Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18213

Processing analytical samples across diverse organic solvents creates constant challenges when membranes degrade mid-filtration, compromising sample integrity and forcing you to restart preparation workflows. Advanced hydrophobic PVDF membrane technology delivers exceptional chemical resistance across aggressive solvent systems where conventional materials fail. Sterile 0.45µm construction with validated 4.35 psi bubble point and polypropylene housing provides contamination-free clarification for HPLC mobile phases, organic extracts, and chemical formulations. When your analytical workflows require reliable particle removal without bacterial retention claims, this membrane chemistry handles your demanding solvent processing needs.

Key PVDF Membrane Characteristics

Hydrophobic membrane design requires alcohol pre-wetting before aqueous sample processing, ensuring complete membrane activation and consistent flow characteristics throughout your filtration operations
Exceptional chemical stability withstands methanol, chlorinated solvents, and aggressive organic mobile phases that rapidly degrade cellulosic and nylon membrane alternatives
0.45µm pore size removes particulates and protects analytical columns from fouling, providing clarification for chromatography applications without sterile-grade bacterial retention capabilities
High chemical resistance across broad solvent ranges preserves membrane integrity during extended filtration operations with aggressive organic compounds
Broad temperature tolerance up to 80°C accommodates warm sample processing requirements while maintaining membrane integrity throughout demanding laboratory operations

Key Construction Characteristics

Polypropylene housing delivers chemical compatibility with aggressive organic solvents while withstanding elevated temperatures, supporting diverse analytical sample preparation protocols
Double luer lock connection provides secure, leak-proof attachment to syringes and transfer lines, preventing disconnection during manual and automated filtration operations
72.5 psi maximum operating pressure supports both manual syringe filtration and integration with low-pressure pumping systems for higher-throughput sample processing
Sterile gamma-irradiated packaging eliminates bioburden concerns in contamination-sensitive applications, delivering ready-to-use clarification without requiring pre-use sterilization procedures

When your analytical workflows demand clarification across diverse solvent systems from polar buffers to nonpolar organics, membrane chemical resistance determines processing success. PVDF's exceptional solvent stability handles the complete spectrum your laboratory encounters daily, from methanol to chlorinated compounds and aromatic hydrocarbons. Sterile individually-wrapped filters maintain your contamination control protocols while delivering chemical resistance that preserves sample integrity throughout demanding filtration operations. Reliable particle removal protects expensive analytical instrumentation and ensures consistent results across chromatography applications in pharmaceutical and research environments.
