The Department of Health and Human Services, specifically the National Institutes of Health (NIH) through the National Institute of Allergy and Infectious Diseases (NIAID), intends to negotiate a sole source contract with Leica Microsystems for an Annual Silver Support Plan maintenance agreement. This contract is essential for maintaining the operational integrity of various Leica instruments that are critical to ongoing infectious disease research, and it will include comprehensive support features such as repair parts, labor, two preventative maintenance visits annually, and technical support. Interested vendors must demonstrate their capability to provide prioritized service and include proof of OEM-trained technicians in their submissions. Proposals are due by March 11, 2025, and must be submitted via the NIAID electronic Simplified Acquisition Submission System (eSASS). For further inquiries, vendors can contact Leah Hinson at leah.hinson@nih.gov.
