• Polyethersulfone (PES) Disc membrane

Polyethersulfone (PES) Disc membrane

Product Description

The highly asymmetric pore structure of MS® PES flat membrane offers a high dirty loading capacity, higher through-puts and higher flow rates than symmetrical membranes. PES (Polyethersulfone) membrane is hydrophilic and constructed from Polyethersulfone polymer membrane. It is designed to remove particulates during general filtration, and its low protein and drug binding characteristics make it ideally suited for life science application.


  • Inherently hydrophilic
  • Low protein binding characteristics
  • High Flow Rate
  • Superior thermal stability


  • Water filtration
  • Especial chemical reagent filtration
  • Liquid of high temperature filtration
