Carbon microelectrodes for electrochemistry and biosensor applications

Our CFE, CDE and CDDE series carbon microelectrodes are specifically developed for electrochemical measurements such as amperometry or fast-scan cyclic voltammetry (FSCV) as well as they can provide excellent base electrodes in micro-biosensor applications. These microelectrodes are manufactured by a unique dry fabrication method so their storage and shipping over great distances are safe. The lead element carbon fibers are encapsulated in thick borosilicate glass for durable mechanical support and electrical insulation. An exceptional hermetic seal between the carbon core and the glass sheathing allows usage of these electrodes in any environment. Microelec- trodes are manufactured using two sizes and types of carbon fibers as shown on the respective data sheets.

Mating female sockets are provided for electrical connection in each shipment or use our adaptors that allow a convenient and space-saving connection to a variety of headstage amplifiers.

Custom modifications of the standard models are possible for an extra fee. Send in your sketch for a price quote 

CFE series carbon fiber microelectrodes

Part number:
CFE10100 Carbon tip: 10 μm x 100 μm (diam. x length)
CFE34200 Carbon tip: 34 μm x 200 μm (diam. x lenght)

The thick borosilicate glass sheathing makes these microelectrodes almost unbreakable. for durable mechanical support and electrical insulation. A unique hermetic seal between the carbon core and the glass sheathing allows usage of these electrodes in any environment. Microelectrodes are manufactured using two sizes and types of carbon fibers as shown in the data sheet. Standard lengths are described; other lengths are available on special orders. Mating female sockets are provided or use our adaptors M2334 for BNC-input (Dagan, npi) or M2335 for HLU-type (Axon) headstages.

CDE series carbon disc microelectrodes

Part number:
CDE 1000 10 μm diam. carbon disc
CDE 3400 34 μm diam. carbon disc

Similar to the CFE series but the tip is ground and the surface is polished at 90° on a 0.05 μm diamond particle containing surface. Other grinding angles are available on special orders. They are manufactured using two sizes and types of carbon fibers as shown on the data sheet. Mating female sockets are provided or use our adaptors M2334 for BNC-input (Dagan, npi) or M2335 for HLU-type (Axon) headstages. 

  • CDE series carbon disc microelectrodes

CDDE series double carbon disc microelectrodes (stereotrodes)

Part number:
CDDE1000 10 μm diam. carbon discs
CDDE3400 34 μm diam. carbon discs

Two parallel carbon fibers are encapsulated in one borosilicate glass sheathing then the tip is ground to form carbon discs. The active carbon disc surfaces are polished at 90° on a 0.05 μm diamond particle containing surface. Other grinding angles are available on special orders. They are manufactured using two sizes and types of car- bon fibers as shown on data sheet. Mating female sockets are provided for electrical connections.

Headstage adaptors for Kation-made carbon microelectrodes

Part number:
M2331

All Kation-made single lead element carbon fiber or tungsten microelectrodes can directly be attached to a variety of headstages using the pictured adaptors. There is no need to any additional electrode hold- er or manipulator; the microelectrode will become one piece with the headstage and they can be moved together. An additional advantage of this solution is the lack of connecting wires which may significantly improve the signal-to-noise ratio. See their combined datasheet [link to headstage adaptor page] for more information.
