Carbon Microelectrodes

Carbon Microelectrodes Glass-insulated

Carbon fiber microelectrode isolated by glass. The electroactive diameter is 4.7 μm, the RG value approximately 3, and the length approximately 8 cm.

The carbon fiber is embedded directly in glass and the surface is polished as a micro disc. No polymers and no glues are used in order to isolate the core of the carbon fiber. Therefore the electrodes can be used in agressive chemical media like acids and organic solvents (methylene chloride, acetonitrile).

The RG value is the ratio of the total tip radius over the radius of the electroactive disk. The electrode can be connected to a preamplifier with a HEKA Microelectrode Holder (d=2.0 mm).
