a cylindrical container with volume markings used to measure the volume of liquids
A graduated cylinder is a tall, narrow container used to measure the volume of liquids accurately. It is made of glass or plastic and has markings along the side, indicating different measurements. These markings allow one to read the exact amount of liquid inside. Graduated cylinders are commonly used in laboratories for precise liquid measurements in experiments or when mixing substances. They are typically more accurate than beakers or flasks due to their narrow shape, which reduces the risk of error when reading the liquid level.
