Matrix Microelectrodes

Matrix Microelectrodes combine our Metal Microelectrodes into one assembly that is completely tailored to the user’s application. We are able to produce matrix microelectrodes from a 2×1 bipolar stimulating version to a 144 (or beyond) mapping grid.

These microelectrodes have a length of 50mm and have a parallel configuration using 2 microelectrodes for Invitro and Invivo Cortical mapping single and multi-cell recording and stimulation.

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

Sold in packages of 3. Tungsten 30255 and 30256 are sold in packages of 12.
