Pegasus Protect membrane in Microdisc capsules

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.

Both gamma irradiated and non-irradiated Microdisc capsules containing Pegasus Protect media are optimized for the confirmation and validation of performance at a small scale using minimal volumes of process fluid.

Performance established during small scale trials can be easily scaled as both Pegasus Protect prefilters and Pegasus Prime virus filters are available in a range of optimized capsule and filter formats which maintain a constant area ratio between prefiltration and virus filtration at all scales.

All process scale devices can be integrated into single-use and automated solutions to offer the highest degree of control, flexibility and security.
