Metabolic Measurement System and Treadmill for Human Metabolic Research

The National Institutes of Health, through the Phoenix Epidemiologic and Clinical Research Branch of the National Institute of Diabetes and Digestive and Kidney Diseases, is seeking to acquire a fully integrated metabolic measurement system and research-grade treadmill to replace an aging unit that is nearing the end of its operational life. The system must precisely measure oxygen consumption, carbon dioxide production, ventilation, and energy expenditure in human participants during both resting and graded exercise conditions to support critical research into metabolic diseases such as obesity and diabetes. The required equipment package includes the Parvo TrueOne 2400 metabolic measurement system with integrated gas analyzers and automated calibration, a TrackMaster TMX428CP treadmill capable of speeds from 0.1 to 15 mph and inclines up to 25 percent, a Dell Pro Slim QCS1255 computer with data analysis software, and all necessary accessories such as masks, circuits, calibration tools, and a printer. The system must function as a validated, interoperable unit capable of breath-by-breath gas analysis and seamless synchronization with treadmill protocols during physical testing. Delivery is required at the branch’s facility in Phoenix, Arizona, with mandatory lift gate and white glove service for installation, and the vendor must provide on-site operational training covering system calibration, treadmill operation, and data acquisition procedures. The contract will be awarded under a firm fixed-price purchase order with payment made in a single lump sum upon successful delivery, installation, acceptance, and completion of training. The equipment must be covered by a minimum three-year warranty for the gas analyzer, pneumotach, and computer system, and a one-year warranty for the printer. Optional features such as a canopy dilution system, extended warranties, and specific mask configurations are available but not required. The solicitation, identified as PACNIDDK0807POTS26004031 and posted on May 11, 2026, with a response deadline of May 21, 2026, does not include detailed evaluation factors, pricing data, or specific contract clauses typically found in full solicitations, as it is a presolicitation notice. While technical specifications are detailed and performance expectations are clearly defined, there are no explicit references to federal standards like ISO or ASTM, no socioeconomic set-asides, no representations or certifications required from offerors, and no mention of inspection checklists beyond functional performance criteria. The acquiring office is located in Bethesda, Maryland, but the system must be delivered, installed, and accepted in
