A laboratory beaker is a versatile glass container used for mixing, stirring, heating, and holding liquids in various scientific applications. Typically cylindrical in shape with a flat bottom and a pouring spout, the beaker allows easy handling and transfer of liquids. It is commonly made from high-quality borosilicate glass, which offers excellent resistance to heat and chemicals. Beakers come with clearly marked graduations, providing approximate volume measurements, making them suitable for general laboratory use rather than precise measurement. They are widely used in chemistry, biology, and educational laboratories for routine experiments and sample preparation.
