The Department of Health and Human Services, specifically the Food and Drug Administration (FDA), intends to award a sole-source contract to Nikon Instruments Inc. for a Preventive Maintenance Agreement for a Nikon Inverted Confocal Microscope. This contract is essential for maintaining the microscope's operational capacity and will cover two one-year maintenance periods following the expiration of the current service agreement on December 31, 2024. The microscope is crucial for the FDA National Center for Toxicological Research's Division of Neurotoxicology, which relies on it for live-cell imaging, making uninterrupted service vital for ongoing research efforts. Interested parties may submit a capability statement to Yolanda Rankin at yolanda.rankin@fda.hhs.gov by November 18, 2024; if no responses are received, Nikon will be awarded the contract.
