IDsorter for rats

IDsorter for rats - side view

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.

An integrated weighing scale allows the continuous monitoring of the animals’ health conditions.

  • Based on RFID-technology
  • Integrated weighing scale
  • 24/7 operant experimentation and observation system
  • Compatible with operant boxes or mazes from third party vendors
  • Animal friendly gates with position detectors preventing accidental entrapment
  • Reduced stress for the animals (no manual handling)

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.

  • Combining group living with testing arenas
  • Fully automated 24/7 experimentation for individual operant procedures
  • Long term observation of the individual weight – monitoring of animal well being
  • High-throughput phenotyping
  • Compatible with TouchscreenChamber
