Polypropylene Syringe Filter, 0.45µm, 25mm, Hydrophobic, Nonsterile, Luer-Lock, 100/Pk SKU: LE-IWT-ES10131

Featuring hydrophobic polypropylene membrane technology providing excellent chemical compatibility with broad pH tolerance from 1 to 14, these disposable syringe filters deliver reliable particle removal and sample clarification for routine laboratory applications. Optimized for clarification and prefiltration ahead of membrane filters, the 0.45µm pore configuration captures particles larger than 0.45 microns while maintaining consistent flow rates through the concentric funnel-shaped barrel design. Ultrasonically bonded polypropylene construction within a matching polypropylene housing ensures chemical inertness and eliminates contamination risks during filtration protocols.
