About the company
Cambridge Isotope Laboratories, Inc., doing business as Cambridge Isotope Labs, manufactures stable isotopes and isotope-labeled compounds for biomedical research as a foreign-owned prime contractor competing in full and open procurements, with no set-aside participation across its federal footprint. The company is headquartered in Andover, Massachusetts and operates across primary NAICS categories including All Other Basic Organic Chemical Manufacturing (200 awards) and Biological Product Manufacturing (17 awards), with PSC codes anchored in Chemicals (130 awards) and Laboratory Equipment and Supplies (77 awards).
Cambridge Isotope Labs holds a $100 million single-award Blanket Purchase Agreement with the National Institutes of Health Office of Logistics and Acquisition Operations running through January 31, 2027, which underpins the bulk of its recent federal revenue. The vendor supplies deuterium oxide, deuterated glucose, isotopically labeled amino acids, and custom-labeled compounds used in metabolic tracing, nuclear magnetic resonance experiments, and protein turnover studies across multiple NIH institutes. Representative task orders under the NIH BPA include a $24,975 call from the National Heart, Lung, and Blood Institute in September 2025 for deuterium oxide to produce deuterated proteins for NMR experiments, and a $16,200 order from the National Institute on Aging in May 2024 for deuterated glucose at 99% purity to support mitochondrial protein turnover research. Outside the BPA framework, Cambridge Isotope Labs has filled purchase orders for specialized isotopic materials: a $221,095 order from the CDC in September 2025 for five First Tier Newborn Screening Internal Standard Kits (lyophilized isotopically labeled internal standards), a $74,945 order from the National Institute of Standards and Technology in September 2026 for stable isotopes for biologics, and a $58,585 order from the CDC Pittsburgh office in August 2024 for 2nd Tier Newborn Screening Kits and Metabolite Standard Mixes.
Customer concentration tracks heavily to the Department of Health and Human Services. The top five funding agencies account for 54% of combined potential value, led by the CDC Office of Acquisition Services (55 awards, $3.8 million), the CDC Pittsburgh office (22 awards, $1.1 million), and the NIH National Institute of Diabetes and Digestive and Kidney Diseases (29 awards, $601 thousand). The source identifies 44 distinct customer agencies overall. Activity has grown from five awards in 2022 to a peak of thirteen awards in 2024, with nine awards placed in 2025 and two in 2026 year to date. One award with combined potential value of $75 thousand reaches ultimate completion within the next twenty-four months, representing minimal recompete exposure in that window. Cambridge Isotope Labs subcontracts minimally — the source names only two sub-awards, both to Valkyrie Enterprises, LLC (one in July 2025 for DOD gases and one in December 2024 for MIT Lincoln Laboratory gases). Work is performed at the Andover, Massachusetts facility with distribution to multiple NIH component locations and other federal agencies.
