Tall AccuRotor Four Animal Rotarod
The Tall AccuRotor Rotarod provides a 64 cm fall height and 7 cm rod diameter, supporting up to four subjects at once. It combines smooth, controlled motorized rotation with customizable software-based trial design. With optical fall detection, individual lane controls, and simple USB connectivity, the system offers a reliable and adaptable platform for motor coordination testing in rats.
Overview
The Tall AccuRotor Computerized Rota-Rod is a four-lane system for motor coordination testing, featuring an extended 64 cm fall height. This configuration includes a 7 cm diameter rotating rod, suitable for use with rats, and delivers smooth, precise rotation through a DC servo motor. Speeds range from 0.0 to 100.0 RPM, with adjustable acceleration and deceleration up to 40 RPM per second, in both clockwise and counterclockwise directions.
Each of the four 110 mm wide lanes includes optical fall detection, a start button, status indicator, and removable waste tray. The enclosed chamber below each rod helps minimize cross-lane interference following a fall. A built-in lock-out mechanism prevents subjects from unintentionally rotating the rod.
The system operates through the included Fusion software, which is compatible with Windows 7, 10, and 11. Users can run constant-speed trials or create custom acceleration profiles using the Acceleration Profile Editor, including options for forward and reverse motion as well as looping. Trial results such as fall time, rod speed at the time of fall, and experiment configuration can be exported in Excel-compatible .CSV format.

AccuPacer Mouse Treadmill
The Omnitech AccuPacer Treadmill is designed for studying exercise-related paradigms such as muscle atrophy, stress, running, and fatigue in animals. It features a belt driven by a DC servomotor for precise speed control, adjustable from 0 to 100 meters per minute, with an optional motorized grade adjuster for incline. Each animal runs in its own separated lane, with individual shock grids for training, and the treadmill uses both negative and positive stimuli to reduce training time. Additional features include independent lanes, waste collection trays, and air-tight runways for optional integration with a metabolic system.

AccuRotor EzRod
The AccuRotor EzRod is a rotarod system designed for testing balance and coordination in mice and rats. It works with Fusion software to set up trials at constant speeds or with variable acceleration. The system automatically stops when a fall is detected by infrared sensors. The Fusion software can manage up to 16 EzRods per computer, allowing researchers to quickly start new tests after a subject falls, making it ideal for high-throughput experiments.

It uses a precise DC servo motor for smooth rotation, with speeds ranging from 0.0 to 100.0 RPM, and can handle complex acceleration profiles, including forward/reverse rocking. The system includes fall detection via optical sensors, eliminating issues with mechanical systems, and records trial duration or fall counts. It supports up to four animals simultaneously, with adjustable lanes and easy-to-use software that offers trial customization, real-time data recording, and export to Excel. The system is adaptable for both mice and rats, with removable rat adapters, and provides simple USB connectivity for easy setup.
Activity Wheel
The Activity Wheel is designed to measure voluntary physical activity in rodents, making it an essential tool for research in exercise physiology, motivation, and circadian rhythm regulation. By capturing running behavior in real time, the wheel allows researchers to assess activity patterns, endurance, and daily rhythmicity. Integrated with a magnetic sensor and Fusion Software, it provides precise, automated tracking of wheel revolutions. The standard 6.5” wheel suits mice, with optional sizing for rats or custom needs. An optional Dual Wheel Kit enables simultaneous testing of two animals, supporting high-throughput, behaviorally relevant data collection in a naturalistic and enriched environment.
