Thumbnail Filmstrip of PES Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, Transparent, 100/Pk Images
Featuring a naturally hydrophilic polyethersulfone (PES) membrane in a PFAS-free construction, these syringe filters deliver rapid clarification of aqueous and organic solutions with a 0.45um pore size and a 25mm membrane diameter. The PES membrane provides low protein binding and broad chemical compatibility, while the transparent polypropylene housing offers chemical resistance and lets you monitor sample passage. Each unit pairs a Female Luer Lock inlet with a Male Luer Slip outlet for secure, flexible connection, and ships nonsterile in packs of 100.
Key PES Membrane Characteristics
- Naturally hydrophilic wets out readily for fast, consistent flow of aqueous samples without prewetting.
- Low protein binding maximizes recovery of proteins and other analytes of interest.
- Broad chemical compatibility suits a wide range of aqueous solutions, buffers, and many organic solvents.
- PFAS-free construction supports reliable analysis of PFAS-sensitive samples and reduces background interference.
- 0.45um pore size removes particulates for clarification and instrument protection.
Key Construction Characteristics
- Housing: transparent polypropylene for chemical resistance and visible sample flow.
- Connection: Luer-Lok inlet with Luer Slip outlet for secure, flexible attachment.
- Sterility: nonsterile.
- Pack: 100 filters per pack.
- Each filter is labeled with the specific membrane material and pore size for easy identification outside its original packaging.
This combination of a hydrophilic, low-binding PES membrane and an inert polypropylene housing maintains sample integrity through clarification and instrument-prep workflows. The 0.45um rating provides dependable particulate removal that protects downstream columns and detectors, and the PFAS-free build helps preserve accuracy in trace-level analyses.
