Polyethersulfone (PES) Filter Membrane

Polyethersulfone (PES) Filter Membrane Polyethersulfone (PES) Filter Membrane Disc Filter Membrane Analytical Laboratory

The highly asymmetric pore structure of 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
