A measuring cylinder with a pentagonal shape made of polypropylene (PP) is a laboratory apparatus used for measuring the volume of liquids. The cylinder is marked with graduated markings on the side which indicate the volume of the liquid contained in the cylinder.

The pentagonal shape of the measuring cylinder provides stability and prevents the cylinder from rolling, making it easier to use. Measuring cylinders are commonly used in laboratory settings for tasks such as dispensing reagents, measuring volumes of liquids, or mixing solutions.

The use of a PP material makes the measuring cylinder durable, lightweight, and resistant to chemicals commonly used in the laboratory. Additionally, polypropylene is chemically resistant and can be used with a wide range of liquids without the risk of contamination or corrosion.
