What are the challenges of PUPSIT?
The challenges of PUPSIT are mainly about maintaining sterility, ensuring correct testing and obtaining reliable data. It requires that the system is built without creating new risks of leakage or contamination, that the filters are fully wetted to avoid false failures, and that test sequences and settings can be accurately repeated with full data traceability. To succeed, a solution is needed that provides good process control, repeatability and easy data collection - without complicating production.
