Nylon Syringe Filters, Positive Charge, 0.22 um, 25mm, Nonsterile, 100/Pk SKU: SF02225NP

Nylon Syringe Filters - SF02225NP

Featuring positively charged nylon membrane technology specifically engineered for endotoxin removal from water, buffers, and biological solutions. Nonsterile filters deliver exceptional bacterial retention through 0.22µm 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
• Precision-controlled 0.22µm pore size guarantees complete bacterial removal for sterilizing filtration
• Exceptional bubble point of 37.5psi validates membrane integrity and uniform pore distribution
• Uniform 90-120µm membrane thickness provides reliable bacterial retention and flow stability

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

SF02225NP syringe filters provide the specialized endotoxin reduction your laboratory requires for sensitive biological applications. Positively charged membrane technology combined with 0.22µm bacterial retention ensures your samples achieve both sterilization and endotoxin reduction. Autoclavable or gamma-sterilizable design allows your team to prepare custom sterile units while maintaining workflow efficiency for pharmaceutical and biotechnology applications.
