Membrane filters serve as effective physical barriers that remove solids, viruses, bacteria, and other unwanted molecules. Specialized types are designed for softening, disinfecting, organic removal processing, and water desalination. The filters can be installed in compact, automated, or modular units. These strainers can be used as separators between stacked discs in a single filter holder during serial filtration. Membrane filters are virtually inert to chemical and biological agents, ensuring stability when filtering concentrated acids, alkalis, or oxidizers.

Membranes disques filtrantes, Ultipor®
Supplier: Cytiva (Formerly Pall Lab)
Membranes en nylon 6,6 pour la filtration des fluides pour l'industrie pharmaceutique, biotechnologique, électronique, agroalimentaire, et pour les applications analytiques. Ces membranes sont très résistantes aux contraintes mécaniques, chimiques et thermiques. Elles s'utilisent dans les deux sens, sont intrinsèquement hydrophiles, présentent des débits élevés, de faibles chutes de pression et très peu de substances extractibles. Le cas échéant, elles se stérilisent à la vapeur sans altération du débit ou du seuil de rétention.
