A beaker is a simple, cylindrical container used in laboratories for mixing, heating, and measuring liquids. Made from glass or plastic, beakers often have a spout for easy pouring and are marked with measurement lines to help scientists accurately gauge the volume of liquids. They come in various sizes, making them versatile tools for experiments. In addition to their use in science, beakers are also popular in educational settings, where students learn about chemistry and physics. They can be found in many science labs, and their design allows for easy observation of reactions, making them essential for both professional and educational purposes.
