Nylon Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18213

Nylon Syringe Filters - SF18213

Featuring naturally hydrophilic nylon membrane technology with integrated prefilter for precise microscale filtration and sample clarification. Sterile filters deliver controlled performance through 0.45µm pores, optimizing sample preparation for precious or limited-volume analytical applications. Ultra-compact polypropylene construction ensures chemical resistance while maintaining dimensional stability in demanding microscale procedures.

Key Nylon Membrane Characteristics

• Naturally hydrophilic membrane allows immediate aqueous sample filtration without pre-wetting requirements
• Optimal 0.45µm pore size effectively removes particulates while preserving dissolved analytes
• Moderate bubble point of 23.0psi confirms uniform pore distribution and membrane integrity
• Superior chemical tolerance except for concentrated acids, aggressive organics, and protein solutions
• Consistent 90-120µm membrane thickness provides reliable filtration performance for small volumes

Key Construction Characteristics

• Integrated PP prefilter captures coarse particles, extending primary membrane life in microscale applications
• Ultra-minimal holdup volume of 1µl ensures maximum recovery of precious microscale samples
• Dual Luer-Lok inlet and Luer slip outlet connections provide secure attachment despite compact size
• Withstands operating pressures up to 87psi for reliable performance with limited sample volumes

SF18213 syringe filters deliver the precise microscale filtration your laboratory requires for irreplaceable or volume-limited samples. Pre-sterilized convenience combined with an integrated prefilter design ensures your team processes precious materials efficiently without sample loss. Microscale 4mm configuration with minimal holdup volume maximizes your recovery of valuable samples while providing the particle removal essential for protecting sensitive analytical instrumentation.
