what is a graduated cylinder

A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape and is marked with horizontal lines to represent units of measurement. The primary use of graduated cylinders is measuring liquids, and they are generally more accurate and precise than laboratory flasks and beakers. Graduated cylinders are meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line. They are available in various sizes, typically ranging from 10 mL to 1000 mL, and are not intended for mixing, stirring, heating, or weighing.
