What is the main function of a beaker in a laboratory?

The main function of a beaker in a laboratory is to mix and pour liquids. Beakers are designed with a wide mouth and a spout that makes it easy to pour their contents safely and accurately. They are typically used for holding, mixing, and heating liquids, and while they can facilitate a range of laboratory tasks, their primary role is to serve as a container for these processes.

While beakers can be used for heating substances, they are not specifically designed for that purpose compared to other equipment like flasks or test tubes. Similarly, while some measuring can be done with beakers, they are not the best choice for achieving precise volume measurements, as graduated cylinders are more accurate for that task. Additionally, while titrations do involve mixing liquids, specialized equipment like burettes is preferred for that process to achieve greater control over volume delivery.

In summary, the design and function of beakers prioritize their use for mixing and pouring liquids, making them essential tools in a laboratory setting.
