Stainless Steel Bioreactors, Fermentation Vessels, and Batch Reactors

At HOLLOWAY AMERICA, we engineer stainless steel bioreactors and fermentation vessels to exacting specifications because we understand the critical nature of Pharmaceutical and Biotech industries.

In fact, we excel at meeting those standards.

We’re passionate about crafting completely customized processes that meet your most unique or challenging specifications. We also use high-quality finishes that exceed industry norms. Each vessel we craft is inspected and tested to ensure all requirements are met or surpassed. When you size your vessels and design your fermentation or bioprocessing suites, you can rely on our reputation and dedication to ensure your processes are carried out with utter precision.
