It should be noted that when using glass rods, it is necessary to follow laboratory safety regulations to avoid glass rod breakage or skin scratches. At the same time, the glass rod after use should be cleaned in a timely manner and placed back in the designated position to maintain the cleanliness and order of the laboratory.

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.
