Nylon Syringe Filters - SF04525NPS

SF04525NPS positively charged nylon syringe filters provide specialized electrostatic filtration technology engineered for laboratories requiring enhanced particle capture and sterile sample processing. These advanced 0.45μm syringe filters deliver superior retention efficiency for negatively charged contaminants. These syringe filters are particularly effective for clinical applications where both filtration effectiveness and microbiological safety are essential.

Key Nylon Membrane Characteristics

• Positively charged surface modification provides superior retention of negatively charged particles, bacteria, and endotoxins through electrostatic attraction
• Controlled membrane porosity ensures effective clarification of samples while maintaining adequate flow rates
• Excellent resistance to aqueous solutions, biological buffers, and polar organic solvents while preserving charge characteristics
• Dual filtration mechanism combining electrostatic attraction and mechanical filtration delivers superior removal of submicron contaminants and microorganisms
• Robust surface modification maintains positive charge characteristics throughout extended use and diverse sample processing conditions

Key Construction Characteristics

• Gamma-irradiated production ensures complete microbiological safety and eliminates contamination risks for sterile filtration applications
• Medical-grade polypropylene construction provides exceptional chemical inertness and resistance to laboratory solvent exposure
• Advanced sealing design ensures leak-proof operation and prevents bypass flow during critical sterile filtration procedures
• Standard luer connection design accommodates all common laboratory syringes and sterile sampling equipment
• Cleanroom manufacturing environment and rigorous testing protocols guarantee consistent performance and sterility validation

Tisch Scientific SF04525NPS positively charged nylon syringe filters deliver the dual benefits of mechanical and electrostatic filtration for superior microbial removal. If your laboratory requires specialized syringe filtration processes for microbiology, vaccine manufacturing, or other biotechnological processes, these positively charged and sterile syringe filters provide a cost-effective alternative to expensive name brands. These syringe filters enable laboratories to achieve exceptional sample purity and sterility assurance while maintaining operational efficiency for manufacturing applications, microbiological safety, and analytical reliability.
