PTFE Syringe Filters, 1.0um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18240

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18240

Featuring hydrophobic PTFE membrane technology with 1.0µm pore size in pre-sterilized packaging for reliable particle removal and sample clarification in aggressive solvent systems. Standard 25mm diameter filters deliver efficient 70ml flow rates while maintaining consistent retention of fine particulates and suspended matter. Polypropylene housing construction ensures robust performance at pressures up to 87psi across diverse sterile applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively filters organic solvents, acids, and bases without chemical interaction
• Precision 1.0µm pore size removes fine particles, suspended solids, and microbial contaminants from samples
• Pre-sterilized by gamma irradiation ensures contamination-free filtration for critical aseptic applications
• Exceptional chemical resistance from strong carbon-fluorine bonds maintains stability in caustic environments
• Membrane thickness of 80-140µm balances optimal flow rates with superior particle retention capabilities

Key Construction Characteristics

• Polypropylene housing provides broad chemical compatibility with aggressive solvents and reagents
• Standard 25mm diameter offers 4.08cm² filtration area for efficient processing of routine sample volumes
• Holdup volume of 100µl minimizes sample loss while maintaining practical handling characteristics
• Luer-Lok/Luer Slip dual connection system ensures secure attachment to all standard syringe types

SF18240 filters optimize your sterile sample preparation with a 70ml flow rate that balances throughput with exceptional particle retention. Pre-sterilized packaging eliminates preparation steps while your samples maintain complete sterility at operating temperatures up to 60°C. Bubble point verification at 4.35psi using absolute ethyl alcohol confirms consistent membrane pore structure for reproducible sterile filtration results.
