A graduated cylinder is a standard piece of laboratory glassware used to measure the volume of an object or amount of liquid. As its name indicates, it is a glass cylinder with marks along the side similar to those on a measuring cup. The volume is read by looking at the top of the fluid from the side and reading the mark on the glass from the lowest portion of the lens-like meniscus of the liquid.
These types of cylinders are specifically designed to make accurate volume measurements. By taking a reading before inserting an object in the cylinder and then after inserting it, one can tell the volume of the object from the difference of the two readings and subsequently calculate its density.
Difference between a beaker and a graduated cylinder: According to Indigo Instruments, the accuracy of a beaker is about 10 percent. A graduated cylinder is accurate to 1 percent of its full scale. Graduated cylinders have a smaller width than beakers. This is why a beaker is better for stirring and mixing liquids.
