PTFE Syringe Filters, 0.45um, 33mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF14477

Polytetrafluoroethylene (PTFE) Syringe Filters - SF14477

When you're filtering large volumes of aggressive solvents and need contamination-free handling, these 0.45µm PTFE filters handle everything from strong acids to halogenated organics. The large 33mm diameter with 8.55cm² filtration area processes up to 120ml of sample efficiently while the hydrophobic membrane removes particles from non-aqueous solutions. Pre-sterilized packaging means contamination-free handling, and polypropylene housing withstands pressures up to 87psi. With 100µL holdup volume, you balance sample recovery with high-throughput processing.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane requires alcohol pre-wetting for aqueous solution compatibility
• Universal chemical resistance withstands all organic solvents, acids, and bases without degradation
• Exceptional thermal stability maintains integrity at 60°C continuous operating temperature
• 0.45µm pore size removes particles and suspended solids from large-volume samples
• Pre-sterilized individual packaging ensures contamination-free handling for sensitive applications

Key Construction Characteristics

• Polypropylene housing delivers chemical resistance while withstanding 87psi burst pressure
• Dual Luer-Lok/Luer Slip compatibility accommodates all standard syringe configurations
• Large 33mm diameter with 8.55cm² filtration area for high-volume sample processing
• 100µL holdup volume balances sample recovery with practical handling for large-volume processing

Pre-sterilized packaging means you can start filtering immediately without autoclaving preparation, important when processing large-volume samples. The 59ml/min flow rate through 8.55cm² filtration area provides high throughput for up to 120ml capacity, and you can process samples at temperatures up to 60°C. The 87psi burst pressure handles typical laboratory workflows, and the 7.25psi bubble point confirms consistent 0.45µm pore structure for reproducible particle removal across your clarification runs.
