The National Institutes of Health (NIH) intends to award a non-competitive, firm-fixed price purchase order to Mediso USA LLC for an annual full-service maintenance contract on two Mediso MultiScan LFER PET/CT animal imagers. The services are required for instruments located in Bethesda, MD, to support tuberculosis research at the NIAID Division of Intramural Research. The contract is justified as a sole-source award because only the original manufacturer can service the unique equipment without voiding the warranty, which expires in June 2026. No budget amount is specified in the description. Responses to this notice are due by June 26, 2026, at 12:00 PM Eastern Time.
