Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18207

Aggressive organic solvents and challenging chemical samples degrade standard hydrophilic membranes, forcing you to compromise between chemical compatibility and bacterial retention capability in critical filtration applications where both properties matter. Hydrophobic 0.22µm PVDF membrane technology addresses this limitation with exceptional solvent resistance. Advanced membrane construction with validated 7.25psi bubble point, 116psi burst pressure, and double Luer Lock connections provides the chemical durability your workflows demand when processing solvent-based samples.

Key PVDF Membrane Characteristics

• Hydrophobic 0.22µm PVDF membrane requires alcohol pre-wetting before aqueous sample processing but enables specialized air venting applications and aggressive solvent filtration unavailable with hydrophilic materials
• Exceptional chemical resistance maintains membrane integrity across alcohols, ketones, esters, halogenated hydrocarbons, and aggressive organic solvents that destroy temperature-sensitive or chemically incompatible membrane materials
• Low protein binding characteristics preserve biomolecule concentrations during filtration, essential when your analytical protocols depend on maintaining accurate sample composition throughout preparation workflows
• Extended temperature stability to 80°C accommodates warm sample processing and high-temperature solvent applications that exceed the thermal limits of standard membrane chemistries
• Fine 0.22µm pore size removes bacteria-sized particles from organic and pre-wetted aqueous samples, providing particulate control approaching sterile-grade filtration in chemically challenging matrices

Key Construction Characteristics

• Durable polypropylene housing withstands operating pressures to 72.5psi and temperatures to 80°C, delivering mechanical robustness when your processing conditions stress standard equipment
• Validated 116psi burst pressure ensures structural integrity under high-pressure filtration operations, preventing membrane failure when protocols demand reliable construction across diverse sample types
• Double Luer Lock connections provide secure attachment on both inlet and outlet ports, eliminating accidental disconnection risks when handling aggressive solvents under pressure
• 25mm diameter platform supports medium-volume filtration for 10-100ml samples, balancing processing capacity with material economy in routine laboratory operations

When your laboratory processes chemically challenging samples where hydrophilic membranes degrade, hydrophobic PVDF construction delivers the solvent resistance you need without sacrificing particulate removal. The 25mm platform with 116psi burst pressure and 80°C temperature stability handles medium-volume samples consistently. Combined with fine particulate removal capability and double Luer Lock security, this configuration ensures your laboratory achieves reliable performance across organic solvent filtration, air venting applications, and chemically demanding sample preparation where membrane compatibility determines processing success.
