Graduated cylinder

Each marked line on the graduated cylinder represents the amount of liquid that has been measured.

Large graduated cylinders are usually made of polypropylene for its excellent chemical resistance or polymethylpentene for its transparency, making them lighter and less fragile than glass.

[1] A traditional graduated cylinder is usually narrow and tall so as to increase the accuracy and precision of volume measurement.

It has a plastic or glass base (stand, foot, support) and a "spout" for easy pouring of the measured liquid.

Mixing cylinders have ground glass joints instead of a spout, so they can be closed with a stopper or connected directly with other elements of a manifold.

[2] With this kind of cylinder, the metered liquid does not pour directly, but is often removed using a Cannula.

A graduated cylinder is meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line.

[7] The main reason as to why the reading of the volume is done via meniscus is due to the nature of the liquid in a closed surrounded space.

[10] The graduated cylinder was first introduced in 1784 by Louis Bernard Guyton de Morveau, for use in volumetric analysis.
