The Department of Energy's National Energy Technology Laboratory (NETL) intends to award a sole source contract to Rigaku Americas Holding, Inc. for annual service agreements related to the Rigaku Ultima III X-Ray Diffractometer and Rigaku ZSX Primus II WDXRF Spectrometer for the period of June 1, 2025, to May 31, 2026. This procurement is essential to ensure priority and expedited repair services for these critical laboratory instruments, which require exact replacement parts and proprietary service procedures that only the original equipment manufacturer can provide. Interested parties who believe they can meet the requirements must submit written evidence of their capabilities to the Contract Specialist, Anissa Beasinger, via email by 3:00 PM ET on May 7, 2025, as this notice is not a request for proposals and the government will determine whether to pursue competitive procurement based on the responses received.
