The National Institutes of Health (NIH), specifically the National Institute of Allergy and Infectious Diseases (NIAID), intends to negotiate a sole-source maintenance service contract with Meso Scale Diagnostics LLC for the servicing of MESO SECTOR S 600MM instruments located at its Gaithersburg, MD facility. The contract encompasses several service packages, including preventive maintenance inspections, repairs, and pre-contract inspections for specific instruments, with maintenance services set to commence between October 24, 2024, and April 17, 2025, and concluding on May 5, 2025. This procurement is critical for ensuring the operational reliability of laboratory equipment essential for research, and it mandates that vendors provide factory-trained technicians and OEM specification parts. Interested vendors must submit their capability statements and relevant documentation via the NIAID electronic Simplified Acquisition Submission System (eSASS) by 10:00 AM on October 18, 2024, as this opportunity is not a request for proposals.
