Sartocube® PES Cassette
PES membrane is a membrane polymer that is well established in the biotechnological and pharmaceutical industries. It is a stable polymer featuring a broad pH and temperature range. PES membranes are designed for use in the biotechnical and pharmaceutical industries.
Stable polymer featuring a broad pH and temperature range
- Minimal adsorption of proteins, viruses, etc.
- Membrane regeneration, storage and depyrogenation can be accomplished by using NaOH even at elevated temperatures
- Membrane retention is unaffected by repeated re-use
