Abstract
Iridium electrodes of very small diameter such as 35 microns are formed from larger-diameter commercially available iridium wire by an electrolytic etching process. A saturated solution of sodium chloride in a preferred etching solution. The electrodes are formed with sharp conical tips which can be rounded or blunted if desired by additional etching. Platinum lead wire is welded to the electrode shank, and the electrode is coated with an insulating varnish which is ablated at the electrode tip to expose a conductive surface.
