Hydrosart® is a stabilized cellulose derivative membrane polymer that has been optimized for the biotechnological and pharmaceutical industries. The Hydrosart® membrane is a stable polymer that features a broad pH and temperature range. Hydrosart is also extremely hydrophilic, making it non-proteinbinding and virtually non-fouling. As a result, it has extremely high flux. Hydrosart®’s 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. Hydrosart® membranes are designed for use in the biotechnological and pharmaceutical industries.

They can be used to remove the following from liquids:

  • Mammalian cells: CHO BHK
  • Bacteria: E. coli Pasteurella C. diphtheria
  • Yeasts
  • Cell Iysates Product

Hydrosart® has minimal adsorption of proteins, viruses, etc. Membrane retention is unaffected by repeated re-use. Hydrosart® has been validated to withstand in-line steam sterilization without any loss of integrity or changes in membrane retention.
