The National Institute of Standards and Technology (NIST) is conducting market research to identify vendors capable of supplying a 4 Kelvin Closed Cycle Cryostat, with responses due by the date and time specified in the notice. This is a sources sought notice, not a solicitation, and no budget amount is specified. The government will use the results to determine if a small business set-aside is possible, and all responsible sources, including large and small businesses, are encouraged to respond. The location for performance is not specified, but respondents must indicate the country of manufacture. Interested parties should submit a capability statement of four pages or less, including product specifications and typical lead time, to the contract specialist.
