PES Syringe Filters, 0.22 um, 13mm, for Ion Chromatography, Nonsterile, 100/Pk SKU: SF18319

Polyethersulfone (PES) Syringe Filters - SF18319

Featuring specialized polyethersulfone membrane technology optimized for ion chromatography applications requiring ultra-low extractables. A 0.22µm absolute pore configuration ensures complete bacterial removal while maintaining critical ionic purity for sensitive analytical measurements. Tisch Scientific engineers combine hydrophilic PES membranes with polypropylene housing construction to eliminate ionic contamination in trace-level chromatographic analysis.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane provides immediate wetting without surfactants that interfere with IC analysis
• Ultra-low extractables profile prevents ionic contamination in sensitive chromatographic applications
• Broad chemical resistance tolerates mobile phase buffers and pH extremes from 1-14
• 0.22µm absolute pore rating delivers complete bacterial and microorganism removal
• Autoclavable construction enables sterilization at 121°C for 30 minutes when required

Key Construction Characteristics

• Polypropylene housing eliminates metal ion leaching common with standard filter assemblies
• Dual Luer-Lok/Luer Slip compatibility ensures secure connection with all syringe types
• Compact 13mm diameter design optimized for small volume ion chromatography samples
• 10µl minimal holdup volume preserves precious samples and standards for IC analysis

SF18319 syringe filters maintain consistent 5.5ml/min flow rates through a precision 1.09cm² filtration area, providing controlled filtration speeds essential for your ion chromatography sample preparation. Specialized low-extractables construction eliminates ionic background contamination that compromises chromatographic baselines, ensuring accurate quantitation at ppb levels. Autoclave compatibility at 121°C transforms nonsterile units into validated sterile filters, supporting your most demanding analytical protocols requiring both bacterial removal and ionic purity.
