PVDF Syringe Filters, 0.45um, 20mm, Threaded Double Luer Lock, ABS Housing, Sterile, 100/Pk SKU: SPEC18223

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18223

Precision 0.45µm hydrophobic PVDF membrane construction with validated 4.35psi bubble point delivers sterile gamma-irradiated clarification in compact 20mm ABS housing optimized for small-volume organic solvent processing. Particulate removal protects analytical equipment from fouling without bacterial retention claims appropriate for clarification applications. Ready-to-use design with threaded double luer lock connection and 72.5psi operating pressure supports HPLC mobile phase preparation, chemical formulations, and environmental samples where space-efficient clarification combines with contamination-free processing and exceptional solvent compatibility.

Key PVDF Membrane Characteristics

• Hydrophobic surface requires alcohol pre-wetting before aqueous processing, activating the membrane for proper flow and preventing channeling that compromises filtration efficiency
• Outstanding chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly degrade cellulosic and polyamide membrane alternatives
• 0.45µm pore size removes particulates and protects analytical systems from fouling, providing clarification for organic solvents and chemical samples without bacterial retention
• Ultra-low protein binding characteristics preserve biomolecule concentrations throughout clarification, preventing adsorptive losses that compromise recovery in your sample preparation workflows
• Temperature tolerance to 80°C supports elevated-temperature sample processing while maintaining chemical compatibility across diverse pharmaceutical and chemical laboratory applications

Key Construction Characteristics

• ABS housing provides chemical resistance to common organic solvents while delivering mechanical strength for manual filtration operations in routine sample preparation
• Threaded double luer lock connection creates secure, leak-proof attachment to syringes and transfer lines, preventing disconnection during processing workflows
• 72.5psi maximum operating pressure accommodates manual syringe filtration and integration with low-pressure pumping systems for automated sample preparation
• Sterile gamma-irradiated packaging delivers contamination-free clarification without requiring pre-use sterilization, streamlining workflows in pharmaceutical and biotechnology cleanroom environments

Built to support your compact analytical workflows where space-constrained processing requires sterile clarification with broad organic solvent compatibility. PVDF's exceptional chemical stability handles the diverse solvent systems your laboratory encounters. Sterile individually-wrapped units maintain your contamination control standards while delivering the solvent resistance and particulate removal that protect analytical instrumentation, preserve sample integrity, and ensure reliable results across demanding HPLC, chemical analysis, and pharmaceutical applications where clarification capacity drives analytical success.
