Description:

The Model MMGC-l is specifically designed for glass coating metal microelectrodes. The device has a platinum band heating element with its center formed into an omega type U shape where a glass bead is placed and heated to the proper molten consistency. The heater control knob provides the adjustment required to achieve this. The electrode is placed and held by a hypodermic needle. The y-axis is then set so that the electrode is in front of the heating element and molten glass. The x-axi 5 then centers the electrode to the glass. While viewing through the microscope, the z-axis is then adjusted vertically so that they-axis can back the electrode into the glass with just the right amount of tip exposed out of the bottom of the glass. When the fine z-axis adjustment is achieved leaving just the proper tip exposed, the electrode is then driven straight downward to coat the length of the electrode shaft. The y-axis adjustment then takes the electrode back out of the glass and the electrode is removed.
