Volumetric glassware or volumetric flasks are containers that have been calibrated to a specific volume. These flasks, unlike Erlinmeyer flasks or beakers, are marked with lines that are calibrated to a specific volume of liquid. A volumetric flask should be used whenever an accurate concentration of solution is required.

Graduated Cylinders are volumetric measuring devices designed to measure and deliver accurate volumes of liquids.

meniscus

When measuring liquids in a graduated cylinder, you always measure from the center of the curvature in the liquid called the meniscus. Some liquids, like mercury, have a convex meniscus. Most liquids, however, will have a concave meniscus and the volume in the graduated cylinder should be read from the bottom center of this meniscus (as above).
