Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18307

Laboratories processing heavily particulate-laden organic samples often struggle with rapid membrane fouling. Hydrophobic PVDF syringe filters with a 0.22 µm pore size and a triple-layer prefilter system offer the ultimate solution. The advanced design incorporates glass fiber and polypropylene stages to capture coarse debris before it reaches the final membrane. Progressive filtration significantly extends the life of the filter when processing difficult pharmaceutical solvents. Users must pre-wet the membrane with alcohol for aqueous applications, though it works immediately with organic fluids. Validated bacterial retention ensures sterility even in the most challenging sample matrices.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
• 0.22 µm pore size provides sterile-grade filtration with validated bacterial retention, ensuring microbial elimination for aseptic processing
• Exceptional chemical resistance withstands aggressive organic solvents, including chlorinated compounds and aromatic hydrocarbons
• High structural stability preserves membrane performance under pressure while filtering viscous or particulate-laden fluids
• Sterile packaging eliminates initial contamination risks for sensitive analytical samples to support quality assurance requirements

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 filtration efficiency with a multi-stage device engineered for the dirtiest organic samples. The integrated triple-layer prefilter protects the sterilization membrane to ensure high volume throughput without clogging. You can process aggressive chemical mixtures confident that the hydrophobic PVDF will maintain its structural integrity. Secure Luer-Lok connections prevent hazardous leaks when applying pressure to viscous or sediment-heavy fluids. Rely on this robust solution to maintain aseptic conditions in pharmaceutical manufacturing and environmental testing. Consistent flow rates and extended filter life reduce waste and improve overall laboratory productivity.
