PVDF Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Sterile, 100/Pk SKU: SF18310

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18310

Laboratories processing heavily particulate-laden organic samples often struggle with premature membrane fouling. Hydrophobic PVDF syringe filters with a 0.45 µm pore size and triple-layer prefiltration provide a robust solution. The advanced design combines glass fiber and polypropylene stages to capture coarse debris progressively. Progressive filtration significantly extends the operational life of the final clarification membrane. Users must pre-wet the unit with alcohol for aqueous fluids, though it processes organic solvents immediately. The 25mm housing supports high flow rates for efficient batch processing. Validated sterile packaging ensures contamination-free handling during critical clarification steps.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples but allows direct filtration of organic solvents
• 0.45 µm pore size delivers reliable particle removal and clarification for heavily loaded samples without bacterial retention
• Exceptional chemical resistance maintains compatibility with aggressive organic solvents including chlorinated compounds and aromatic hydrocarbons
• High flow rates enable the rapid processing of viscous or particulate-laden organic samples to improve laboratory efficiency
• Broad solvent resistance ensures structural integrity across alcohols, ketones, and acids for consistent performance in challenging applications

Key Construction Characteristics

• Triple-layer prefilter system captures coarse particulates progressively to dramatically extend membrane lifetime in challenging samples
• 100 µL holdup volume minimizes loss of valuable pharmaceutical compounds and biological materials optimizing yield
• Polypropylene housing delivers structural integrity to 87 psi maximum operating pressure with thermal stability to 60°C
• Dual Luer-Lok and Luer-Slip connections accommodate standard syringes without adapters streamlining aseptic transfer procedures

Maximize your laboratory productivity with a filtration solution engineered for the most difficult solvent matrices. You can process viscous or dirty organic fluids reliably without frequent filter changes. The integrated triple-layer prefilter protects the 0.45 µm membrane from premature clogging by larger particles. Secure Luer-Lok connections prevent hazardous leakage when applying pressure to resistant samples. The hydrophobic chemistry offers exceptional durability against aggressive acids, alcohols, and chlorinated solvents. Rely on this robust design to maintain high throughput in pharmaceutical development and chemical analysis. Consistent particle removal protects sensitive chromatography columns and extends the life of analytical instrumentation.
