Trupor PES Syringe Filter, 0.45µm, 25mm, Hydrophilic, Nonsterile, Low Back Pressure, 100/Pk SKU: LE-IWT-ES20026

Featuring nanoscale fiber composite design technology delivering precisely regulated porosities for superior analytical separation performance. Binderless construction eliminates adhesives to significantly reduce trace extractables, making these filters ideal for critical HPLC, GC, and chromatography sample preparation applications. Advanced membrane architecture reduces back pressure by greater than 50% versus comparable cast membranes, minimizing operator fatigue while accelerating sample processing workflows.

Key PES Membrane Characteristics

• Nanoscale fiber composite technology achieves precisely regulated 0.45µm pore structure for consistent particle retention across device-to-device applications
• Hydrophilic polyethersulfone membrane provides broad chemical compatibility with aqueous and organic solvents commonly used in analytical testing
• Greater than 40% loading capacity increase versus comparable cast membranes allows processing of larger sample volumes with single filter units
• Equal or greater retention consistency to leading polymeric membranes ensures reproducible separation results from lot-to-lot
• Ultra-low extractables profile without adhesives or binders prevents sample contamination in trace analysis applications

Key Construction Characteristics

• Ultrasonically welded polypropylene housing eliminates dies, surfactants, and colorants that could interfere with analytical results
• Standard 25mm diameter with luer-lok/slip port compatibility accommodates universal syringe configurations and autosampler systems
• Reduced internal device pressures from low back pressure design minimize risk of sample-fouling integrity failure during filtration
• Nonsterile configuration optimized for routine analytical sample preparation where sterility is not required
• Manufactured in the United States ensuring consistent quality control and supply chain reliability for laboratory operations

Larger sample volumes can be prepared with one syringe filter, reducing sample preparation costs and decreasing waste disposal requirements while maintaining analytical precision. Class leading performance in low-backpressure and throughput volumes accelerates your laboratory workflows, particularly beneficial for high-volume sample processing in pharmaceutical, environmental, and quality control applications. The superior flow characteristics and consistent device-to-device performance provide confidence in critical separation applications where reproducible results are essential for regulatory compliance and method validation.
