instrumentation transforms these filters into essential tools for your critical sample preparation demanding both chemical resistance and sterile processing capabilities.
