PTFE Syringe Filters, 3.0um, 33mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF17044

Polytetrafluoroethylene (PTFE) Syringe Filters - SF17044

Featuring hydrophobic PTFE membrane technology with 3.0µm pore size for efficient prefiltration and coarse particle removal from aggressive chemical systems. High-capacity 33mm diameter filters deliver exceptional 200ml flow rates while protecting downstream fine filters from premature clogging. Polypropylene housing construction withstands pressures up to 87psi, ensuring reliable performance across demanding laboratory applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively prefilters organic solvents, acids, and bases without chemical degradation
• Coarse 3.0µm pore size removes large particles, aggregates, and visible contaminants from bulk solutions
• Superior chemical resistance from strong carbon-fluorine bonds maintains membrane integrity in harsh solvents
• Membrane thickness of 80-140µm provides an optimal balance between flow rate and particle retention efficiency
• Autoclavable at 121°C for 30 minutes or gamma sterilizable at 25kGy for contamination-free processing

Key Construction Characteristics

• Polypropylene housing ensures broad chemical compatibility with organic and inorganic solvent systems
• Large 33mm diameter provides 4.9cm² filtration area for rapid processing of high-volume samples
• Holdup volume of 100µl minimizes sample loss while maintaining practical handling for routine applications
• Luer-Lok/Luer Slip dual connection design accommodates various syringe sizes and automated systems

SF17044 filters maximize your prefiltration efficiency with an impressive 200ml flow rate, significantly reducing processing time for large-volume samples. Burst pressure rating of 87psi ensures dependable performance under standard laboratory conditions while your samples remain stable at operating temperatures up to 60°C. Bubble point specification of 2.9psi using absolute ethyl alcohol confirms consistent pore structure for reproducible coarse filtration results.
