Hydrosart® Membranes are stabilised cellulose based membranes that have been optimised for the biotechnological and pharmaceutical industry. The Hydrosart® membrane is a stable polymer that features a broad pH range.
Hydrosart is also extremely hydrophilic, making it non-protein binding, virtually non-foul and has extremely high flux. Membrane regeneration, storage and depyrogenation can be accomplished by using NaOH even at elevated temperatures.
These features make Hydrosart® an ideal membrane for biological applications. Hydrosart® ultrafiltration cassettes are available in the following nominal molecular weight cutoffs:
- 2 kD
- 5 kD
- 10 kD
- 30 kD
Hydrosart® ultrafiltration membranes are designed for use in the biotechnological and pharmaceutical industries. They can be used for the following applications: Oligonucleotide, proteins (albumin - even with 40% EtOH - , hemoglobin), coagulation factors (factor VIII, factor III), vaccines (tetanus, diphteria), monoclonal antibodies.
Hydrosart® shows minimal adsorption of proteins, viruses, etc. Membrane retention is unaffected by repeated use. The Hydrosart® ultrafiltration membrane can be re-used without any loss of integrity or performance. Hydrosart® ultrafiltration cassettes have been validated to withstand in-line steam sterilization without any loss or changes in membrane retention.
