Carnoy Liquid

Carnoy's liquid is a microbiological research liquid used for fixing and staining microorganisms. It was invented by Belgian microbiologist Jean Baptiste Carnoy in 1884 and named after him.

Carnoy liquid is a mixture of carbolic acid (phenol) and ethanol in certain proportions. Ethanol is used to dissolve carbolic acid to make it more accessible to bacteria and other microorganisms. Carbolic acid is a strong disinfectant that kills most bacteria and viruses and also has antimicrobial properties.

The use of Carnoy fluid allows microbiologists to observe microorganisms in their natural habitat, allowing them to better understand their behavior and function. In addition, Carnoy fluid can be used to isolate pure cultures of microorganisms, which can then be studied in the laboratory.

However, Carnoy liquid has a number of disadvantages. First, it is toxic if inhaled or comes into contact with skin, so precautions must be taken when handling it. Secondly, with prolonged use, carnoy liquid can cause skin and eye irritation, and can also be carcinogenic if ingested. Therefore, when working with Carnoy liquid, it is necessary to use protective equipment and avoid contact with skin and eyes.

Overall, Carnois fluid is an important tool for microbiology and can be used to study various microorganisms such as bacteria, viruses and fungi. However, when working with this liquid, you must be careful and use protective equipment to avoid possible negative consequences.



Carnoy is a name that emerged during many years of development in the science of bacteria. The liquid was named after the Belgian microbiologist Georges Vasnel Carnouail, who was the first to study this product. In addition, Carnuaia was one of the first scientists to use microscopy to study bacteria, which became a powerful tool in his research.

Carnoy's liquid is a mixture of two bacteria: group A streptococcus and micrococcus lividum. This combination was identified in 1887 by bacteriologists of the Belgian State Agricultural Service. It also contains small amounts of lactobacilli and yeast.

This product is popular among farmers and is an effective remedy for combating various bacterial infections. It is used as a bactericidal agent in animal husbandry and horticulture. Carnuau is also used to produce various drugs such as penicillin and eumycin, as well as in the food industry.

Carnuau's study of liquid is associated with the names of many microbiologists, including Georges Wassnel Carnoy, Georges Banazel, Cornelius van Gehukrten and many others. Its use in agriculture promotes the growth of many crops, but now has problems with the negative consequences of overuse.

In addition to this, Carnoy can be used to disinfect skin and mucous membranes, which can prevent the spread of infections in healthcare settings.
