Cambridge Isotope Laboratories, Inc. Embarks on Largest Expansion Project in the Company’s History

In 1990, CIL constructed the world’s largest ¹³C isotope-separation plant, CIL Isotope Separations, LLC (CIS), located on 33 acres in Xenia, OH. Since then, the site has grown to 48 acres and there have been four expansions of ¹³C production. This investment, which began in 2020, is planned to be completed in 2024 and will dramatically increase CIL's existing capacity of ¹³C production.

“North Star is a culmination of 30 years of knowledge and learning how to design, build, and operate isotopic separate systems,” states Mike Steiger, Vice President of Engineering and Project Execution at CIS. “Our experience allows us to continually make improvements in our design, execution of the project, and operation of our systems.” 

“With each build and expansion of ¹³C, CIL accumulates vast amounts of information and learning,” says CEO Cliff Caldwell. “Although our earliest systems are fully operational and have been for decades, we continue to challenge what we know and can learn from each expansion to increase efficiency, reliability, and redundancy while reducing our environmental footprint. We are passionate about not just being the biggest but also the best.”

¹³C is a critical starting material used in the production of new and existing research and diagnostic chemicals. North Star will ensure that CIL’s committed, long-term customers will be guaranteed the additional ¹³C required for the current and increasing future demands for ¹³C-labeled compounds.
