Beakers are cylindrical in shape, with a notch on one side of the top for easy pouring of liquids. Because the beaker has a consistent opening from top to bottom, it is very convenient for accessing liquids. It is the most commonly used reaction vessel for simple chemical reactions. During use, beakers often require a beaker stand to place and monitor the beaker.
