The National Institute on Environmental Health and Safety (NIEHS) intends to award a sole-source contract to Becton Dickinson (BD) Biosciences for the service and maintenance of specific flow cytometers located at its laboratories in Research Triangle Park, North Carolina. The contract has a potential total value not exceeding $7 million. The period of performance is a base year from April 20, 2026, to April 19, 2027, with one 12-month option. The justification for a non-competitive award is that BD is the OEM, and only it can provide the required proprietary parts, software, and certified technicians. This is a pre-solicitation notice of intent, and while not a request for proposals, the agency will consider capability statements from other potential sources.
