A graduated cylinder is a piece of laboratory equipment
Laboratory equipment

Laboratory equipment refers to the various tools and equipment used by scientists working in a laboratory. These include tools such as Bunsen burners, and microscopes as well as specialty equipment such as operant conditioning chambers, spectrophotometers and calorimeters....
 used to accurately measure out volumes of objects for use in labs. They are generally more accurate and precise for this purpose than flasks and beakers. Often, the largest graduated cylinders are made of polypropylene
Polypropylene

Polypropylene or polypropene is a thermoplastic polymer, made by the chemical industry and used in a wide variety of applications, including packaging, textiles , stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes....
 for its excellent chemical resistance or polymethylpentene
Polymethylpentene

Polymethylpentene or TPX is a thermoplastic polymer of methylpentene monomer units. It is used for gas permeable packaging, autoclave medical and laboratory equipment, microwave components, and cookware....
 for its clarity, making them lighter to ship and less fragile than glass. Polypropylene cylinders have excellent chemical resistance and do not shatter when dropped, one problem with this type of cylinder is that they can not be heated.

 for its clarity, making them lighter to ship and less fragile than glass. Polypropylene cylinders have excellent chemical resistance and do not shatter when dropped, one problem with this type of cylinder is that they can not be heated. Polypropylene is easy to repeatedly autoclave (sterilize); however, autoclaving of some polypropylene graduated cylinders may affect their accuracy (check with the manufacturer). They are often used for collecting and recording a volume of gas given off in a reaction.
