Microelectrode Grinders allow glass micropipettes to be beveled in order to produce sharper tips. Such tips can facilitate cell penetration in studies which require intracellular recording or injection. Microforges use a heated element to melt the glass at the end of individual microelectrodes. This procedure can be carried out to produce specialist tools for cell handling during injection or be applied gently to tips to “fire polish” them prior to patch clamping experiments. Fire polishing not only cleans and smoothes the pipette tip, but also provide a means to increase the pipette resistance.
