Graduated cylinder
A graduated cylinder is a common laboratory instrument used to measure the volume of liquids accurately. It is a tall, narrow container made of glass or plastic, marked with precise measurement lines (graduations) along its side. By pouring a liquid into the cylinder and reading the level at eye height, users can determine the exact amount of liquid present. Graduated cylinders are ideal for experiments requiring precise volume measurements, and their design helps minimize errors associated with reading liquid levels. They are essential tools in science labs, medical environments, and various industrial applications.
