Polypropylene Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18220

Polypropylene (PP) Syringe Filters - SF18220

Precision 0.45µm polypropylene membrane technology on an ultra-compact 4mm platform delivers economical clarification for micro-volume applications, featuring gamma-sterilized construction with 0.125cm² filtration area optimized for sub-milliliter sample processing. Hydrophobic characteristics accommodate organic solvent compatibility after pre-wetting. Validated 7.40psi bubble point ensures consistent particulate retention across pharmaceutical quality control, biological micro-sample preparation, and analytical workflows requiring absolute contamination control with exceptional sample preservation through minimal 1µL holdup design for critical micro-volume applications.

Key Polypropylene Membrane Characteristics

Micro-volume clarification efficiently removes particulates from sub-milliliter samples while 0.45µm architecture maintains processing rates appropriate for critical small-scale workflows
Gamma-sterilized, ready-to-use platform provides contamination control for pharmaceutical micro-sampling without bacterial retention specifications in routine quality testing
Economical polypropylene construction supports cost-effective micro-volume operations while maintaining consistent performance across compatible chemical environments
Hydrophobic membrane platform processes organic solvents and non-aqueous solutions after a compatible solvent pre-wetting establishes flow pathways through the membrane architecture
Selective compatibility range withstands acids, bases, and aqueous solutions following proper pre-wetting, while avoiding esters that degrade polypropylene structure

Key Construction Characteristics

Ultra-minimal 1µL holdup volume preserves precious micro-volume samples where every microliter represents significant analytical value and experimental investment
Ultra-compact 4mm platform provides space-efficient clarification for sub-milliliter applications with 1ml flow rate performance at 87psi maximum operating pressure
Universal Luer-Lok/Luer Slip interface integrates seamlessly with micro-volume syringes, eliminating adapter requirements and simplifying workflow integration
Moderate-temperature polypropylene housing maintains structural integrity up to 60°C maximum temperature for ambient and slightly elevated micro-processing conditions

When your micro-volume workflows demand maximum sample preservation with sterile contamination control, gamma-sterilized polypropylene construction delivers exceptional performance. Validated 7.40psi bubble point provides operational confidence throughout pharmaceutical micro-sampling. Ultra-minimal holdup design combined with compact platform geometry ensures your laboratory operations maintain both efficiency and economy across diverse applications requiring critical micro-volume sterile particulate removal capabilities.
