The Single-Use Venting Filter
Highest Venting Performance meets the Requirements for your Single-Use Application
Sartopore® as a leading and trustworthy brand name is a synonym for high-performance sterilizing-grade filters using polyethersulfone (PES) membranes. Now Sartopore® opens up a new field of applications. Our new hydrophobic PES membrane is the ideal choice for sterile venting of your single-use systems, clearly outperforming all PVDF filters in this field of play. This allows economic downsizing of the filters without affecting the overall performance. This outstanding new membrane material provides unique advantages for your process. Sartorius Stedim Biotech is the only provider of hydrophobic PES filters from small to large scale.
Midisart® Sartopore® Air
Best Performance Needs Only Little Space
Our High Runner for Small Venting Applications
The new, gamma irradiatable Midisart® is developed to meet the requirements for your critical small-scale venting applications, accurately fitting to your processes. Particle retention, particle release limits, phage retention and of course bacteria retention in air and liquids (bi-directional) are specifications that proof the quality of Sartopore® Air Midisart®. Superior and steady flow rates over long duration imply highly efficient processes.
