Polyethersulfone (PES)

Hydrophilic membrane. designed to remove particulates during general filtration, low protein and drug binding characteristics make it ideally suited for use in life science applications. Its strength and durability are advantageous during usage that involves aggressive handling or auto- mated equipment. Low protein and drug binding characteristics maximize recovery of critical drugs used in I.V. therapy, chemotherapy and open-heart surgery.


Features and Benefits:

  • Very Low Protein Binding
  • Fast Flow Rates
  • Low Extractables
  • Wide Chemical Compatibility Range
  • Strength and Dimensional Stability
  • Autoclavable



  • Protein and enzyme filtration sterilization
  • Biological fluid filtration sterilization
  • Tissue culture media sterilization
  • Pharmaceutical sterilizing filtration
  • Environmental water studies
  • Filtration of Aqueous Solutions
  • Analytical Sample Prep, uHPLC
