PVDF Syringe Filters, 0.45um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18218

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18218

Pharmaceutical and analytical laboratories require economical clarification for organic solvent samples where user sterilization provides cost savings over pre-sterilized alternatives. Advanced 0.45µm PVDF membrane technology delivers particulate removal with exceptional chemical resistance and autoclave compatibility. Nonsterile hydrophobic construction in compact 20mm ABS housing with threaded double luer lock provides clarification capability for HPLC mobile phases, chemical formulations, and environmental samples after user sterilization where needed.

Key PVDF Membrane Characteristics

• Hydrophobic surface requires initial alcohol wetting before aqueous sample processing, ensuring complete membrane activation and preventing channeling during filtration operations
• Outstanding chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly degrade cellulosic and nylon membrane alternatives
• 0.45µm pore size removes particulates and protects analytical equipment 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 both elevated-temperature sample processing and autoclave sterilization cycles without membrane degradation or structural compromise

Key Construction Characteristics

• ABS housing delivers chemical resistance to common organic solvents while providing mechanical strength for routine manual filtration operations in analytical workflows
• Threaded double luer lock connection creates secure, leak-proof attachment to syringes and transfer lines, preventing disconnection during processing operations
• 72.5psi maximum operating pressure supports manual syringe filtration and integration with low-pressure pumping systems for automated sample preparation
• Nonsterile construction with autoclave capability provides economical clarification with user sterilization flexibility, reducing costs compared to pre-sterilized alternatives

Built to support your analytical workflows where organic solvent clarification requires chemical resistance without the added cost of pre-sterilized filters. PVDF's exceptional solvent stability combined with autoclave compatibility delivers economical processing flexibility. Nonsterile units become sterile-ready after autoclaving, providing the chemical resistance and particulate removal that protect analytical instrumentation, maintain sample integrity, and ensure reliable results across demanding HPLC, chemical analysis, and pharmaceutical applications where clarification matters.
