Abstract

A replaceable tip for a rotating disk electrode is shown in Fig. 1. The tip has a disk 12, for example, platinum or glassy carbon, that is sealed in glass 14. Electrode disks 12 of other materials, such as Ag, Au, Cu, Ni, etc., can be made by plating, evaporating or sputtering these metals onto a Pt or carbon disk. This system provides a leakproof seal. The tip screws onto a rotating spindle by means of the interior threads 10. An alternate embodiment is shown in Fig. 2 including a TEFLON* insert 16 that has its inside surface 18 threaded to receive the spindle (not shown). * Trademark of E. I. du Pont de Nemours & Co.
