What Is a Measuring Cylinder?

A measuring cylinder, also known as a graduated cylinder, is a tall, narrow laboratory vessel designed for accurate liquid volume measurement. Its cylindrical shape and clearly marked graduations provide greater precision than a standard beaker, making it ideal for quantitative experiments in school and professional laboratories.

Measuring cylinders are widely used in chemistry, physics, and biology for preparing solutions, conducting dilution experiments, calculating density, and measuring displaced water volume. Their stable base and readable scale markings allow students to work safely and confidently during practical investigations.

Materials and Construction

Measuring cylinders are commonly manufactured from borosilicate glass, polypropylene, or TPX (polymethylpentene). Borosilicate glass cylinders provide excellent chemical resistance and durability for laboratory use and are available in a full range from 5ml to 2000ml. Polypropylene cylinders offer lightweight, impact-resistant performance for general classroom environments, while TPX cylinders combine high transparency with improved heat resistance.

All material types are designed with clearly defined graduation marks to ensure reliable volume readings when measurements are taken at eye level at the bottom of the meniscus.

Accuracy and Graduation Marks

The narrow design of a measuring cylinder reduces surface area and improves measurement accuracy compared to wider vessels. Graduation lines indicate volume increments, and for best results, readings should always be taken at eye level to minimise parallax error.

When precise measurement is required, a measuring cylinder is generally preferred over a beaker due to its improved scale definition and reduced measurement variance.

Common Measuring Cylinder Sizes in Schools

5ml and 10ml glass measuring cylinders are ideal for small-volume precision work and introductory science activities. 100ml and 250ml cylinders are the most widely used sizes in secondary school laboratories, supporting a broad range of chemistry and physics practicals. Larger glass capacities such as 500ml, 1000ml, and 2000ml cylinders are suited to advanced experiments, bulk solution preparation, and higher-volume measurement requirements.

Plastic and TPX measuring cylinders are commonly selected for general classroom use where durability and impact resistance are prioritised.

Frequently Asked Questions

What is the difference between a measuring cylinder and a beaker?
A measuring cylinder is designed specifically for accurate volume measurement, whereas a beaker is better suited for mixing, heating, and general handling of liquids.

Are glass measuring cylinders more accurate than plastic?
Glass measuring cylinders are often preferred for higher precision laboratory work, while polypropylene and TPX cylinders provide excellent durability and safety in classroom environments.

What is another name for a measuring cylinder?
A measuring cylinder is also commonly referred to as a graduated cylinder.
