Overview

The Carbon Fiber Electrodes (CFE-2) from ALA Scientificare the ideal electrodes for voltammetric and amperometric studies. They are critical for identifying and determining the kinetics of released neurotransmitters. The CFE-2’s are made through parylene coating of paint which creates the highly sensitive environment for the detection of these small signals of interest. CFE-2’s  are sold in packs of 10.

Key features of CFE-2’s include:

  • 5μm OD carbon fibers for recording from small cells
  • Multiple re-uses due to easy re-cutting of tip
  • Slim design for use with water-immersion objectives

Details

Carbon Fiber Electrodes (CFE-2) from ALA Scientific  are safe and durable. Each tip is left extra long so that you can decide how short to cut it. Each tip can be cut back at least ten times. Each cut reveals a fresh 5μm OD carbon disk that is clean and ready for the next ReDox. The glass outer coating of the electrode body provides a strong mechanical support that is resistant to movement from temperature fluctuations. Other electrodes insulated with plastics can drift as temperatures change. In addition, glass does not absorb water, a factor that can induce noise, as much as polypropylene does. Each CFE-2 is also insulated with Sylgard, just like a patch electrode, to provide lower noise.

Coating of the CFE-2’s is done with Parylene. We can also fabricate carbon fiber electrodes with your own carbon fibers – please call or email to inquire.
