PTFE Syringe Filters, 3.0um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18183

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18183

Featuring hydrophobic PTFE membrane technology with 3.0µm pore size for efficient prefiltration of small-volume samples containing coarse particles and aggregates. Compact 13mm diameter filters deliver impressive 60ml flow rates while preserving precious samples with just 10µl holdup volume. Polypropylene housing construction withstands pressures up to 87psi, ensuring reliable performance with aggressive solvents.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively prefilters organic solvents, acids, and bases without chemical interaction
• Coarse 3.0µm pore size removes large particles, precipitates, and visible contaminants from limited samples
• Outstanding chemical resistance from strong carbon-fluorine bonds maintains stability in harsh solvent systems
• Membrane thickness of 80-140µm optimizes flow characteristics for rapid processing of small volumes
• Autoclavable at 121°C for 30 minutes or gamma sterilizable at 25kGy, ensuring contamination-free operation

Key Construction Characteristics

• Polypropylene housing provides excellent chemical compatibility with organic and inorganic solvents
• Small 13mm diameter with 1.09cm² filtration area, ideal for precious samples and microscale applications
• Ultra-low holdup volume of 10µl maximizes recovery of expensive or irreplaceable analytical samples
• Luer-Lok/Luer Slip dual connection design accommodates various syringe types and volumes

SF18183 filters maximize your small-volume sample recovery with an ultra-low 10µl holdup volume, preserving precious materials while maintaining excellent flow characteristics. Burst pressure rating of 87psi ensures dependable performance across diverse applications while your samples remain stable at operating temperatures up to 60°C. Bubble point verification at 2.9psi using absolute ethyl alcohol confirms consistent pore structure for reproducible prefiltration results.
