Avantor, Inc. announced the expansion of its North American quality control capabilities with the addition of advanced microbial and stability testing at its St. Louis manufacturing site. The investment builds on Avantor's established global quality infrastructure, expanding and localizing capabilities to better support U.S.-based biopharma manufacturing and further accelerate service for customers.

Expands GMP-aligned microbial testing and ICH-compliant stability testing and storage in North America. Localizes testing previously conducted across third-party labs and Avantor's global network, bringing critical capabilities closer to U.S. manufacturing operations. Supports 2,000+ microbial samples annually within Avantor's internal network.

Enables faster turnaround times, improved data visibility, and reduced supply chain complexity. The enhanced St. Louis facility now offers integrated microbial and stability testing aligned with global regulatory standards, supporting regulated biopharma applications and reinforcing Avantor's commitment to quality, compliance, and customer service.

By consolidating these capabilities into a single North American location, Avantor reduces reliance on external laboratories and minimizes cross-border sample movement, improving efficiency while maintaining consistent global quality standards. Integrating testing into one location enables accelerated time to market, more interconnected lab compliance and in-house expertise, and more streamlined operations across the biopharma supply chain. The facility is designed to support customer transparency and regulatory needs, including audit-ready laboratory space, advanced stability storage for high-value materials such as APIs and excipients, and capabilities that support more efficient, centralized testing and faster product development timelines.
