Nylon Syringe Filters, 3.0um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF14903

Nylon Syringe Filters - SF14903

Featuring naturally hydrophilic nylon membrane technology with an integrated prefilter for effective coarse filtration and rapid sample processing. The pre-sterilized filters deliver exceptional flow rates through 3.0µm pores, optimizing the clarification of viscous samples and particulate-laden solutions. Robust polypropylene construction ensures chemical resistance while maintaining dimensional stability throughout demanding filtration procedures.

Key Nylon Membrane Characteristics

• Naturally hydrophilic membrane enables immediate aqueous sample filtration without pre-wetting requirements
• Coarse 3.0µm pore size removes larger particulates while preserving dissolved components
• Moderate bubble point allows the gentle processing of temperature-sensitive laboratory samples
• Excellent chemical compatibility with aqueous non-acidic solutions and compatible organic solvents
• Uniform 90-120µm membrane thickness delivers consistent retention and stable flow characteristics

Key Construction Characteristics

• Integrated PP prefilter captures extra-large particles, significantly extending primary membrane life
• Minimal holdup volume of 100µl preserves valuable samples and reduces material waste
• Dual Luer-Lok inlet and Luer slip outlet connections provide secure attachment to standard syringes
• Withstands operating pressures up to 87psi for reliable performance with challenging samples

SF14903 syringe filters deliver the high-flow coarse filtration performance your laboratory demands for challenging sample matrices. The pre-sterilized format combined with an exceptional 240ml/minute flow rate ensures your team processes large volumes efficiently while protecting downstream equipment. Optimized 25mm configuration with integrated prefilter provides your workflows with the rapid clarification necessary for maintaining productivity in high-throughput analytical environments.

• Coarse Prefiltration - Removes large particulates to extend the life of downstream fine filters in sterile filtration protocols
• Dissolution Media Clarification - Removes coarse tablet fragments from dissolution samples to ensure accurate analytical measurement
• Environmental Sample Processing - Clarifies turbid water samples to prevent clogging during subsequent fine filtration or testing
• Viscous Solution Filtration - Facilitates the filtration of difficult, viscous fluids without clogging using the large 3.0µm pore size
• Particle Fractionation - Separates particles above 3.0µm from the solution to enable precise particle size distribution analysis
• Industrial Sample Preparation - Clarifies manufacturing samples for quality control using a pre-sterilized unit to ensure purity
