NIST - Custom UHV Flow Cryostats

The National Institute of Standards and Technology (NIST) is seeking custom ultra-high-vacuum (UHV) flow cryostats for its Ion Storage Group, specifically for quantum computing, quantum simulation, and optical clock experiments. The procurement involves three custom flow cryostats that must be fully compatible with a ColdEdge Stinger recirculating helium gas closed-cycle cooling system. Critical technical requirements include a central cold finger capable of cooling to 4 K with 500 mW cooling power, a radiation shield with 20 W cooling power at 40 K, and precise UHV compatibility specifications. The agency is conducting market research to identify potential vendors, with interested businesses required to submit a four-page electronic capability statement to Matthew Delgado via email by June 16, 2025. Vendors must demonstrate expertise in analytical laboratory instrument manufacturing under NAICS code 334516 and provide comprehensive details about their manufacturing capabilities, product specifications, lead times, and country of origin.

While no specific set-aside has been definitively established, NIST indicates a preference for small business opportunities and will pursue a small business set-aside if at least two qualified small businesses are identified. The procurement requires a turnkey solution with installation services, software, and electronic manuals, with a strict delivery and installation timeline of 18 weeks after order receipt. The government plans a 7-business-day acceptance testing period, and the contract does not specify additional training or maintenance requirements beyond standard manufacturer warranties. All in-vacuum components must meet stringent dimensional constraints, with a maximum outer diameter of 1.500" to ensure compatibility with existing experimental apparatus. The solicitation emphasizes UHV compatibility, requiring all materials and components to meet ultra-high-vacuum service requirements, which will likely be a critical evaluation criterion for potential vendors.
