overview

Ready-to-Sterilize

West's validated wash process, Westar RS, is used to produce components that are ready for gamma or steam sterilization. Westar RS stoppers 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, is applied after the Westar RS wash process to produce components for direct introduction into filling operations. Westar RU components help manage regulatory and compliance risk, facilitate equipment and space management, and reduce ongoing validation activities.

The Westar RU and RS processes are supported by a DMF.
