Beakers are cylindrical containers with a flat bottom and an open top, typically made of glass, but can also be made of metal or plastic). They are commonly used in laboratories for various purposes, including:

• Mixing: Beakers are used to mix different liquids or solutions together).
• Heating: Beakers can be heated over a Bunsen burners flame or hot plate to facilitate chemical reactions).
• Measuring: Beakers can be used to measure the volume of liquids, although they are not as precise as graduated cylinders).
• Containment: Beakers can be used to contain a chemical reaction or catch a liquid product.
• Titration: Tall-form beakers, also known as Berzelius beakers, are mostly used for titration).

Beakers come in various sizes and shapes, including low-form beakers (Griffin beakers), tall-form beakers (Berzelius beakers), and flat beakers (crystallizers)). They can also have spouts to facilitate pouring and graduations to give an approximate indication of the volume of liquid contained. Beakers are commonly used in most chemical, biological, clinical, and industrial laboratories.
