About Cambridge Isotope Laboratories

Cambridge Isotope Laboratories, Inc. (CIL) is the world’s leading producer of stable isotopes and isotope-labelled compounds.

Founded in 1981 by Dr. Joel Bradley, an MIT-trained organic chemist, CIL has grown into a global organisation with over 700 employees and facilities across five countries.

CIL specialises in incorporating highly enriched, stable (non-radioactive) isotopes of:

  • Carbon ( 13C)

  • Hydrogen (2H / D)

  • Nitrogen (15N)

  • Oxygen (17O, 18O)

By replacing naturally abundant isotopes (1H, 12C, 14N, 16O) with enriched isotopes, compounds can be precisely traced and quantified using mass spectrometry (MS) and nuclear magnetic resonance (NMR) techniques.

CIL products are used worldwide in:

  • Academic research

  • Clinical diagnostics

  • Pharmaceutical development

  • Environmental analysis

  • Government laboratories

  • Industrial manufacturing

Manufacturing & Quality Capabilities

CIL produces more than 15,000 products and operates under internationally recognised quality systems, including:

  • ISO 13485

  • ISO/IEC 17025

  • ISO 17034

  • cGMP production capabilities

CIL was acquired by the Otsuka Group in 1998 and has continued expanding its global footprint and production capacity.

Facilities & Isotope Production

CIL’s headquarters are located in Tewksbury, Massachusetts, with primary production laboratories in Andover, Massachusetts.

Its isotope-separation facility in Xenia, Ohio houses:

  • The world’s largest 13C isotope-separation plant

  • One of the world’s largest 18O separation facilities

  • The world’s only commercial D2O enrichment columns

These facilities underpin CIL’s position as the global leader in stable isotope production.
