AMD-R Raturn System

BASi’s Raturn is a movement response caging system that is designed for use with tether-based applications in awake animals.  Used as an alternative to a liquid swivel or commutator, the Raturn responds to animal movement to keep wires, tubing, fluid lines and cables from twisting.

  • Reduce stress with less animal handing
  • Eliminate swivels and commutators
  • Combine multiple fluid or electrical lines
  • AMD-R systems are designed to keep pumps and collectors close to the animal minimizing dead volume
  • Use with BASi round, stackable or universal cages


The Raturn consists of a turntable and drive mechanism connected to a control box.  The rat or mouse is placed into a cage (sold separately) and tethered to a counterbalance arm.  The animal can move up to 280° before activating the optical sensor, causing the cage to counter rotate to prevent twisting.  The customizable AMD-R system includes a framed stand convenient for holding syringe pumps and fraction collectors.  The optional Raturn Activity Monitoring System easily integrates with the Raturn to observe changes in locomotor activity following treatments.  Metabolic floor inserts also available for collection of metabolic waste products.

BASI’s Raturn systems are used in academic and pharmaceutical laboratories and CROs in a wide range of applications including:

  • In vivo Microdialysis
  • Blood Collection
  • Optogenetics
  • Infusion and Biosensor Implants
  • Pressure Monitoring
  • ECG
  • Locomotor Activity Analysis
