Iridium (Pure) Metal Micro Electrodes

Price on Request

The pure iridium Electrodes are ideal for improved stimulation and recording. Pure Iridium is extremely stiff and has a much lower concomitant tip impedance than any other noble metal. It is extremely inert and very resistant to corrosion. Consequently, it is much less likely to erode during stimulation and can be activated using cyclic voltametery for increased charge storage capacity to lower tip impedance values.

Available with the addition of polymide tubing on the shaft which provides additional reinforcement for easy electrode insertion. The additional insulation also minimizes signal attenuation making this an ideal electrode for deep brain penetrations.

All of the microelectrodes are sharpened electrochemically and their tips are individually exposed under a microscope. Each is inspected to assure reproducible tip exposures and profile.
