Nylon Syringe Filters - SF18212

Featuring naturally hydrophilic nylon membrane technology with an integrated prefilter for enhanced particulate removal and sample clarification. Pre-sterilized filters deliver reliable performance through 0.45µm pores, optimizing sample preparation for analytical applications. Robust polypropylene construction ensures chemical compatibility while maintaining structural integrity across diverse laboratory workflows.

Key Nylon Membrane Characteristics

• Naturally hydrophilic membrane enables immediate filtration of aqueous samples without pre-wetting
• Precision-controlled 0.45µm pore size effectively removes particulates while preserving dissolved analytes
• Moderate bubble point of 23.0psi confirms consistent pore structure and membrane integrity
• Excellent chemical compatibility with aqueous non-acidic solutions and compatible organic solvents
• Uniform 90-120µm membrane thickness provides stable flow rates and reliable particle retention

Key Construction Characteristics

• Integrated PP prefilter captures coarse particles, extending primary membrane life significantly
• Ultra-low holdup volume of 20µl maximizes recovery of valuable samples in small-scale applications
• Dual Luer-Lok inlet and Luer slip outlet connections ensure secure attachment to standard syringes
• Withstands operating pressures up to 87psi for consistent performance with viscous samples

SF18212 syringe filters provide the precise filtration performance your laboratory demands for critical sample preparation. Pre-sterilized convenience combined with an integrated prefilter design ensures your analytical workflows proceed efficiently while maintaining data quality. Optimal 17mm diameter configuration allows your team to process small to medium sample volumes with minimal holdup, maximizing recovery of precious materials.
