Advantages
- Extremely strong and stiff metal provides probes with exceptional rigidity.
- Great for acute and chronic recording due to biocompatibility and lower cost.
- High corrosion resistance offers consistent long-term performance.
Disadvantages
- Does not provide the same degree of electrochemical performance or stability as platinum-iridium alloy, making it a poor alternative for microstimulation.
- Lower charge transfer capacity of tungsten will result in larger, potentially unsafe interfacial potentials when applying the same stimulation current as to a platinum-iridium electrode.
- Certain pH or stimulation conditions can lead to tungsten corrosion.

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. |
 |
F - EXTRA FINE TIP PROFILE Our extra-fine tip profile features a significantly sharper taper as well as a thinner insulation layer. |
