PVDF Syringe Filters, 5.0um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18221

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18221

Highly turbid samples with heavy particulate loads create processing bottlenecks when fine filters clog rapidly, forcing you to interrupt workflows for frequent filter changes and driving up operational costs. Nonsterile 5.0µm PVDF membrane technology delivers economical gross prefiltration with exceptional chemical resistance and autoclave compatibility. Compact 20mm ABS housing with threaded double luer lock connection provides cost-effective coarse particle removal for viscous formulations, environmental samples, and chemical processing where user sterilization flexibility reduces expenses.

Key PVDF Membrane Characteristics

• Hydrophobic surface requires alcohol pre-wetting before aqueous processing, activating the membrane for consistent flow and preventing air-lock conditions during filtration
• Outstanding chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly compromise cellulosic and nylon membrane alternatives
• 5.0µm pore size provides gross prefiltration for heavily particulate samples, removing large debris that would rapidly clog finer membranes in your multi-stage workflows
• Ultra-low protein binding affinity maintains biomolecule concentrations during coarse prefiltration, preventing adsorptive losses that compromise recovery in biological sample preparation
• Temperature tolerance to 80°C supports elevated-temperature sample processing and autoclave sterilization cycles, delivering operational flexibility for diverse laboratory applications

Key Construction Characteristics

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

Engineered to overcome your prefiltration challenges where heavily turbid samples with high particulate loads compromise downstream filter performance and drive operational expenses. PVDF's gross filtration capacity combined with autoclave compatibility delivers economical equipment 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, environmental, and chemical applications where prefiltration economics determine purchasing decisions.

Hydrophobic

• Viscous Sample Prefiltration — Handle high-viscosity pharmaceutical formulations where large pores maintain flow rates without premature clogging
• Environmental Sample Processing — Prefilter turbid soil extracts and water samples, removing coarse suspended solids before fine filtration
• Chemical Manufacturing — Process particulate-laden intermediates where solvent resistance maintains membrane performance throughout production workflows
• Biological Sample Clarification — Remove large cellular debris from lysates and homogenates before fine filtration, protecting downstream membranes
• Equipment Protection — Guard sensitive analytical instrumentation from coarse particulates that damage pumps, detectors, and columns
• Quality Control Prefiltration — Prepare heavily particulate samples where autoclave sterilization provides contamination control at lower cost
