Thumbnail Filmstrip of PES Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, PFAS-Free, 100/Pk Images
Featuring a naturally hydrophilic polyethersulfone (PES) membrane with a 0.22um pore size, these syringe filters deliver fast, efficient filtration of aqueous and organic solutions while protecting sensitive analytical samples. The 25mm membrane diameter balances throughput with manageable hold-up volume, and the PFAS-free construction makes these filters well suited for PFAS testing and trace analysis where background contamination must be avoided. A transparent polypropylene housing with Luer-Lok inlet and Luer Slip outlet connections provides broad chemical compatibility and a secure syringe fit, and the filters ship nonsterile in packs of 100.
Key PES Membrane Characteristics
- Naturally hydrophilic polyethersulfone structure wets out readily without pretreatment for consistent flow.
- Very low protein and drug binding maximizes recovery of critical analytes and sample volume.
- 0.22um pore size provides sterilizing-grade retention for clarification and microbiological sample preparation.
- Wide chemical compatibility range handles both aqueous and organic solutions.
- PFAS-free membrane and construction minimize background interference in trace and PFAS analysis.
Key Construction Characteristics
- Transparent polypropylene housing for broad chemical resistance and visual sample monitoring.
- Luer-Lok/Luer Slip connections deliver a secure inlet seal and flexible outlet dispensing.
- 25mm membrane diameter for balanced throughput and low hold-up volume.
- Supplied nonsterile, 100 filters per pack.
These filters maintain reliable, repeatable filtration performance across routine and critical sample preparation. Low protein binding preserves sample integrity and analyte recovery, while the PFAS-free design supports clean, defensible results in demanding analytical workflows.
