Product Description

PES Cartridges are manufactured with Polyethersulfone to guarantee uniform pore distribution, allowing for maximum bacteria retention. The upstream and downstream polyester support renders it completely resistant to pressure shocks. Being hydrophilic, the Polyethersulfone membrane facilitates easy integrity testing when daily controls are necessary. It is compatible with a broad range of chemicals and does not contain surfactants, offering an absolute rating for the most stringent filtration applications. It is commonly employed for sterile filtration in the production of Active Pharmaceutical Ingredients.
