Nylon Syringe Filters, Positive Charge, 0.22 um, 25mm, Sterile, 50/Pk SKU: SF02225NPS

Nylon Syringe Filters - SF02225NPS

Featuring positively charged nylon membrane technology specifically engineered for endotoxin removal from water, buffers, and biological solutions. Sterile filters deliver exceptional bacterial retention through 0.22µm pores while maintaining ultra-low endotoxin levels. Advanced polypropylene construction ensures chemical stability and dimensional integrity throughout demanding purification protocols.

Key Nylon Membrane Characteristics

• Positively charged surface actively binds and removes negatively charged endotoxins from biological samples
• Naturally hydrophilic membrane requires no pre-wetting for immediate aqueous solution filtration
• Precision-controlled 0.22µm pore size guarantees complete bacterial removal for sterile applications
• High bubble point of 37.5psi validates membrane integrity and consistent pore size distribution
• Uniform 90-120µm membrane thickness provides reliable flow characteristics and bacterial retention
• 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 precious samples requiring minimal volume processing

SF02225NPS syringe filters provide the specialized endotoxin removal your laboratory requires for critical biological applications. Positively charged membrane technology combined with 0.22µm bacterial retention ensures your sensitive samples remain sterile and endotoxin-free. Pre-sterilized convenience packaging allows your team to maintain workflow efficiency while meeting stringent purity requirements for pharmaceutical and biotechnology applications.,
