The NIH Office of the Director, Office of Acquisitions, intends a non-competitive firm-fixed-price award to Mechatronics USA LLC for a one-year full-service maintenance contract for the Lorrca ektacytometer (RR Mechatronics), covering annual preventive maintenance and all corrective repairs, labor, travel, and non-consumable parts. The award is a Notice of Intent conducted under streamlined commercial-item procedures and is not expected to exceed the simplified acquisition threshold. Mechatronics USA LLC is identified as the OEM’s sole U.S. sales and service provider, with system software, calibration, and proprietary parts restricted to the manufacturer and certified partners, and no other responsible source capable of performing the service. The requirement uses NAICS 334516 (Analytical Laboratory Instrument Manufacturing) with a 1,000-employee small-business size standard and is not set aside for small business. Incorporated clauses are those in effect through Federal Acquisition Circular 2026-01, effective 03/13/2026.
