Thumbnail Filmstrip of PTFE Syringe Filters, 1.0um, 30mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Polytetrafluoroethylene (PTFE) Syringe Filters - SF18324
Featuring hydrophobic PTFE membrane technology with 1.0µm pore size for reliable particle removal and sample clarification in aggressive solvent systems. Large 30mm diameter filters deliver efficient 85ml 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 interaction
- Precision 1.0µm pore size removes fine particles, suspended solids, and microbial contaminants from solutions
- 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
- Autoclavable at 121°C for 30 minutes or gamma sterilizable at 25kGy for contamination-free processing
Key Construction Characteristics
- Polypropylene housing provides broad chemical compatibility with aggressive solvents and reagents
- Large 30mm diameter offers 4.9cm² filtration area for efficient processing of high-volume samples
- Holdup volume of 100µl minimizes sample loss while maintaining practical handling characteristics
- Luer-Lok/Luer Slip dual connection system ensures secure attachment to various syringe sizes
SF18324 filters optimize your sample preparation workflow with an 85ml flow rate that balances throughput with exceptional particle retention. Large 30mm diameter configuration enables rapid processing while your samples maintain integrity at operating temperatures up to 60°C. Bubble point verification at 4.35psi using absolute ethyl alcohol confirms consistent membrane pore structure for reproducible filtration results across the 120ml volume throughput capacity.
