Narrow Gap Activity Wheel for Physiological Research Instrumentation

The Narrow Gap Activity Wheel is designed for running rats or mice while supporting animal well-being and convenient maintenance. The wheel features a removable sensor/counter that can be detached without tools and does not require special alignment. Its narrow gap design reduces the space between the wheel rim and wheel support to 1/4 inch (6.35 mm) or less, helping prevent mouse escape or injury while allowing mice to be used in a large 14-inch diameter wheel. The system can also be used with rats, with the same core wheel specifications. Manufactured by Atico Export for reliable performance in rodent activity and behavioral research.
