Pegasus™ Prime membrane in Microdisc capsules, a Pall Life Sciences product, are for the confirmation and validation of performance at a small scale using minimal volumes of process fluid and virus spike preparations. Pegasus Protect virus prefiltration combines with Pegasus Prime virus filtration to deliver the first gamma-sterilized pre-filter and virus filter combination. Together, these simplify process development, validation and operations while saving time and delivering improved process economy. Process developers can quickly deliver a robust, scalable virus filtration process using a minimum of sample volume, and be confident of successful virus validation. This choice supports clinical manufacturing with a solution that is easy to use and versatile to work alone or with integrated and automated single-use systems. The Microdisc capsules containing Pegasus Prime virus media are ideal for the confirmation and validation of performance at a small scale using minimal volumes of process fluid and virus spike preparations and deliver consistently high log reduction value (LRV) irrespective of the virus validation choices.The predicted process flow, filter capacity or virus retention established during these studies scales to a range of products available to support your process at all scales and offer the highest degree of manufacturing control, flexibility and security.
