PVDF Syringe Filters, 1.0um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18219

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18219

Precision 1.0µm hydrophobic PVDF membrane construction with validated 1.45psi bubble point delivers nonsterile coarse prefiltration in compact 20mm ABS housing optimized for small to medium-volume sample processing. Coarse particle removal protects downstream fine filters and analytical systems from premature fouling in multi-stage workflows. Autoclavable construction with threaded double luer lock connection and 72.5psi operating pressure provides user sterilization flexibility for biological samples, chemical formulations, and environmental testing where cost-effective prefiltration capacity drives operational efficiency.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires alcohol pre-wetting before aqueous processing, activating the membrane for consistent flow and preventing air-lock conditions throughout filtration
• Broad chemical compatibility resists degradation from organic solvents, acids, and aggressive reagents, maintaining membrane performance throughout challenging pharmaceutical and chemical applications
• 1.0µm pore size removes coarse particulates and extends downstream filter life, providing high-capacity prefiltration for turbid samples requiring multi-stage clarification
• Ultra-low protein binding preserves biomolecule concentrations during coarse prefiltration steps, preventing adsorptive losses that compromise recovery in protein purification workflows
• Temperature stability to 80°C accommodates both warm sample processing and autoclave sterilization cycles, delivering operational flexibility for diverse laboratory applications

Key Construction Characteristics

• ABS housing provides chemical resistance to common organic solvents while delivering mechanical durability for manual filtration operations in routine sample preparation
• Threaded double luer lock connection ensures secure, leak-proof attachment to syringes and tubing, preventing sample loss during manual and automated workflows
• 72.5psi maximum operating pressure supports manual syringe filtration and compatibility with low-pressure pumping systems for continuous processing applications
• Nonsterile construction with autoclave capability allows user sterilization before first use, providing economical prefiltration while maintaining sterilization flexibility

When your laboratory processes turbid samples where coarse particulates threaten downstream filters and analytical equipment, prefiltration capacity determines operational costs. PVDF's 1.0µm membrane combined with autoclave compatibility delivers economical protection. Nonsterile units become sterile-ready after autoclaving, providing the chemical resistance and coarse particle removal that extend fine filter life, reduce replacement frequency, and ensure consistent sample preparation across demanding pharmaceutical, biotechnology, and environmental applications where prefiltration economics matter.

Hydrophobic

• Biological Sample Prefiltration — Remove coarse debris from lysates and homogenates before fine filtration, protecting downstream membranes
• Cell Culture Media Processing — Prefilter turbid culture media and fermentation broths where high particulate loads require robust clarification
• Chemical Manufacturing — Process particulate-laden intermediates where solvent resistance maintains membrane integrity throughout production
• Environmental Sample Preparation — Prefilter soil extracts and water samples, removing suspended solids before fine filtration or analysis
• Pharmaceutical Formulation — Clarify viscous drug formulations where coarse removal protects final filtration stages from premature fouling
• Quality Control Prefiltration — Prepare turbid samples where autoclave sterilization provides contamination control at lower cost than pre-sterilized units
