The RACS is designed for following animal movements without the use of swivels. The system is designed for using multiple lines carrying liquid, wires, optical fibers etc. at the same time. With a highly flexible system for fixing cages to the plate a wide variety of cages/bowls may be used.
A speed control enables user defined setting of the plate rotation speed depending on experimental conditions. The balance arm is equally adjustable to a wide variety of different cages/bowls.
By having the possibility of adjusting the system in a three dimensional way the most commonly used cages may be fitted to the system. A cage adapter that comes with the system is fixed to an adjustable rod and on the adapter rod the arm can be moved up and down for optimal height adjustment. The balancing arm itself can be adjusted so that it is centered in the cage.
Both systems are user adjustable within the above dimensions.
The RACS Plus has the same features as the RACS with the addition that it can also monitor the animal activity in the cage. 0ne to four sensors will keep track and register the animal movements CW and CCW. Using one sensor will monitor whole laps and four sensors will monitor quarter laps. The user may fix any of one to four sensors to the tray depending on experimental setup.
