Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18222

Laboratories handling small-volume organic solvent samples often struggle to find compact sterile filtration solutions. Hydrophobic PVDF syringe filters with a 0.22 µm pore size provide a robust barrier against bacteria in chemical fluids. The membrane requires alcohol pre-wetting for aqueous fluids but processes organic mixtures immediately. A sterile 20mm ABS housing features threaded double Luer Lock connections for secure attachment. The secure design prevents leaks when processing hazardous fluids under pressure. Validated gamma-sterilization ensures contamination-free handling for critical applications. Researchers rely on this compact design for chemically aggressive environments.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
• 0.22 µm pore size provides sterile-grade filtration with validated bacterial retention, ensuring microbial elimination for aseptic processing
• 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 elevated-temperature solvent applications

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
• Sterile gamma-irradiated packaging provides contamination-free filtration without requiring pre-use sterilization
• 20mm diameter platform supports medium-volume clarification balancing processing capacity with material economy

Optimize your sterile workflows with a filtration device built for aggressive chemical environments. You can sterilize organic solvents and mobile phases reliably without risking membrane failure. The 0.22 µm pore size ensures absolute retention of bacteria to maintain aseptic conditions. Threaded double Luer Lock connections prevent hazardous leaks when filtering toxic fluids under pressure. Rely on gamma-sterilized packaging to support strict quality control protocols in pharmaceutical manufacturing. Consistent performance ensures that your analytical instruments remain protected from particulate damage. Choose this durable solution for your most demanding sterile filtration tasks.
