The Department of Energy's National Energy Technology Laboratory (NETL) intends to award a sole source contract for the renewal of an annual service and maintenance agreement for the Physical Electronics PHI SAM 590 and PHI 548 UHV Systems. The contract will cover the period from September 16, 2025, to September 15, 2026, and includes one on-site visit, unlimited technical support, and factory repairs, excluding OEM equipment repairs and consumables. This maintenance is critical as RBD Instruments, Inc. is the only known source capable of servicing these proprietary systems, which utilize specialized hardware and software. Interested parties who believe they can meet the requirements must submit their capabilities in writing to Contract Specialist Shannon Lynch at shannon.lynch@netl.doe.gov by 1:00 PM EDT on August 8, 2025.
