This contract, governed by Federal Acquisition Regulation for sole source acquisitions, will provide comprehensive service coverage essential for maintaining accuracy in bacterial analysis and ensuring compliance with clinical regulations. As the Original Equipment Manufacturer (OEM), Bruker is uniquely qualified to service this complex instrument, and market research has confirmed that no alternative providers are available. The anticipated award date is November 26, 2024, and interested vendors may contest this sole source designation by contacting Kenyadah M. Gamble at xvw0@cdc.gov or Philip Denis at icx2@cdc.gov before the specified deadline.
