The National Institute of Standards and Technology (NIST) is seeking to negotiate a sole source contract for maintenance services of its Montana Instrument Cryostat, specifically requiring the replacement of the cryocooler and compressor adsorber. This maintenance is critical as the cryostat is a specialized piece of equipment originally manufactured by Montana Instruments, and only the original manufacturer possesses the necessary expertise to service it without risking damage or complete failure. Interested parties that can demonstrate their capability to fulfill these requirements must submit their qualifications in writing to Angela Hitt at angela.hitt@nist.gov by the specified response date, with an estimated award date of November 17, 2024.
