PTFE Syringe Filters, 3.0um, 13mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18276

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18276

Featuring hydrophobic PTFE membrane technology with 3.0µm pore size in pre-sterilized packaging for aseptic prefiltration of small-volume samples. 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 in sterile applications.

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
• Pre-sterilized by gamma irradiation ensures contamination-free filtration for critical aseptic applications
• 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

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

SF18276 filters maximize your sterile small-volume sample recovery with an ultra-low 10µl holdup volume, preserving precious materials while maintaining complete sterility. Burst pressure rating of 87psi ensures dependable performance across diverse applications while your samples remain protected at operating temperatures up to 60°C. Pre-sterilized packaging eliminates preparation steps for immediate use in aseptic environments.
