Graduated cylinders are handy for accurate measurements of small volumes of liquid that cannot be done with beakers and flasks. Borosilicate glass has the advantage over other materials such as polypropylene and TPX if you are going to use oxidizing materials and certain hydrocarbons which can cause the plastic to cloud.
Graduated cylinders are made to ISO 4788 and are accurate to 1.0% of full scale.
