Polypropylene (PP) Syringe Filters - SF18218

Small-volume pharmaceutical and biological workflows face persistent challenges balancing rapid particulate removal with maximum sample recovery while maintaining sterile processing conditions throughout analytical preparation. Excessive holdup volumes and slow flow rates compromise precious sample yields, creating bottlenecks in quality control testing and research applications. Gamma-sterilized 0.45µm polypropylene membrane technology resolves these limitations through compact 13mm platform design that delivers efficient clarification with exceptional sample preservation. Technical specifications include validated 7.40psi bubble point ensuring consistent particulate retention, 1.09cm² filtration area, and minimal 20µL holdup volume supporting 11ml flow rate with 10ml throughput capacity for economical small-volume processing.

Key Polypropylene Membrane Characteristics

Clarification-focused 0.45µm architecture removes particulates from biological and pharmaceutical samples while maintaining rapid processing rates for small-volume workflows
Gamma-sterilized, ready-to-use design provides contamination control throughout sample handling without bacterial retention specifications for pharmaceutical applications
Hydrophobic membrane structure requires pre-wetting with a compatible organic solvent before aqueous filtration, establishing flow pathways through the polypropylene matrix
Economical construction supports cost-effective routine clarification operations while maintaining consistent performance across compatible chemical environments
Selective chemical resistance maintains compatibility with acids, bases, and aqueous solutions after proper pre-wetting, while being incompatible with esters

Key Construction Characteristics

Minimal 20µL holdup volume maximizes recovery of valuable samples during 1-10ml processing, where every microliter directly impacts analytical precision and project economics
Compact 13mm platform provides space-efficient clarification for small-volume applications with 11ml flow rate performance at 87psi maximum operating pressure
Universal Luer-Lok/Luer Slip interface eliminates adapter requirements, enabling rapid connections with standard laboratory syringes for streamlined workflow integration
Moderate-temperature polypropylene housing operates reliably up to 60°C maximum temperature, accommodating ambient and slightly elevated processing conditions

Built to support your small-volume clarification requirements where sample recovery cannot be compromised, gamma-sterilized construction delivers dependable performance. Validated 7.40psi bubble point provides operational confidence throughout pharmaceutical workflows. Minimal holdup design combined with compact platform geometry ensures your laboratory operations maintain both efficiency and economy across diverse applications requiring sterile particulate removal.
