The National Institute of Standards and Technology (NIST) is seeking information from contractors capable of modernizing the console, cryoplatform, cryoprobe, and electronics of its existing Bruker 600MHz and 900 MHz NMR systems, which are beyond end-of-life. All new components must interface directly with the current Bruker magnets and be controllable by Bruker’s Topspin 5.0 or greater software. NIST anticipates issuing a Request for Quotation in the third quarter of FY26 and awarding a contract by the fourth quarter of FY26. Performance of services will be at NIST’s location in Gaithersburg, Maryland. No budget amount is specified in this sources sought notice.
