Thumbnail Filmstrip of PES Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Slip, Transparent, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic polyethersulfone (PES) membrane with a 0.22um pore size, these syringe filters deliver fast, low-protein-binding clarification of aqueous and organic solutions. The 13mm membrane is housed in a transparent polypropylene shell with an 18mm housing diameter and provides an effective filtration area of 0.76 cm squared. Each unit is PFAS-free, nonsterile, and ultrasonically welded for integrity, and arrives 100 per pack.
Key PES Membrane Characteristics
- Naturally hydrophilic polyethersulfone membrane requires no wetting agents or surfactants.
- Low protein and drug binding maximizes sample and analyte recovery.
- 0.22um pore size removes fine particulates and microorganisms during general filtration.
- Broad chemical compatibility supports filtration of acids, bases, buffers, serums, and solvents.
- PFAS-free construction suits trace-level analytical workflows.
Key Construction Characteristics
- Transparent polypropylene housing with an 18mm housing diameter and 13mm membrane diameter.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
- Effective filtration area of 0.76 cm squared with a holdup volume of less than 50 microliters.
- Maximum operating temperature of 90 degrees C (194 degrees F) and maximum operating pressure of 80 psi.
- Nonsterile, supplied 100 per pack.
The ultrasonically welded housing is integrity tested to ensure a proper fit and weld, eliminating potential filter bypass. The low holdup volume and improved flow channel design preserve sample integrity and recovery, even with small or costly volumes. These characteristics provide reliable, repeatable clarification for routine and critical filtration tasks.
