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.

In experiments, glass rods can be used to transfer solid substances, such as removing solid reagents from reagent bottles and transferring them to other containers. The use of glass rods for transfer can prevent the loss or contamination of solid substances. Although not commonly used, in some experiments, glass rods can also be used to dip gas samples. For example, when detecting gas composition, a glass rod can be used to dip the gas and transfer it to the detection device.
