IDsorter

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 to a test arena, this process is fully automated. Our system can be interfaced to operant systems from other vendors or to video observation systems.

  • Based on RFID-technology
  • 24/7 operant experimentation and observation system
  • Compatible with operant boxes or mazes from third party vendors
  • Reduced stress for the animals (no manual handling)

RFID Technology

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
  • High-throughput phenotyping.
Operating voltage 100-240 V AC
Output voltage 12 V AC
Output current 1 A
  • Two sizes available: IDsorter Mouse and IDsorter Rat
  • Automated body mass measurement with integrated electronic balance
  • Can be combined with our Touchscreen Chamber.

IDsorter with 3 transponder readers and double-door system. A balance is optional.

Mode of Operation

  1. An animal is detected at RFID-Reader 1. If the experimental protocol gives permission, gate 1 opens.
  2. The animal is detected at RFID-Reader 3. Gate 1 closes. Gates 1 and 2 remain closed for 30s.
  3. After 30s, gate 2 opens. The animal can enter the operant compartment. Gate 2 closes if the animal is registered within the operant compartment.
