The Department of Health and Human Services, specifically the National Institutes of Health (NIH) and the National Cancer Institute (NCI), is seeking to procure sole-source preventive maintenance services for one Illumina Microarray Scanner (iScan/RoMa) and two Illumina Sequencers (NextSeq 550Dx) from Illumina, Inc. The procurement aims to ensure that these critical instruments, used for high-throughput diagnostic assays essential for patient care and clinical trials, are maintained according to the manufacturer's specifications to guarantee data accuracy and system reliability. This maintenance is vital for the integrity of ongoing clinical research and compliance with clinical laboratory standards, as any instrument failure could jeopardize patient safety. Interested parties, particularly small businesses, may submit capability statements by April 2, 2025, to Contract Specialist David Romley at David.Romley@nih.gov, with the contract period expected to run from July 1, 2025, to June 30, 2026.
