PVDF Syringe Filters, 5.0um, 25mm, Double Luer Lock, PP Housing, Sterile, 100/Pk SKU: SPEC18216

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18216

Featuring 5.0µm hydrophobic polyvinylidene fluoride membrane construction in a sterile 25mm format, this syringe filter delivers gross prefiltration for highly turbid samples where coarse particle removal protects downstream analytical equipment and fine filtration stages. Exceptional chemical resistance handles aggressive organic solvents and chemical formulations. Gamma-irradiated polypropylene housing with double luer lock connection provides contamination-free processing for pharmaceutical manufacturing, chemical analysis, and environmental testing where solvent compatibility and sterile operation both matter.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires alcohol pre-wetting before aqueous sample processing, ensuring proper membrane activation and consistent flow characteristics throughout your filtration operations
• Outstanding chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive chemical reagents that compromise cellulosic and polyamide membrane alternatives in solvent-based applications
• 5.0µm pore size provides gross prefiltration for heavily particulate samples, removing large debris that would rapidly clog finer membranes in multi-stage clarification workflows
• Ultra-low protein binding affinity maintains biomolecule concentrations during coarse prefiltration, preventing adsorptive losses that impact recovery in your sample preparation protocols
• Temperature tolerance to 80°C accommodates warm sample filtration while maintaining chemical compatibility across diverse pharmaceutical and chemical processing conditions

Key Construction Characteristics

• Polypropylene housing offers excellent chemical resistance to organic solvents and aggressive reagents while providing mechanical durability for demanding filtration operations
• Double luer lock connection provides secure, leak-free attachment to syringes and tubing systems, preventing sample loss during manual and automated processing workflows
• 72.5psi maximum operating pressure supports manual syringe filtration and compatibility with low-pressure pumping systems for continuous sample preparation applications
• Sterile gamma-irradiated packaging delivers ready-to-use prefiltration without autoclave requirements, streamlining workflows in pharmaceutical and biotechnology cleanroom environments

When your laboratory processes highly turbid samples where coarse particulates threaten downstream equipment and fine filters, gross prefiltration capacity determines operational success. PVDF's 5.0µm membrane removes large debris your workflows generate. Sterile individually-wrapped units maintain your contamination control standards while delivering the chemical resistance and high-capacity prefiltration that protect expensive analytical systems, extend fine filter life, and ensure reliable sample preparation across challenging pharmaceutical, environmental, and chemical applications.

Hydrophobic

• Viscous Sample Prefiltration — Handle high-viscosity pharmaceutical formulations and polymer solutions where large pores maintain flow without clogging
• Environmental Sample Processing — Prefilter turbid soil extracts and water samples, removing coarse suspended solids before fine filtration or analysis
• Chemical Manufacturing — Process particulate-laden chemical 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 chromatography columns
• Quality Control Prefiltration — Prepare heavily particulate test samples in sterile environments where bioburden control and gross removal both drive success
