The Dukal Corporation-4450 Minute Minder Timer is a reliable mechanical tracking instrument designed to keep precise time for laboratory tests, clinical diagnostic incubations, therapy sessions, and general procedural timing. Requiring no batteries or electrical outlets, this analog kitchen-style timer features a large, high-visibility dial face with clear 1-to-60 minute demarcations. Users simply turn the dial past the 50-minute mark to fully wind the internal spring mechanism, then rotate back to the desired duration. When the countdown completes, a clear single chime alerts staff. Built with an impact-resistant white plastic housing and a stable flat base, it sits securely on counters, lab benches, and treatment carts in hospitals, clinics, and school science labs.
