History of the chemistry lab coat near me:
The blouse has long been a garment allowing workers to protect themselves from stains and dirt. Many professional branches use blouses, which are generally a solid color.
In certain sectors of activity, the color of coats varies according to the profession so that people can be easily recognized.
(For example, in the hospital, nurses’ gowns are different from those of nursing assistants or midwives so that patients can easily and quickly recognize them).
Blouses have also been worn for a long time by some housewives or formerly by schoolchildren. In the 19th century, the blouse was blue (called overalls) for workers while office managers had white coats.
The coats of the medical staff were also white because they represented hygiene. Nowadays, chemistry coats are still white. This absence of colors makes the blouse cheaper and also easier to wash. In addition, bleach stains, for example, are much less visible than on colored blouses.
- Did you know ?
Marie Curie is one of the greatest scientists of our modern era who discovered radium and who won two Nobel Prizes: one in physics and one in chemistry.
But Marie Curie is a scientist who wore a blouse for a long time that was not white while all the physicists and chemists of her time followed this tradition … But why?
Marie Curie as a scientist wore a white lab coat for a long time then changed the color of her coat on the death of her husband to signify that she was in mourning (her husband, Pierre Curie died in 1906).
Her blouse was then gray as evidenced by the photographs of the time. The garment is still on display at the museum dedicated to Marie Curie.

What is a chemistry gown made of?
The white coat is a loose white garment that allows you to perform the manipulations in practical work in chemistry and physics.
Usually the gown does not go down past the knee to be able to move well and the sleeves are long to protect the clothes and the arms.
The blouse is made with cotton fibers to be able to be washed regularly and especially to be able to be washed at high temperatures (90 ° C) to be able to remove all the stains.
The blouses are also made of cotton because it is a resistant fabric. The pockets are generally flat to avoid any risk of accident.
Finally, cotton is a material that is less likely to catch fire than other synthetic materials (made from plastics) with which many items of clothing are made.
When choosing a chemistry gown, care must be taken to ensure that the cotton density is sufficient for the gown to provide adequate protection. (You need a density of at least 200g / m2).
Why wear a chemistry blouse?
Wearing a gown during chemistry work is compulsory: at the beginning of the year the gown is one of the essential acquisitions for students who intend to pursue scientific studies.
There are several reasons why it is essential to wear a lab coat in chemistry labs.
Good to know:
The chemistry coat can also be worn during life and earth science work, where there is not as much handling of potentially dangerous products but where the handling of living products can sometimes cause many stains that are difficult to wash off.
First (and most important) reason: protect yourself from potentially dangerous projections
During practical chemistry, one is often called upon to work with chemicals that can stain or injure.
To avoid accidents, good laboratory practices should be followed. Among them, the wearing of the blouse is compulsory.
In fact, wearing a gown makes it possible to protect oneself from splashes of potentially dangerous liquids. Some reagents are very corrosive and if they come in direct contact with the skin they can cause severe injury.
- Let’s take an example : acid-base practical work: during practical work on acid-base balance, students are sometimes required to handle more or less concentrated acids and bases.
Hydrochloric acid, for example, is a solution often used in the chemical laboratory which turns out to be very corrosive and which must be handled with care.
Hydrochloric acid can destroy living tissue and can therefore cause serious injury (not to mention holes in clothing).
- Second example: practical work with silver nitrate: silver nitrate is a reagent often used in chemistry. However, if silver nitrate is not handled with sufficient care or if used with a gown, silver nitrate can cause black spots on skin (and clothing.)
Second reason: protect your clothes
The chemistry gown then helps protect your clothes. To do this, it must be closed and properly buttoned.
In practical chemistry work, we handle many products which are sometimes very messy or corrosive. Wearing a gown therefore prevents unfortunate accidents on the clothes.
Many chemical reagents are responsible for indelible stains or stains that can leave marks on fragile clothes.
Third reason: have a professional attitude
Having a professional attitude is important from high school. Wearing a gown protects against projections but also allows you to position yourself as a professional.
It makes students aware that certain professions must wear gowns to protect themselves but also to make themselves known as a specialist (gowns are also important for laboratory assistants but also for health professionals).
Some physics – chemistry or life sciences teachers also regularly wear the gown during their lessons.
The following table lists some main risks in the laboratory and the role of the gown in chemistry:
Whether it is a student or a chemistry lab student or a laboratory technician, both should follow good laboratory practices to avoid any risk of accident.
Among them, we can find the wearing of the gown but also the wearing of protective glasses, the wearing of gloves in certain cases. Long hair should also be picked up to avoid any risk.
Did you know ?
If in high school it is essential to wear a lab coat for practical work, some students, through rebellion, forgetfulness or ignorance do not want to wear a lab coat: in this case, they are generally excluded from the teacher’s practical work activities. .
The chemistry coat, essential in the laboratory.
In working life, a lab technician or chemist who refused to wear a lab coat would risk heavier penalties.
Indeed, in the event of an accident, not wearing the gown could be considered as professional misconduct according to Article L.4122Ͳ1 of the labor code: “ In accordance with the instructions given to him by the employer, under the conditions provided for in the internal regulations, it is the responsibility of each worker to take care, according to his training and according to his possibilities, of his health and safety as well as that of other people affected by his acts or omissions at work. “
Why a chemistry coat in high school and not in college?
Inevitable in high school, in college, it is extremely rare for a blouse to be requested because student manipulations have become very rare.
In fact, most of the half-groups essential for the practical work sessions have disappeared as victims of reductions in resources and have at best been replaced by “two-thirds of groups” which do not allow ideal working and safety conditions.
Moreover, if a gown was requested in the 5th grade, the rapid growth of adolescents quickly risks making it too small and unusable.
Then the physics-chemistry program of the college does not necessarily require manipulations on the part of the students, if the teacher judges that an experiment is desirable then generally it is only him who is responsible for handling the products.
To finish the last argument which pleads against the purchase of a blouse is that a good part of the pupils will orient themselves at the end of the third towards a professional path where this one is no longer useful.
