PVDF Syringe Filters w/ 3 Pre-Filters, 0.22 um, 25mm, Sterile, 100/Pk SKU: SF18308

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18308

Laboratories handling particle-laden organic solvents often struggle with premature membrane fouling. Hydrophobic PVDF syringe filters with a 0.22 µm pore size offer a robust solution for these difficult samples. The integrated triple-layer prefilter system captures coarse debris progressively to extend the life of the final membrane. A combination of glass fiber and polypropylene stages ensures high throughput even with viscous fluids. Operators must pre-wet the unit with alcohol for aqueous applications, though it works immediately with organic mixtures. Sterile packaging guarantees contamination-free processing for critical pharmaceutical workflows requiring absolute bacterial retention.

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 withstands aggressive organic solvents, including chlorinated compounds and aromatic hydrocarbons
• High structural stability preserves membrane performance under pressure while filtering viscous or particulate-laden fluids
• Sterile packaging eliminates initial contamination risks for sensitive analytical samples to support quality assurance requirements

Key Construction Characteristics

• Triple-layer prefilter system captures coarse particulates progressively to dramatically extend membrane lifetime in challenging samples
• 100 µL holdup volume minimizes loss of valuable pharmaceutical compounds and biological materials optimizing yield
• Polypropylene housing delivers structural integrity to 87 psi maximum operating pressure with thermal stability to 60°C
• Dual Luer-Lok and Luer-Slip connections accommodate standard syringes without adapters streamlining aseptic transfer procedures

Maximize your filtration efficiency with a device engineered for the most challenging chemical matrices. You can process dirty organic solvents reliably without sacrificing sterility or flow speed. The validated 0.22 µm pore size ensures the complete removal of bacteria during aseptic transfers. Secure Luer-Lok connections prevent hazardous leaks when applying pressure to viscous or sediment-heavy fluids. Rely on gamma-sterilized packaging to maintain aseptic conditions in your pharmaceutical manufacturing environment. The durable housing and multi-stage filtration design reduce waste by preventing rapid clogging during routine sample preparation.
