PES Flat Membrane

PES membrane is natural hydrophilic, good wettability and asymmetric pore structure

PES membrane is a natural hydrophilic, with good wettability and an asymmetric pore structure, so it has a super high water flux. PES membrane is known for its thermal stability, durability, and resistance to acidic and alkaline solutions. It shows very low protein adsorption and low extractable levels. Widely used in filtration applications in the fields of food and beverage, biopharmaceuticals, microelectronics, industry, water treatment, and laboratories.

FAQ

The PES Membrane (Polyethersulfone) is widely used for sterile filtration, buffer preparation, and cell culture media clarification. Its high porosity and asymmetric structure make this PES membrane ideal for removing bacteria and particulates while maintaining high flow rates in critical pharmaceutical processes.

Our PES Membrane features naturally low protein binding characteristics. This ensures maximum recovery of high-value active pharmaceutical ingredients (APIs). Compared to other materials, the hydrophilic nature of the PES membrane reduces the risk of clogging and protein loss during the filtration of sensitive biological fluids.

Yes, Tailin provides the PES Membrane in various pore sizes and dimensions to meet specific application needs. Every PES membrane undergoes rigorous quality control and integrity testing to ensure it meets the highest standards for flow rate and retention efficiency.
