Helium Reliquifiers for NMR Magnet

The NIH’s NIDDK division requires two custom helium‑reliquifier systems to continuously recycle helium for its 141 kG and 175 kG NMR magnets, eliminating costly and unreliable liquid‑helium deliveries. The contract will be awarded on a sole‑source basis to Bluefors Cryocooler Technologies, Inc., but other vendors may submit capability statements for consideration. Each system must fit the specific magnet dimensions, produce at least 3 L/hr of liquid helium, and be installed on the NIH Bethesda campus. • Two separate helium‑reliquifier units required (one for a Magnex 175 kG magnet, one for an Oxford Instruments 141 kG magnet). • Minimum production capacity: ≥ 3 L/hr of liquid helium, continuous operation. • Must be compatible with existing magnet enclosures in rooms B2‑33 (Building 5) and B2A‑04 (Building 8). • Capability statements due by 09:00 EDT, 25 Sep 2026; award expected ~5 days later. • Sole‑source solicitation; however, other qualified sources may be considered if they submit a capability statement. • Procurement under FAR 6.302‑1 (Only One Responsible Source).
