Polypropylene (PP) Syringe Filters - SF18306

Particulate-laden samples frequently overwhelm standard clarification filters, causing rapid fouling that reduces throughput and increases processing costs in routine pharmaceutical and biological workflows requiring sustained flow rates. Single-layer membranes lack the capacity to handle high dirt-load applications efficiently, creating bottlenecks in quality control and research laboratories. Multi-stage 0.45µm polypropylene technology resolves these limitations through three-layer prefiltration combining polypropylene and glass fiber elements that capture gross debris before the final membrane. Technical architecture includes validated 7.40psi bubble point ensuring consistent particulate retention, 25mm platform with 4.08cm² filtration area, and autoclavable construction supporting 35ml flow rate with 50ml throughput capacity for economical extended-capacity clarification.

Key Polypropylene Membrane Characteristics

High-capacity 0.45µm clarification removes particulates from challenging sample matrices while three-stage prefiltration extends operational life by protecting the final membrane from premature fouling
Autoclavable polypropylene platform enables in-house sterilization at 121°C for 30 minutes, allowing users to customize sterilization protocols and reduce inventory management complexity
Hydrophobic membrane architecture requires pre-wetting with a compatible organic solvent before aqueous sample processing, establishing continuous flow pathways through the membrane structure
Three-layer prefiltration system combines polypropylene and glass fiber materials that progressively capture particulates, enabling sustained processing of dirty biological and pharmaceutical samples
Economical multi-stage construction delivers cost-effective extended-capacity filtration for routine high-particulate workflows while maintaining consistent performance across compatible chemical environments

Key Construction Characteristics

Enhanced 400µL holdup volume accommodates multi-layer design while supporting 10-100ml processing, where extended throughput capacity justifies slightly increased sample retention
Thermally stable housing maintains structural integrity up to 60°C maximum operating temperature for ambient and moderately elevated processing applications
Versatile Luer-Lok/Luer Slip interface provides compatibility with standard laboratory syringes, eliminating adapter requirements and simplifying workflow integration
Generous 4.08cm² filtration area sustains exceptional 35ml flow rate at 87psi maximum operating pressure despite challenging high-particulate sample compositions

Built to support your high-particulate clarification requirements where standard filters fail prematurely, multi-layer prefiltration technology delivers extended processing capacity. Validated 7.40psi bubble point maintains structural integrity throughout demanding workflows. Autoclavable construction combined with enhanced dirt-load capability ensures your laboratory operations achieve both efficiency and economy across diverse applications requiring sustained clarification of challenging samples.
