PVDF Syringe Filters, 0.22 um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18217

Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18217 Laboratories seeking flexible sterilization options often find pre-sterilized filters add unnecessary expense. Nonsterile 0.22 µm PVDF syringe filters offer a cost-effective alternative for routine sample preparation. The hydrophobic membrane requires alcohol pre-wetting for aqueous samples but handles organic solvents immediately. A compact 20mm ABS housing features a threaded double Luer Lock for secure connections. Users can autoclave the units before use to achieve sterile-grade performance. The design supports HPLC mobile phases and biological samples efficiently. It provides robust bacterial retention and chemical resistance for critical analytical workflows.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
• 0.22 µm pore size provides sterile-grade filtration with validated bacterial retention, ensuring microbial elimination after autoclave sterilization
• 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

Optimize your analytical workflows with a filtration solution designed for flexibility and economy. You can sterilize the filters via autoclave to meet specific sterility requirements. The 0.22 µm pore size ensures the complete removal of bacteria from mobile phases. Threaded double Luer Lock connections prevent disconnection during high-pressure processing. Hydrophobic PVDF chemistry offers superior resistance to aggressive organic solvents. Rely on the durable ABS housing for consistent performance in daily laboratory tasks. The configuration delivers reliable results for HPLC and pharmaceutical applications without the cost of pre-sterilized units.
