It is beneficial for animals to live in groups rather than in single housing. Many behavioural diagnostic tests, however, require an individual animal to be alone while tested. Traditionally, this requires manually placing an animal from a home cage to the test arena and back. With the IDsorter connecting the home cage with a test arena, this process is fully automated. Our system can be interfaced to operant systems from other vendors or to video observation systems.
Check out this video to see how it works.
The larger version for rats can be found here.
The IDsorter is based on RFID-technology. It allows the selective passage of a single animal to the test arena and back, while individual experiments can be conducted in the operant chamber with independent experimental control software.
Radio-frequency identification (RFID) technology identifies and tracks an individual within a group of animals. All animals need to carry subcutaneous transponders. These transponders require no battery and are powered by the electro-magnetic fields emitted by the RFID-Readers.
