Abstract
A simplified method was used for the preparation of Pt microelectrodes sealed in glass. Electrodes were fabricated without the help of vacuum and by sealing them in soft glass capillaries. The use of SIAL and SIMAX glass produced microelectrodes with much higher and ill-defined background currents. The regular shape of voltammograms, typical for Pt, can be used as a simple test of the perfection of microelectrodes.
