PES Roll Membrane
Microlab PES Roll Membranes have various pore sizes ranges from 0.1μm to 0.45μm, the width is 270mm. The highly asymmetrical pore structure of our Micro PES flat membrane offers a high dirt loading capacity, increasing the filtration performance to give higher throughputs and higher flow rates than symmetrical membranes.

Features and Benefits
● Broad chemical compatibility 
● Low protein binding and low extractables
● Long service life and high flow rates 
● Integrity testable
