Tunglass-2 tungsten microelectrodes with glass insulation of extreme durability
W2011S Standard tip,
W2011F Fine tip
W2011EF Extra-fine tip
Manufactured by proprietary method, this glass insulated tungsten microelectrode represents a truly exceptional solution to many drawbacks associated with more traditional metal microelectrodes.
The industry standard gold-plated pin on top allows a low-resistance galvanic connection to most headstage probes. The 1.5 mm outer diameter borosilicate glass sheathing provides an additional support for the fine tungsten wire and allows a convenient way to handle and to attach this microelectrode to any holder.
Next to the holder section, the glass forms a 40 to 80 micrometer thick electrically insulating layer sturdily adhering to the lead element tungsten wire for about a length of 35 mm. Finally, the glass insulation tapers onto the tungsten tip, etched to standard, fine or extra-fine profile.
