Scalable Solutions

Prefiltration area and flowrate are critical variables that may affect the performance of Pegasus Protect prefiltration and Pegasus Prime virus removal filters when used in combination.

To control these variables Pegasus Protect prefiltration media is available in a range of formats, designed to maintain a consistent pre-filter to virus-filter ratio. This control ensures predictable and consistent performance at all scales from the initial Microdisc scale trials to clinical manufacturing.
