Abstract
Method for making an electrode having an axial capillary bore with an intersecting bore. An extensible tube is inserted in the axial bore and a polymerizable mixture is inserted in the intersecting bore and permitted to polymerize against the tube which is stretched to facilitate removal of the tube. The tube is selected to swell under the action of the solvent and the tube is filled with solvent.
