The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to award a service contract for the LSM880 Airyscan FAST confocal microscope manufactured by Carl Zeiss Microscopy, Inc. The primary objective of this procurement is to secure comprehensive repair and preventative maintenance services to ensure the operational efficiency of the microscope, which is critical for research on hearing disorders conducted by the Laboratory of Molecular Genetics. Interested vendors must submit a capability statement to the Contracting Officer, Sharmaine Fagan, at sharmaine.fagan@nih.gov by July 11, 2025, at 10:00 A.M., as the government plans to negotiate with only one source under FAR 13.106-1(b). The contract is expected to be awarded approximately five days after the notice, with a performance period of one year plus an option for an additional year.
