Nylon Syringe Filters, Positive Charge, 0.45um, 25mm, Sterile, 50/Pk SKU: SF04525NPS

Nylon Syringe Filters - SF04525NPS

Featuring positively charged nylon membrane technology specifically engineered for endotoxin removal from water, buffers, and biological solutions. Pre-sterilized filters deliver effective clarification through 0.45µm pores while actively binding negatively charged contaminants. Advanced polypropylene construction ensures chemical stability and dimensional integrity throughout critical purification procedures.

Key Nylon Membrane Characteristics

• Positively charged surface actively binds and removes negatively charged endotoxins and pyrogens
• Naturally hydrophilic membrane requires no pre-wetting for immediate aqueous solution filtration
• Optimal 0.45µm pore size effectively removes particulates while maintaining excellent flow rates
• Moderate bubble point of 23.0psi confirms consistent pore distribution and membrane integrity
• Uniform 90-120µm membrane thickness provides reliable filtration performance across diverse samples
• Excellent chemical compatibility with aqueous non-acidic solutions and compatible organic solvents

Key Construction Characteristics

• Ultra-low holdup volume of 50µl minimizes sample loss and maximizes recovery efficiency
• Dual Luer-Lok inlet and Luer slip outlet connections provide secure attachment to standard syringes
• Robust polypropylene housing withstands 87psi operating pressure for consistent performance
• Compact 2.98cm² filtration area optimized for standard-volume endotoxin reduction applications

SF04525NPS syringe filters provide the specialized endotoxin reduction your laboratory requires for sensitive biological applications. Positively charged membrane technology combined with 0.45µm particle removal ensures your samples achieve both clarification and endotoxin reduction. Pre-sterilized convenience packaging allows your team to maintain workflow efficiency while meeting stringent endotoxin specifications for pharmaceutical and biotechnology applications.
