A tungsten electrode insulated by a concentric arrangement of glass-pipettes for iontophoresis.

U Sonnhof, D W Richter, R Steinberg.   

Abstract

A method is described by which electrolytically sharpened tungsten wires were coated with a coaxial assembly of 5-8 glass-capillaries. This glass coating provides good insulation and high rigidity of the tungsten electrodes. The glass pipettes were used for electrophoretic ejection of test substances and the tungsten electrode for extracellular recording of neuronal activity.
