Mätglas

A mätglas, or graduated cylinder in English, is a common piece of laboratory equipment used to measure the volume of a liquid. It is a tall, cylindrical container with markings etched or printed along its side to indicate specific volumes. These markings, known as graduations, allow for relatively precise measurements, though typically not as precise as a volumetric flask or pipette.

Mätglas are usually made of glass or plastic. Glass cylinders offer better chemical resistance and clarity, while plastic ones are more durable and less prone to breakage. The base of a mätglas is often wider than the body to provide stability, and many have a spout or lip to facilitate pouring.

When using a mätglas, it is important to place it on a level surface and read the volume at the bottom of the meniscus, which is the curved upper surface of a liquid in a tube. The accuracy of the measurement depends on the quality of the graduations and the care taken by the user. Mätglas are available in a wide range of sizes, from a few milliliters to several liters, making them suitable for various laboratory applications. They are essential tools for tasks such as preparing solutions, diluting substances, and transferring liquids when high accuracy is not the primary requirement.
