Tungsten is a versatile and widely-used microelectrode material that offers a good balance between performance and cost.
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.
