This is a notice of intent to award a sole-source, firm-fixed-price contract to Thermo Fisher Scientific for a preventative maintenance agreement on specific centrifuge models. The services will be performed at the National Institutes of Health Clinical Center in Bethesda, MD. The contract is justified because Thermo Fisher, as the original equipment manufacturer, has exclusive access to necessary parts, tools, and expertise to maintain the equipment in compliance with strict FDA regulations. While this is not a solicitation, interested parties may submit a capability statement demonstrating equivalent service abilities for government evaluation.
