Platinum-Iridium alloy is considered by many to be the “gold standard” for chronic recording and microstimulation due to its excellent electrochemical and mechanical characteristics.
Advantages
- Pure Iridium can be electrochemically “activated” to create a layer of iridium oxide on the metal surface, imbuing it with exceptional electrochemical performance. These activated iridium oxide film (AIROF) electrodes offer some of the best stimulation performance known due to the fast faradaic charge transfer mechanisms available within the film.
- Pure Iridium is appropriate for very aggressive stimulation protocols or very small electrode sizes.
- Exceptional hardness and rigidity.
Disadvantages
- High cost due to the specialty nature of the material.
- Only available in 100 micron diameter size.
A - STANDARD TIP PROFILE
Our standard tip profile features a sharp yet robust point that offers versatile performance and an effective balance between penetration and durability.

B - BLUNTED TIP PROFILE
Our blunted electrodes are engineered to have a more rounded, bullet-shaped tip. For many applications the blunted tip can offer superior stimulation performance.

H - HEAT TREATED TAPERED TIP PROFILE
Our heat-treated electrodes are intended for those investigators who must penetrate their probes through tough membranes, such as the dura mater of larger mammals.

TIP NOT AVAILABLE
F - EXTRA FINE TIP PROFILE
Our extra-fine tip profile features a significantly sharper taper as well as a thinner insulation layer.
