Elgiloy Microelectrodes

Elgiloy Microelectrodes

Elgiloy (a stainless cobalt-chromium alloy) is available in monopolar electrodes for specialty applications, such as vibrating probes for SVET. Elgiloy is most commonly used in dental implants and offers good biocompatibility and corrosion resistance.


ADVANTAGES


Versatile metal that offers good recording performance in acute and chronic applications.
Contains a small percentage of iron, which allows electrode tracts to be visually identified using Prussian Blue staining techniques.


DISADVANTAGES


Inadequate for microstimulation due to poor charge transfer characteristics and electrochemical instability during stimulation.
May corrode and degrade in performance when implanted for long periods of time or subjected to certain stimulation protocols.

 
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.
