What is methylene blue?

Methylene blue is a synthetic dye with the chemical formula C₁₆H₁₈ClN₃S. Due to its intense blue color and chemical properties, it has been used for many years in laboratories, research institutions, and educational establishments.

Methylene blue is particularly well known as a staining reagent for microscopic examinations. By staining biological structures, cells and tissues can be made much more visible.

The Methylene blue solution 0.1% available at BIOLABORATORIUM is offered as a ready-to-use aqueous solution and is suitable for professional laboratory applications.

Important properties of methylene blue

Methylene blue is valued primarily for its staining and analytical properties.

The most important features include:

• intense blue coloration
• good visibility under the microscope
• Use as indicator dye
• high purity
• versatile use in lab and research

Technical data of the solution:

• Concentration: 0.1%
• Dye content: at least 96%
• Molar mass: 319.88 g/mol
• CAS number: 61-73-4
• EC number: 200-515-2

Methylene blue in microscopy

One of the most important applications of methylene blue is microscopy.

Many biological structures are difficult to see without staining. Targeted staining makes cell nuclei, tissue samples, and other microscopic structures much more visible.

Typical areas of use are:

• Education and teaching
• biological examinations
• histological preparations
• microscopic demonstrations

The intense staining facilitates the evaluation and documentation of specimens.

Applications in microbiology

Methylene blue also plays an important role in microbiology.

Here, the dye is used, among other things, to make microorganisms visible or to support certain test procedures.

Possible areas of application:

• bacterial staining
• Differentiation of microorganisms
• Laboratory tests
• microbiological training purposes

The good visibility of stained structures makes methylene blue an established aid in microbiological laboratories.

Significance for research and laboratory analytics

In addition to microscopy and microbiology, methylene blue is also used in various research and analysis procedures.

In scientific laboratories, the dye serves, for example, as:

• Indicator dye
• Auxiliary substance in analytical procedures
• Reagent for laboratory analyses
• Component of experimental setups

The versatile properties make methylene blue a commonly used laboratory reagent in research institutions and universities.

Which container sizes are available?

Depending on the area of application, different quantities are needed.

At BIOLABORATORIUM, the Methylene Blue Solution 0.1% is available in several container sizes:

• 100 ml
• 500 ml
