In biological experiments, electrodes are usually precisely inserted into cells. The electrodes are usually drawn from glass tubes, and microelectrode drawing instruments are commonly used tools to draw glass tubes into electrodes. The basic principle is to place the glass tube in a heating wire and control the temperature of the heating wire to burn the glass tube. While heating the glass tube, a certain tension is applied to both ends of the glass tube to draw it into various required electrodes for the experiment.
