The glass rod can also serve as a support for other experimental tools. For example, in titration experiments, a glass rod can be inserted into a burette to fix its position, facilitating the experiment. In electrolysis experiments, glass rods can play a conductive role. By connecting the power supply and electrodes, the glass rod can transmit current and promote the electrolysis reaction.

Glass rods come in various shapes, including straight rods, curved rods, and stirring rods. These glass rods of different shapes play their unique functions in the laboratory. The straight glass rod is the most common type, mainly used for stirring solutions, transferring solid substances, and serving as a support for tools such as burettes. The differences in length and diameter also result in different applications in different experiments.
