Solicitation - Sub-Kelvin Cryostat

The National Institute of Standards and Technology seeks quotes for a sub-kelvin cryostat system with optional upgrades. Key requirements for the cryostat include a base temperature below 900 millikelvin, over 1.3 watts of cooling power at 4.2 kelvin from a pulse tube cooler, three KF25 vacuum ports, a gold-plated OFHC copper experimental plate over 250mm in height and 125mm in diameter, a 12-hour cooldown time, and full manufacturer warranty. Quotes will be evaluated based on technical acceptability and price, and are due by June 30, 2023.

There is no set-aside designation. The NAICS code is 334516 and PSC code is 6515. Delivery of the cryostat system is required to NIST in Boulder, Colorado between May 1 and December 1, 2023. Quotes must also provide pricing for optional upgrades including a dilution refrigerator unit providing over 250 microwatts of cooling at 100 millikelvin and 40+ gigahertz bandwidth wiring for two HEMT amplifiers. Award will be made based on best value to the government.
