Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18226

Analytical laboratories processing micro-volume precious samples face dual challenges of sample loss from holdup and contamination risks during handling, requiring clarification technology that maximizes recovery through minimal retention while delivering contamination-free processing across organic solvent systems and aggressive chemical environments without bacterial retention specifications. Polyvinylidene fluoride membrane technology with 0.45 µm pore size and ultra-low 1 µL holdup addresses this challenge through compact 0.125 cm² filtration area specifically engineered for volumes less than 1 ml while maintaining sterile packaging for aseptic handling. Additionally, the hydrophobic surface chemistry provides exceptional chemical resistance while enabling efficient particulate removal for expensive analytical standards, rare pharmaceutical compounds, and limited-availability research materials requiring maximum recovery with contamination-free clarification in chromatography preparation and quality control workflows.

Key PVDF Membrane Characteristics

Hydrophobic surface requires pre-wetting with alcohols or compatible organic solvents before aqueous processing, optimizing performance for micro-volume organic sample clarification
0.45 µm pore size removes particulates from analytical samples for chromatography workflows, protecting downstream instrumentation without providing sterile-grade filtration
Exceptional chemical resistance, stable operation with aggressive organic solvents, including chlorinated compounds, ketones, esters, and aromatic hydrocarbons across workflows
Low protein binding characteristics minimize adsorption during sample preparation, preserving biomolecule concentration in pharmaceutical analytical applications
Sterile packaging eliminates initial contamination risks for sensitive analytical samples, supporting quality assurance requirements in pharmaceutical laboratories

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, ensuring operational confidence for micro-volume clarification applications
Dual Luer-Lok and Luer-Slip connections accommodate standard syringes without adapters, streamlining workflow integration in pharmaceutical testing environments
Integrated polypropylene prefilter with sterile packaging extends membrane lifetime while eliminating contamination risks for precious pharmaceutical samples
