What Are Graduated Cylinders?
Graduated cylinders are pieces of scientific equipment which are used for volume measurements of liquids. In addition to being used to measure liquid volume, they can also be used in density measurements for certain types of objects, which can be lowered into a graduated cylinder filled with water or another fluid to see how much fluid is displaced by the object. Many manufacturers of scientific equipment make graduated cylinders, and they are readily available at science supply stores, through catalogs, and at online merchants who sell lab equipment.
