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.

When transferring or filtering solutions, glass rods can serve as drainage devices. For example, in a filtration experiment, using a glass rod to drain the liquid to be filtered into a funnel can prevent liquid splashing and accelerate the filtration speed. A glass rod can be dipped into a solution to detect its acidity or alkalinity, or a small amount of solution can be used for other experiments. When dipping into the solution, it is necessary to keep the glass rod clean to avoid contaminating the solution.
