About the company
ZEF Scientific, Inc., a Lake Forest, California–based small disadvantaged business subsidiary of Shimadzu Scientific Instruments, Inc., provides maintenance, repair, and relocation services for analytical instrumentation — primarily mass spectrometry and liquid chromatography systems — as a prime contractor to civilian federal research agencies. ZEF Scientific operates entirely through prime purchase orders, with no subcontract presence across its federal portfolio.
ZEF Scientific's capability footprint centers on field maintenance, preventative service, emergency repair, and onsite technical support for sophisticated analytical instruments deployed across federal laboratories. Representative work includes a $768,600 five-year firm fixed-price purchase order awarded by the National Cancer Institute in June 2026 for maintenance and repair of Thermo Orbitrap Lumos and Exploris 240 mass spectrometer systems at the Clinical Cancer Metabolism Facility in Bethesda; a $277,152 three-year purchase order from the USDA Western Regional Research Center awarded in September 2025 covering three LC-MS/MS systems (4000 QTRAP, QTRAP 6500, and Triple Quad 4500) in Davis, California; and a $115,457 five-year total small business set-aside purchase order from the U.S. Geological Survey awarded in February 2025 for comprehensive preventative maintenance and emergency repair of an AB/Sciex API 5500 triple quadrupole mass spectrometer at the Kansas Water Science Center. Work is performed at the customer location — Bethesda and North Bethesda, Maryland; Davis, California; Lawrence, Kansas; Durham, North Carolina — with service levels typically including two preventative maintenance visits annually, unlimited technical support by phone, and onsite response within one to two business days.
ZEF Scientific's customer concentration aligns with federal research infrastructure. The National Institute of Environmental Health Sciences accounts for 6 awards and $888 thousand in combined potential value; the National Cancer Institute, $769 thousand (1 award); and the USDA Pacific West Area and the USGS Office of Acquisitions and Grants together represent $687 thousand across 6 awards. These five organizations account for 88% of ZEF Scientific's combined potential value. The Environmental Protection Agency's Office of Research and Development and the Food and Drug Administration complete the active customer set.
Activity has remained modest but consistent. ZEF Scientific earned three awards in 2026 (as of mid-July), two in both 2025 and 2024, and one in 2023. Combined potential value across the entire 27-award prime portfolio stands at $3 million, with $1.8 million obligated. One award (the USDA Davis PO) reaches ultimate completion inside the next twenty-four months, presenting a single recompete opportunity valued at $277 thousand.
ZEF Scientific operates as a division of Shimadzu Scientific Instruments, Inc., a foreign-owned, for-profit corporate parent that itself holds federal contract prime awards and GSA vehicle seats. The parent company's broader federal presence and analytical instrumentation distribution network provide ZEF Scientific access to a steady flow of maintenance and support opportunities across NIH centers, USDA research facilities, and EPA field laboratories, but ZEF Scientific's awards are exclusively its own, not routed through the parent vehicle.
