NEW PlexBright Dual LED + Fluid Swivel Commutator

The PlexBright Dual LED + Fluid Swivel is also ideal for experiments in which optogenetic stimulation is performed simultaneously with drug perfusion.

This commutator is designed to be used with the PlexBright Head-Mounted LEDs. It also has a removable torque arm that can be used to help transfer torque from the animal to the commutator.

  • Perform simultaneous optic stimulation and intravenous drug delivery, or perfusate delivery for microdialysis or voltammetry
  • Compatible with up to two of our new high-power Head-Mounted LEDs and our PlexBright LD-1 and 4 Channel Optogenetic Controllers

The table below provides many of the most commonly requested specifications.
