Concentric Electrodes

Concentric bipolar electrodes are excellent for shielded macro recording, as well as evoked potentials. They are especially well suited for bipolar stimulation. The tungsten electrode is sharpened to a point and is 75μm in diameter. The outer stainless steel conductor is insulated with Polyimide tubing to within 0.2mm of the end of the stainless steel tube. This electrode is also available without the outer Polyimide insulation. A comparison of the concentric electrodes is at the bottom of the page.
