The National Institute of Diabetes and Digestive and Kidney Diseases requires a Whole Body Composition Analyzer to measure fat mass, lean mass, and body water in live mice, replacing a 17-year-old non-operational system. The instrument must provide rapid, non-invasive measurements without anesthesia, with a scan time of approximately 1–2 minutes per mouse. It will be shared across multiple laboratories to support research in obesity, diabetes, and related metabolic disorders. No budget amount or performance location is specified in the description. No submission or non-bid timelines are mentioned.
