Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18218

Laboratories processing aggressive organic solvents often require cost-effective filtration solutions that withstand harsh chemicals. Hydrophobic PVDF syringe filters with a 0.45 µm pore size provide robust clarification without the expense of pre-sterilized units. The membrane requires alcohol pre-wetting for aqueous fluids but processes organic mixtures immediately. A durable 20mm ABS housing features threaded double Luer Lock connections to ensure secure attachment under pressure. Users can autoclave the nonsterile units to achieve sterility when needed for critical applications. The flexible design efficiently handles medium-volume samples, protecting analytical instruments from particulate damage in demanding workflows.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
• 0.45 µm pore size delivers reliable particle removal and clarification for heavily loaded samples without bacterial retention
• Exceptional chemical resistance maintains compatibility with aggressive organic solvents, including chlorinated compounds and aromatic hydrocarbons
• 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 autoclave sterilization cycles without degradation

Key Construction Characteristics

• Threaded double Luer Lock connections secure both inlet and outlet ports to eliminate disconnection risks
• Durable ABS housing withstands operating pressures to 72.5 psi providing mechanical strength for demanding protocols
• Nonsterile construction allows for autoclave sterilization before first use providing economical sterile filtration capability
• 20mm diameter platform supports medium-volume clarification balancing processing capacity with material economy

Strengthen your analytical sample preparation with a filtration device engineered for flexibility and economy. You can clarify organic solvents and mobile phases reliably without risking membrane degradation. The 0.45 µm pore size effectively removes particulates to extend the life of chromatography columns. Threaded double Luer Lock connections prevent hazardous leaks when filtering toxic fluids. Rely on the autoclavable design to provide sterility only when your specific protocol demands it. The hydrophobic chemistry supports specialized applications like air venting and gas filtration. Consistent particle retention ensures that your data remains accurate across pharmaceutical and environmental testing.
