PTFE Syringe Filters, 1.0um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF15172

Polytetrafluoroethylene (PTFE) Syringe Filters - SF15172

Featuring hydrophobic PTFE membrane technology with 1.0µm pore size 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 laboratory applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively filters organic solvents, acids, and bases without chemical degradation
• Precision 1.0µm pore size removes fine particles, suspended solids, and microbial contaminants from samples
• Exceptional chemical resistance from strong carbon-fluorine bonds maintains integrity in caustic environments
• Membrane thickness of 80-140µm balances optimal flow rates with superior particle retention capabilities
• Autoclavable at 121°C for 30 minutes or gamma sterilizable at 25kGy for contamination-free processing

Key Construction Characteristics

• Polypropylene housing material provides broad chemical compatibility with aggressive solvents and reagents
• Standard 25mm diameter offers 4.08cm² filtration area for efficient processing of routine sample volumes
• Low holdup volume of 100µl minimizes sample loss, preserving valuable analytes and limited samples
• Luer-Lok/Luer Slip dual connection system ensures secure attachment to all standard syringe types

SF15172 filters optimize your sample preparation with a 70ml flow rate that balances throughput with exceptional particle retention. Burst pressure rating of 87psi ensures reliable performance under standard laboratory conditions while your samples maintain integrity at operating temperatures up to 60°C. Bubble point verification at 4.35psi using absolute ethyl alcohol confirms a consistent membrane pore structure for reproducible filtration results.
