What is a beaker used for
A beaker is a cylindrical glass container with a flat bottom and a pouring spout. It is used for holding and measuring liquid volumes in laboratory settings. Beakers are commonly used for mixing, heating, and observing chemical reactions. They are also used for storing and transferring liquids.
A beaker is a common laboratory glassware used for holding, mixing, and heating liquids. Some of its main uses include:
1. Holding and measuring liquids: Beakers are commonly used to hold various liquids in the laboratory, such as water, chemicals, solvents, or samples.
2. Mixing and diluting solutions: Beakers are ideal for mixing solutions of different substances, as they have a wide base and a pouring spout, allowing for easy mixing and transferring of liquids.
3. Heating substances: Beakers are heat-resistant and can be placed directly on a hot plate or over a Bunsen burner flame for heating substances. They are commonly used for processes like boiling, evaporating, or heating liquids.
4. Observation: Beakers are often used for making qualitative observations, such as examining the appearance or color changes of a reaction or conducting simple experiments.
It is important to note that beakers are not typically used for precise measurements, as they are not designed with calibrated markings for accurate volume readings. For precise measurements, instruments like graduated cylinders or burettes are preferred.
