PES membrane is constructed of pure polyether sulfone polymer, it is a inherently hydrophilic membrane for aqueous filtrations.These hydrophilic membranes have high flow rates, low protein and drug binding characteristics, plays an important role in medical applications such as endotoxins removal and retention of fine particles and fungi. It is also the most common filter media of syringe filters in life-sciences laboratories.

We manufacture and supply a variety of PES membrane formats - you can order it in cut-to-size discs for easy use, or in rolls and sheets for further process on your own. Pore size of the PES membranes from us are available from 0.22um to 20 um, porosity and other properties tested for each and every bulk before delivery to make sure lot to lot quality consistency.

Features

• Hydrophilic
• Multiple pore size choice
• Low protein binding
• High flow rate
• High retention efficiency
• High thermal stability
• Lot-to-lot quality consistency
