Ready-to-Sterilize
West's validated wash process, Westar RS quality level, is used to produce components that are ready for gamma or steam sterilization. Stoppers with Westar RS quality level are available in a range of formulations, designs, and packaging options to help transition resource-intensive, non-core component preparation activities to an expert external partner.
Ready-to-Use
West's validated steam sterilization process, Westar RU quality level, is applied after the Westar RS quality level wash process to produce components for direct introduction into filling operations. Components with Westar RU quality level help manage regulatory and compliance risk, facilitate equipment and space management, and reduce ongoing validation activities.
The Westar RU and RS quality levels are supported by a DMF.
