Carbo wax is used to ensure that all electrodes are parallel which, is particularly important when deep brain structures are targeted. All of the Plextrode microwire arrays come with a ground and low-impendence reference wire which, when used with Plexon headstages and preamplifiers, assists with common-mode rejection and removal of artifacts.
The Plextrode Series of Electrodes leverages off of over 25 years of experience in electrode manufacturing and design. The microwire array is the standard choice for hundreds of research labs around the world.
- Available in any spatial configuration (2x4, 4x4, 4x8, 3x3, etc.)
- User specified wire diameter (25 µm or 50 µm) and inter-electrode spacing (250 µm or 500 µm)
- Uses carbo wax mold to fix electrode position during insertion (carbo wax is easily dissolved with saline solution)
- Arrays can be made using any Plexon-headstage-compatible Omnetics connector

Plextrode® U-Probe
The 16- and 24-channel U-Probes are now available with thinner probe diameters. The 16-channel U-Probe is now available with an outer diameter of 185 µm, and the 24-channel U-Probe is available with 210 µm outer diameter. These new U-Probes feature 15 um platinum/iridium electrode wire, which is best for resolving single units.
The U-Probe will still be available with 20 µm or 25 µm electrode wire. These thicker diameter electrode wire U-Probes are recommended for those interested in current source density analysis.
The 8-channel U-Probe is also still available. The 8-channel U-Probe is now configured with a fluid channel for drug delivery by default. The placement of this fluid capillary is user defined. These 8-channel U-Probes have an outer probe diameter of 230 µm.
