Graduated cylinder

''Graduated cylinder

A graduated cylinder is a kind of laboratory glassware that is used for measuring the volumes of liquids in a semiquantitative manner. They consist of a long cylindrical tube, much taller than they are wide, with markings on the side to denote volumes. The top usually has a small curled lip to allow easy pouring of liquids, and the bottom is usually anchored with a wide base, to keep the cylinder from easily tipping. The volumes of liquids graduated cylinders can handle ranges from a few milliliters to many liters.

The tendency is for the largest graduated cylinders to be made of plastic, to make them lighter and more break resistant. But otherwise, they can be made of plastic or glass or Pyrex ®, if need be.
