Trupor® PES Nanofiber Membrane, 0.45µm, 47mm, Hydrophilic, Binderless, 100/Pk SKU: LE-TPES-045047

Featuring revolutionary nanofiber composite technology delivering superior filtration performance compared to traditional cast film membranes. Binderless construction eliminates adhesives to significantly reduce trace extractables, creating an ideal matrix for analytical separations requiring ultra-clean sample preparation. Manufactured in the United States using precisely controlled composite layering that achieves optimized porosity regulation while maintaining exceptional membrane integrity throughout extended filtration cycles.

Key Nanofiber Membrane Characteristics

• Superior back pressure reduction exceeding 50% versus comparable cast membranes minimizes operator fatigue and reduces sample-fouling integrity failures
• Enhanced loading capacity exceeding 40% versus traditional cast membranes enables processing of larger sample volumes with single filter use
• Hydrophilic polyethersulfone construction with low protein binding characteristics maximizes sample recovery for biological and pharmaceutical applications
• Broad chemical compatibility across pH 1-14 range withstands aggressive solvents, acids, and bases without membrane degradation
• Precision pore uniformity delivers equal or greater consistency versus leading cast film membranes ensuring reproducible device-to-device performance

Key Construction Characteristics

• 0.45µm pore size configuration optimized for particulate retention while maintaining high throughput for aqueous solutions
