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.

PlexBright Quote Request Forms (specific to the experimental set-up) are available for rapid quote return and include both the Starter Kit itemization and individual parts for selection. The forms are available on the Resources tab, as well as on the Documentation page under the PlexBright header.
