PESU Polyethersulfone membranes are membrane polymers that are well established in the biotechnological and pharmaceutical industries. The PESU membrane is a stable polymer that features a broad pH and temperature range. Its wide temperature range makes it possible to sterilize the membrane by either steam or autoclaving. Membrane regeneration, storage and depyrogenation can be accomplished by using NaOH even at elevated temperatures. Because of these features, the PESU membrane is ideally suited for biotechnological applications. PESU cassettes are available in 0.1 µm. Polyethersulfone membranes are designed for applications in the biotechnological and pharmaceutical industries.

They can be used to remove the following cells from liquids:

  • Mammalian cells
  • Clostridia
  • Yeasts
  • Salmonella
  • Mycoplasma reduction

Polyethersulfone can withstand in-line steam sterilization without any loss of integrity or changes in membrane retention. Membrane retention is unaffected by re-use.
