PVDF Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF14457

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF14457

Precision PVDF membrane construction with 0.45 µm pore rating, 25mm diameter, and 4.08 cm² filtration area provides efficient clarification of organic solvents and non-aqueous samples for analytical chemistry and pharmaceutical applications requiring chemical-resistant filtration without sterile-grade particle retention. This configuration delivers high-throughput processing capabilities. Subsequently, the integrated polypropylene prefilter extends operational life by capturing larger particles before they reach the primary membrane, while the hydrophobic membrane structure ensures optimal performance with non-polar solvents and requires alcohol pre-wetting for aqueous sample processing.

Key PVDF Membrane Characteristics

Hydrophobic nature optimized for organic solvent processing, requiring pre-wetting with methanol or ethanol before transitioning to water-based samples
Broad chemical compatibility resists degradation from aggressive solvents, acids, and bases across pH ranges from 1-14 without membrane swelling or dissolution
0.45 µm pore rating removes particles and clarifies solutions for analytical procedures where bacterial removal is not required
Low protein affinity maintains sample composition by minimizing biomolecule adsorption, essential for accurate protein quantification and enzymatic activity measurements
Robust mechanical properties support pressures up to 87 psi, enabling rapid filtration of viscous samples and high-volume processing requirements

Key Construction Characteristics

100 µL holdup volume minimizes loss of expensive analytical samples and reagents by reducing retention within the filter assembly
Polypropylene housing maintains structural integrity at operating temperatures up to 60°C and withstands both autoclave and gamma sterilization procedures
Luer-Lok and Luer-Slip dual connections interface seamlessly with standard laboratory syringes without requiring specialty adapters or modified equipment
4.08 cm² filtration area with polypropylene prefilter configuration maximizes throughput capacity for medium-volume sample processing applications

Analytical and pharmaceutical laboratories processing medium-volume organic samples require clarification technology that combines chemical resistance with efficient particle removal. PVDF syringe filters deliver 0.45 µm clarification performance with broad solvent compatibility and low protein binding. Optimized for your challenging analytical workflows, this membrane technology provides processing confidence via validated chemical resistance and high-throughput capacity for routine sample preparation and quality control applications requiring reliable clarification without bacterial retention specifications.
