Hydrosart® Ultrafilter

Hydrosart® membranes are stabilised cellulose-based membranes that have been optimised for applications in the biotechnological and pharmaceutical industries. The Hydrosart® membrane consists of a stable polymer and can be used in a wide pH range. It is also extremely hydrophilic, which almost completely prevents the binding of proteins and fouling processes, and is characterised by extremely high flow rates.

The regeneration, storage and depyrogenation of these membranes can be carried out with NaOH even at elevated temperatures. These features make Hydrosart® the ideal membrane for biological applications. Hydrosart® ultrafiltration cassettes are available with a nominal molecular weight cut-off (MWCO) of 2 kD / 5 kD / 10 kD / 30 kD and 100 kD.

Compliance with regulatory requirements

All materials comply with the current USP Biological Testing regulations. In terms of total solids, oxidisable substances, particulate contaminants, ammonium, chloride, nitrate, sulphate and the filtrate meets or exceeds the USP and EP requirements for sterile water for injection.

Quality control: Each filter cassette is given its own serial number and is tested and certified for integrity. It meets the cGMP requirements for non-fibre-releasing filters and is listed by the US Food and Drug Administration (FDA) under the Drug Master File number DMF 5967.
