In order to test the quality of each individual vial, a non-destructive detection of this partial vacuum is necessary at a high throughput rate.
The GNT PASS process provides high test reliability at a clock rate of up to 10 vials per second.
For the first time, GNT systems with PASS technology offer information beyond a good/non-good test by capturing and recording quantitative pressure values. Trends in production quality are identified and process fluctuations can be compensated in good time.
This makes 100% quality control possible – at the end of the production line or packaging process. Hence, a continuous control of the vacuum and a monitoring of the predefined negative pressure inside the vessels can be assured.
