The Department of Health and Human Services, specifically the National Institutes of Health (NIH) through its National Institute of Allergy and Infectious Diseases (NIAID), intends to negotiate a sole-source service contract with FEI Company for the maintenance of a DB SW FEG QUANTA 3D microscope. This premium service agreement is crucial for ensuring the operational integrity and longevity of the microscope, which is valued at over three million dollars, by providing specialized emergency support and expert technicians trained specifically for this equipment. The service contract aims to minimize downtime and prevent costly replacements, thereby supporting the NIAID's biodefense clinical research initiatives. Interested vendors capable of providing comparable services are invited to submit a capabilities statement via the NIAID electronic Simplified Acquisition Submission System (eSASS) by 12:00 PM EST on May 26, 2025, with further details available through the provided contact information: Maliaka Pinkney at maliaka.pinkney@nih.gov or Jesse Weidow at weidowjd@niaid.nih.gov.
