Uses

• Stirring solutions: Glass rods are primarily used to stir mixtures or solutions, ensuring even distribution of solutes.
• Decanting liquids: When pouring liquids from one container to another, the glass rod helps guide the liquid along its surface to prevent splashing.
• Spreading liquids: In microbiology labs, glass rods (specifically bent into a “hockey stick” shape) are used to spread cultures on agar plates.
• Inducing crystallization: A glass rod can be used to scratch the inside of a container, inducing crystallization in supersaturated solutions.
• Testing for acidity: Glass rods can be used to transfer small drops of liquid onto pH indicator papers for acidity testing.
