PVDF Syringe Filters, 0.22um, 4mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18227

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18227

Pharmaceutical and analytical laboratories demand sterilization technology capable of processing micro-volume precious samples with maximum recovery while maintaining validated bacterial retention across organic solvent systems and aggressive chemical environments encountered in high-value analytical testing and pharmaceutical development workflows. Advanced polyvinylidene fluoride membrane technology with 0.22 µm pore size and ultra-low 1 µL holdup volume delivers sterile-grade bacterial elimination through compact 0.125 cm² filtration area specifically engineered for volumes less than 1 ml. Furthermore, the 4mm diameter configuration with sterile packaging enables contamination-free processing of expensive analytical standards, rare biological compounds, and limited-availability research materials, making this design ideal for pharmaceutical quality control and research applications requiring both microbial control and sample conservation with aseptic handling capabilities.

Key PVDF Membrane Characteristics

Hydrophobic surface requires pre-wetting with alcohols or compatible organic solvents before aqueous processing, optimizing performance for micro-volume sterile pharmaceutical preparations
0.22 µm pore size provides sterile-grade filtration with validated bacterial retention, including Brevundimonas diminuta, ensuring microbial elimination for pharmaceutical applications
Exceptional chemical resistance withstands aggressive organic solvents, including chlorinated compounds, alcohols, ketones, and aromatic hydrocarbons across analytical workflows
Low protein binding characteristics maintain the concentration of therapeutic proteins during sterile filtration, minimizing adsorption losses critical for micro-volume samples
Sterile packaging eliminates initial contamination risks for aseptic micro-volume pharmaceutical processing, supporting GMP compliance requirements in manufacturing facilities

Key Construction Characteristics

1 µL holdup volume maximizes recovery by minimizing sample retention, absolutely critical for preserving expensive analytical standards and rare research compounds
Polypropylene housing provides structural integrity to 87 psi maximum operating pressure with thermal stability to 60°C, ensuring operational confidence for micro-volume sterilization
Dual Luer-Lok and Luer-Slip connections accommodate standard syringes without adapters, streamlining aseptic transfer procedures in pharmaceutical workflows
Integrated polypropylene prefilter with sterile packaging extends membrane lifetime while eliminating contamination risks for precious pharmaceutical samples

Pharmaceutical and analytical laboratories processing micro-volume precious samples require sterilization technology that combines bacterial retention with minimal holdup and aseptic handling. PVDF syringe filters deliver 0.22 µm sterile-grade performance through hydrophobic membrane chemistry and ultra-low holdup design. Optimized for your challenging micro-volume workflows, this filtration solution provides workflow efficiency with proven microbial retention, minimal 1 µL holdup for maximum recovery, and sterile packaging for pharmaceutical development, analytical testing, and research applications demanding both bacterial elimination and sample conservation capabilities with contamination-free processing requirements.
