PVDF Syringe Filters, 3.0um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18220

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18220

Featuring a 3.0µm hydrophobic polyvinylidene fluoride membrane construction in a nonsterile, compact 20mm ABS housing, this syringe filter delivers economical coarse prefiltration for turbid samples that require chemical resistance, with user-sterilization flexibility. Gross particle removal protects downstream fine filters and analytical equipment from premature clogging. Autoclavable design with threaded double luer lock connection and 72.5psi operating pressure supports pharmaceutical manufacturing, environmental testing, and chemical analysis where cost-effective prefiltration capacity combines with broad solvent compatibility.

Key PVDF Membrane Characteristics

• Hydrophobic membrane requires alcohol pre-wetting before aqueous sample processing, activating the surface for proper flow and preventing channeling that compromises filtration efficiency
• Exceptional chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly degrade cellulosic and polyamide membrane alternatives
• 3.0µm pore size provides coarse prefiltration for heavily particulate samples, removing large debris that would rapidly clog finer membranes in multi-stage workflows
• Ultra-low protein binding maintains biomolecule concentrations during coarse prefiltration, preventing adsorptive losses that impact recovery in your biological sample preparation protocols
• Temperature tolerance to 80°C supports warm sample processing and autoclave sterilization cycles, delivering operational flexibility for diverse laboratory filtration applications

Key Construction Characteristics

• ABS housing offers chemical resistance to common organic solvents while providing mechanical strength for manual filtration operations in routine sample preparation
• Threaded double luer lock connection ensures 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
• Nonsterile construction with autoclave capability provides economical prefiltration with user sterilization flexibility, reducing costs compared to pre-sterilized alternatives

When your laboratory processes highly turbid samples where coarse particulates threaten downstream equipment, prefiltration economics drive purchasing decisions. PVDF's chemical versatility combined with autoclave compatibility delivers cost-effective protection. Nonsterile units become sterile-ready after autoclaving, providing the solvent 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 capacity matters.

Hydrophobic

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