Laboratory Brush: characteristics, prices, uses, types …

November 2, 2021

Test tubes, flasks, and other glass devices need special cleaning, mostly after use. And to clean them properly you must use a laboratory brush .
The laboratory brush is the brush that is used to clean test tubes among other devices that we find in the laboratory.

It is a brush generally made of nylon fiber bristles. But we can also find it made of other elements such as synthetic or animal skins of various sizes. These bristles are aligned and fastened to a somewhat sturdy wire handle and at one end it has loops or waves that allow it to be hung.

The wire handle is metal. Some are beryllium, bronze, brass, or copper. Its design has been thought so that it can be used in the cleaning of long and somewhat thin tubes. But they also resist contact with corrosive chemicals and acids.

Laboratory Brushes Measurements

The laboratory brush or brush for cleaning tubes has various measures. We find them from 10mm to 2000mm (length) and from 3mm to 200mm (diameter).

These brushes have been designed for the purpose or purpose of cleaning test tubes. And for that reason is that several measures have been developed, so that the brush can thoroughly clean the glass tubes.

Types of Laboratory Brushes

Radical tip brush with steel stem. They are similar to radical tip brushes, only they have a longer life.

Brush or brush with radical tip. The rounded tip of the tube allows the edge of the brush to be curved. Protects the glass from contact with the metal handle.

Sponge tip brush. It is a soft tip that allows the absorption and expansion of the liquid. This allows for a thorough cleaning of the tube and protects it from scratches and scratches.

Brush or brush with bonded tip. In this type of brushes or laboratory brushes, the bristles are attached or tied together at the tip. This facilitates the cleaning of the tube (s). It also cleans bottles or any other container that has a small “mouth” or opening. The glass surface expands inside the tube without scratches.

What is the laboratory brush used for?

The main function of the laboratory brush is to clean the interior of the different instruments that we find in a laboratory. The cleaning and cleaning of the instruments is done after some practice is done.

Laboratory instruments that can be cleaned with the brushes are:

Importance of the Laboratory Brush or Brush

The brushes laboratory are considered essential in any laboratory. Thanks to the brushes or brushes it is possible to maintain the perfect and recommended hygiene of each of the instruments used in the research area, therefore, the brush is an element that cannot be missing.

The instruments that we find in the laboratory are, without a doubt, the most necessary and important materials for the preparation of medical and chemical studies or analysis of any substance.

These implements must be made with the best materials, for the reason that they can withstand each of the processes that are carried out in the laboratory, therefore you must make sure that the tools you use are of the best and highest quality.

More about the lab brush

This device used in laboratories, that is, the brush or brush is designed to clean surfaces that access to clean is very difficult, or impossible. To give a good example, pieces of small dimensions. Thanks to the laboratory brush you can reach all the interior walls of test tubes, test tubes, etc. Artifacts with more inaccessible backgrounds.

Among the laboratory instruments used for cleaning with the brush are: glass cylinders, test tubes, burettes, beakers, pipettes, flasks or any glass or crystal bottle found within the laboratory.

One of the most common processes that are most carried out in a laboratory is the cleaning of tools, in order to be able to keep them in the best conditions to carry out studies or experiments. Therefore, it is necessary to give the right importance to the use of the brush or laboratory brush. It is as or perhaps more important than any other instrument we find within the laboratory.

How to clean and sterilize instruments in the laboratory

Proper cleaning and disinfection of all instruments within the laboratory is very important. The materials must be sterilized because if they were not properly sterilized, it could have too serious consequences, both at a health and economic level.

Similar is not the same – Let’s see the importance of certain concepts


It consists of the first action within a laboratory. It is carried out with filtered drinking water, mild detergents and in the event that certain products that have adhered to the objects used for laboratory work have to be removed, other products that are more suitable for removing said adhesions are used.


It is another type of cleaning, much deeper, because it aims to reduce the microbial and bacterial population of the material used in the laboratory. The most common disinfectant is chlorine, and it is the one we use in the laboratory.


Sterilization consists of another much more “advanced” phase of cleaning. Items are kept in a “sterile phase” until new use. Then, after or after disinfection, any microorganisms that cause infections are eradicated. And for this we are going to sterilize the laboratory instruments.


Asepsis is the prevention of infections by destroying contaminants and to do so, antiseptic agents or products are used that are responsible for preventing the growth of microorganisms in the laboratory and its instruments.

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.
