- Stainless Steel Metal Micro Electrodes
The stainless steel (Elgiloy) electrodes are widely used as the primary component for the ‘vibrating probe’ electrode. It is vibrated at a fairly high frequency and is used to record very small DC potentials. It is also use for Prussian blue staining around the tip by passing a small anodal current.
- Outstanding for extracellular recording and micro-stimulation
- Unique, precision manufacturing process provides consistent repeatable tip profiles for superior performance
- Select from 4 metals, 3 styles, and 4 tip profiles to meet almost any application
- Gold-plated connector pins for superior electrical connections
- Custom made probes readily available
Available with Parylene-C insulation on the metal shaft. All of the microelectrodes are sharpened electrochemically and their tips are individually exposed under a microscope. Each is inspected to assure reproducible tip exposures and profile.
- Tungsten Metal Micro Electrodes
These tungsten metal micro electrodes are ideal for a multitude of applications including single- and multi-unit studies, stimulation, lesioning, and evoked response studies. Tungsten is the most versatile and widely used type of probe. It is ideal for demanding recording situations and most stimulation protocols.

Available in three styles:
- Standard style with 3 mm or 1 mm of Parylene-C insulation on the metal shaft.
- Standard style with the addition of polymide tubing on the shaft which provides additional reinforcement for easy electrode insertion. The additional insulation also minimizes signal attenuation making this an ideal electrode for deep brain penetrations.
- Stereotrode/Biopolar style for micro bipolar stimulation. These electrodes are ideal where the current injection needs to be confined to a small, localized part of the nervous system. They are also used for enhanced isolation of single neural elements by simultaneously recording from multiple units of two closely spaced microelectrodes.
- Iridium (Pure) Metal Micro Electrodes
The pure iridium Electrodes are ideal for improved stimulation and recording. Pure Iridium is extremely stiff and has a much lower concomitant tip impedance than any other noble metal. It is extremely inert and very resistant to corrosion. Consequently, it is much less likely to erode during stimulation and can be activated using cyclic voltametery for increased charge storage capacity to lower tip impedance values.Available with the addition of polymide tubing on the shaft which provides additional reinforcement for easy electrode insertion. The additional insulation also minimizes signal attenuation making this an ideal electrode for deep brain penetrations.All of the microelectrodes are sharpened electrochemically and their tips are individually exposed under a microscope. Each is inspected to assure reproducible tip exposures and profile.
- Platinum/Iridium Metal Micro Electrodes
The platinum/iridium mix electrodes have a lower concomitant impedance value than tungsten or stainless steel for the same exposure, therefore they are ideal for recording. They are also superior for stimulation studies because they are less likely to erode during intense stimulation protocols. This metal mixture is also excellent for chronic implants because it is very biocompatible. Available in two styles: Standard style with 3 mm or 1 mm of Parylene-C insulation on the metal shaft. Standard style with the addition of polymide tubing on the shaft which provides additional reinforcement for easy electrode insertion. The additional insulation also minimizes signal attenuation making this an ideal electrode for deep brain penetrations. All of the microelectrodes are sharpened electrochemically and their tips are individually exposed under a microscope. Each is inspected to assure reproducible tip exposures and profile.
- Stainless Steel Metal Macro Electrodes
These stainless steel metal macro electrodes are similar in construction to our metal micro electrodes except they are larger in size. They are excellent for stimulation, lesions, and recording evoked responses.
Tungsten Metal Macro Electrodes
These tungsten metal macro electrodes are similar in construction to our metal micro electrodes except they are larger in size. Their shaft diameters range from 0.009 inches (229 µm) to 0.02 inches (508 µm).
