Cluster Microelectrodes

Cluster Microelectrodes are widely used for recording or stimulation in chronic applications. We offer recording/stimulation sites in stereo arrangements up to bundles of 6 and beyond. We can custom offset the sites for depth studies, or provide a center reference microelectrode surrounded by a bundle of recording sites for differential recording.

For Research Only – Not For Human Use

These cluster microelectrodes are designed for acute research and can be used to stimulate a single cell.

Detailed specifications and technical information can be found under the Technical Documents tab.

Sold in packages of 3.
