Volumetric Ball: uses, price, types, characteristics

November 2, 2021

As we always say, the elements that we find in the laboratory are all important, but without a doubt there are some that are more essential than others. And the reason for this is that they are totally irreplaceable. The volumetric ball falls within the range of the most important and irreplaceable. And this is because this element has been conceived in order to measure the volume of liquids with great accuracy.

What is the Graduated Ball?

The volumetric ball is an element to measure whose manufacture is in glass and whose purpose or work is to determine with perfect accuracy the volume of any liquid.

History of the Volumetric Ball

Its invention dates from the year 1861 by the chemist Emil Erlenmeyer , and is considered one of the most important achievements of physics and chemistry of all time. Undoubtedly it is a great tool, whose usefulness in scientific studies is very significant. Because it throws important data to the user.

The volumetric ball has been designed in such a way that it provides very precise results. It has an elongated neck, which has marks that are necessary to take measurements. It also contains a stopper, which can be made of plastic or cork. The cap is very necessary to avoid accidents, such as liquid spills that could be harmful to health.

What is the Graduated Ball?

The volumetric flask is also known as a volumetric flask or fiol a . It is a container or container that is generally used in physics or chemistry laboratories. The function of the volumetric balloon is to measure accurately and efficiently, without any mistake, the specific volume of liquids, it is also used to distill substances, dissolve or precipitate compounds, heat or cool liquids and it is also necessary to prepare solutions.

They are containers whose base is flat, because that way they have easy support and their neck is narrow and long with the marks that will serve to indicate the capacity that the liquid must have inside the container. These brands are also known by the name of capacity.

What are the functions of the Volumetric Ball?

Although the volumetric balloon was originally conceived only for the purpose of making precise measurements of the volume of liquids . This excellent instrument is also suitable for other types of laboratory work. For example, it is indicated to make mixtures of different types of elements and obtain a final composition. But it must be taken into account that not all measuring balls are suitable for mixing. For example, those that we find in school laboratories are basic and do not serve to perform this function.
For this important reason is that before acquiring a volumetric ball , you have total certainty of what its use will be.

Use of the Volumetric Ball

The use of the volumetric ball is really very simple , in fact the only thing you need to know is the model of the ball you need, in this way you will have an exact measure of the liquid or mixture that you require.

With the volumetric ball, quantitative data of the substance are obtained and also the behavior of said substance subjected to different temperatures. We also obtain other important data, such as the interaction of that substance that we are investigating, with other densities or substances.
The meniscus must be taken into account at the time the calculation is carried out. The meniscus is the point

center of the curve that obtains a liquid that is measured. On some occasions the edges may be lower or higher. But the most important thing is not to lose sight of the capacity. The forum is the maximum mark that a liquid reaches.

Types of Volumetric Ball

The volumetric ball is classified by color, by capacity and by precision. Although in reality we will only find two types of calibrated ball , each of them can be classified within these three categories.

According to the color

Usually the volumetric ball is made of colorless or transparent glass, there are also balls of different colors. And these are used to make mixtures with substances that are sensitive to light. Therefore, in these chaos, a colored ball is needed.

According to the volume capacity

They can be found in 1 and 2 ml, although the most common are those from 25 ml to 500 ml.

According to the precision

When we talk about precision, we find two types:
Type A:
These balls are used in the preparation of different mixtures and are also used to measure the volume of liquids. It is very common to find them in chemical laboratories.
Type B:
This type of volumetric ball is the ones that we commonly find in school laboratories and are not used for strong compositions. The requirement is much less.
All types of volumetric balloons must be properly sterilized after use.


The volumetric ball has a base in the shape of a pear or a ball and that is where its name comes from. Some of them may be plastic, but generally we find them made of glass. Its neck has a fine and elongated shape and it is where liquids are measured.

From the base of the ball to the end of its neck it has markings that allow the content to be measured. These marks are called capacity. These marks are extremely important, because it is with them that the content of the ball is measured.

The balloon also has a cap or stopper that can be made of cork or plastic. The lid is necessary, because without it the liquids could not be mixed without spilling. The lid or stopper also allows liquids to be kept inside the container. It is important to leave a space between the liquid and the lid, so that when you shake the ball they can mix.

Importance of the Volumetric Ball

The volumetric flask is an important instrument in the laboratory, especially in the chemist. You need to advance scientific research every day.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
