Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18208

Analytical chemistry and pharmaceutical laboratories demand robust clarification solutions for aggressive organic solvent-based samples. Hydrophobic 0.45 µm PVDF syringe filters provide exceptional chemical resistance where hydrophilic membranes often degrade. The membrane requires alcohol pre-wetting for aqueous fluids but processes organic solvents immediately. A robust polypropylene housing features a double Luer Lock design to secure connections at both ends. Validated structural integrity withstands burst pressures up to 116 psi and temperatures reaching 80°C. The 25mm configuration ensures reliable performance for medium-volume samples ranging from 10 to 100 mL.

Key PVDF Membrane Characteristics

• Hydrophobic surface requires pre-wetting with alcohol before processing aqueous samples, but enables specialized air venting capabilities
• Exceptional chemical compatibility resists degradation from alcohols, ketones, and esters that destroy standard membrane materials
• Naturally hydrophobic surface enables gas venting applications by efficiently displacing air from liquid handling systems
• Extended temperature stability to 80°C accommodates warm sample filtration and elevated-temperature solvent applications
• 0.45 µm pore size removes particulates and cellular debris from organic samples, providing clarification without bacterial retention

Key Construction Characteristics

• Robust polypropylene housing withstands operating pressures to 72.5 psi providing mechanical strength for demanding protocols
• Validated 116 psi burst pressure ensures structural integrity during high-pressure filtration operations preventing catastrophic failure
• Double Luer Lock connections secure both inlet and outlet ports to eliminate disconnection risks
• 25mm diameter platform supports medium-volume clarification for samples up to 100 mL balancing capacity with economy

Built to support your chemical analysis workflows, this filtration solution delivers the resistance needed for aggressive solvents. The 25mm platform processes medium-volume samples consistently while maintaining high flow rates. You can rely on the 116 psi burst pressure rating to prevent failures during high-stress operations. Double Luer Lock connections eliminate disconnection risks when handling hazardous chemicals under pressure. The hydrophobic nature makes these units ideal for air venting and gas filtration applications. Consistent clarification ensures that your analytical instruments remain protected from particulate damage.
