Our Rota Rod (or rotarod) provides an easy way to test the effects of drugs, brain damage, or diseases on motor coordination or fatigue resistance in rodents.
The animal is placed on the rotating lane of the Rota Rod and the timer is started. When the animal drops safely into its own lane, the time latency to fall (minutes and seconds) and rotation speed are automatically recorded. A removable upper separator for rat models is included to prevent interference between animals running in adjacent lanes.
The Rota Rod is controlled by an advanced microprocessor which provides precise timing control and ultra-accurate speed regulation. Rotation can be electronically set at a constant speed (4-40 rpm). Alternatively, acceleration rate may be selected at a defined time (30 sec to 10 min, 1 sec increments). Acquired data is saved in table form by lanes/trials.
Now even easier to use! The new touchscreen graphic user interface allows clear visualization of timing and speed for each lane. Change modes, adjust speed, and create protocols right from the main screen for greater flexibility with maximum functionality and usability.
Parameters Measured:
- Animal latency to fall
- Rotation speed when fall occurs
Key Features:
- NEW Touchscreen User Interface
- Combined Rota Rod for mice and rats available
- Mechanical detection of fall
- Individual lane timers
- Constant speed and fixed acceleration rate modes
