NovaPure stoppers are offered in two leading West formulations, a bromobutyl and a chlorobutyl. Special handling and testing ensures compliance with the tightest particulate specification offered in each of these formulations. This specification, stated in parts per million (ppm), comprises visible and sub-visible measurements.
NovaPure stoppers are available in a range of familiar global designs selected for proven machinability and functionality and further enhanced through QbD-based principles of continuous improvement. Data gather, statistical analysis and knowledge management is an essential part of the NovaPure stopper quality process. In addition to the production feedback loop used to document critical processes and drive their improvement, all NovaPure stopper products undergo formal annual review.
NovaPure stopper business continuity is supported through West’s continuing investment in plants across our global network.
