Elgiloy Bipolar Electrodes, Heat Treated Tapered Tip
Elgiloy (a stainless cobalt-chromium alloy, similar to a stainless steel) 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.

These bipolar microelectrodes of MicroProbes are also available in Tungsten and Platinum-Iridium alloy. Each electrode is etched to a fine taper and tipped using a proprietary process to a specific impedance value. We offer a variety of different tip alternatives for those that prefer a specialized electrode profile for their research. There are four different tip profiles are also available to further fine-tune your electrode selection to your particular application. The tip selection can provide subtle yet important changes to the performance of the electrode, as described below. It is recommended that first time users consider experimenting with different tip profiles to determine which works best for their recording or stimulation protocols.
Stereotrodes are excellent for bipolar stimulation studies where the current injection needs to be confined to a small localized part of the neural tissue. They have also been used for enhanced isolation of single neural elements by simultaneous recordings of multiple units on two closely spaced microelectrodes. The tip spacing is typically equal to the diameter of the electrode shaft, however, they can be specified to greater separations in most instances.
As an alternative you may consider choosing monopolar electrodes with a thin Paryclene-C coating or with Polymide tubing for insulation, or concentric electrodes.
