The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is planning to negotiate a sole source contract for Environmental Transmission Electron Microscope (ETEM) services. The procurement aims to secure maintenance and service for a Titan 80-300 kV ETEM, which is critical for conducting specialized preventative maintenance and emergency repairs necessary for analyzing nanoscale materials under reactive conditions. Thermo Fisher Scientific, the manufacturer, is the only entity authorized to provide these services in North America, emphasizing the importance of having factory-trained personnel for such specialized equipment. Interested parties capable of meeting these requirements are invited to respond by 11:00 AM EST on March 15, 2025, with the contract being a Firm-Fixed Price purchase order under NAICS Code 811210, which has a size standard of $34 million.
