Polytetrafluoroethylene (PTFE) Syringe Filters - SF14473

When you're filtering aggressive solvents and need contamination-free handling, these 0.45µm PTFE filters combine broad chemical resistance with pre-sterilized packaging. The hydrophobic membrane removes particles from non-aqueous solutions while handling strong acids, bases, and challenging organics like DMF and DMSO. With just 10µL holdup volume in a compact 13mm diameter, you maximize recovery of precious analytical samples. Pre-sterilized packaging means contamination-free handling, and polypropylene housing withstands pressures up to 87psi.

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 conditions
• 0.45µm pore size removes particles and suspended solids from 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 design accommodates all standard syringe configurations
• Compact 13mm diameter with 1.09cm² filtration area for small volume sample processing
• 10µL minimal holdup volume maximizes recovery of precious analytical reagents

Pre-sterilized packaging means you can start filtering immediately without autoclaving preparation, important for contamination-free handling of analytical samples. You recover virtually all of your sample with just 10µL holdup volume - critical when working with expensive reagents or limited-volume specimens. The 11ml/min flow rate through 1.09cm² filtration area provides efficient processing, and the 7.25psi bubble point confirms consistent 0.45µm pore structure for reproducible particle removal across your clarification runs.
