The National Institutes of Health (NIH), specifically the National Cancer Institute (NCI), intends to procure preventative maintenance and emergency services for fourteen government-owned Zeiss microscopes, which are critical for cancer research conducted by the Laboratory of Cancer Biology and Genetics. The procurement will be conducted on a sole-source basis with Carl Zeiss Microscopy, LLC, the original equipment manufacturer, due to its proprietary software and the necessity for authorized service technicians to ensure compliance with manufacturer specifications. This maintenance contract is vital for maintaining the operational functionality of the microscopes, which play a significant role in biological specimen analysis. Interested parties, particularly small businesses, are invited to submit capability statements by January 6, 2025, to be considered for potential competitive procurement.
