Methylene Blue 2 % for laboratory and technical use • aqueous solution • independently laboratory tested • amber glass bottle with dropper • 100 ml
WoldoHealth Methylene Blue 2% is an aqueous solution of methylthioninium chloride at a concentration of up to 2%, intended for laboratory, analytical, technical and research use. It is supplied in a 100 ml bottle with a dropper for controlled application.
The higher 2% concentration is suited to procedures that require a more concentrated stock solution or subsequent dilution in accordance with a specific laboratory protocol. This product is not intended for internal use, direct consumption, or use as a food supplement or medicinal product.
Important: for laboratory and technical use only. Protect the skin, eyes, clothing and work surfaces during handling, as methylene blue is a highly intensive dye.
What is Methylene Blue 2%?
WoldoHealth Methylene Blue 2% is an aqueous solution containing methylthioninium chloride, also known as methylene blue, at a concentration of up to 2%. The substance is identified by CAS number 61-73-4.
The product is intended exclusively for laboratory, analytical, technical and research use. It is supplied as a ready-to-use solution in a 100 ml bottle, removing the need to prepare a solution from powdered material before routine laboratory use.
Important notice: this product is not intended for internal use, direct consumption, or use as a food supplement or medicinal product.
Key features of Methylene Blue 2%
- Aqueous methylthioninium chloride solution.
- Concentration of up to 2%.
- Chemical identifier CAS 61-73-4.
- Volume: 100 ml.
- Intended for laboratory and technical use.
- Ready-to-use liquid solution.
- Bottle with dropper for controlled application.
- Store in a dry, dark place at temperatures up to 25 °C.

What is the product intended for?
Methylene blue is used in laboratory settings as an intense blue dye. Depending on the specific working protocol, it may be used, for example:
- to stain biological or technical specimens,
- in microscopy and demonstration procedures,
- in analytical and research applications,
- in laboratory or technical procedures requiring a methylene blue solution of a defined concentration.
The manufacturer also lists its use as an indicator in laboratory procedures. Its suitability, working concentration and method of application must always be determined by the relevant method or laboratory protocol.
Why choose a 2% concentration?
The 2% version contains approximately twice the concentration of methylene blue found in the 1% solution. It is suitable where a procedure specifically requires a more concentrated stock solution or where the user intends to prepare a working dilution.
A higher concentration does not automatically produce a better result. The correct choice depends on the specific application. Do not dilute the product by estimation; always follow a precise laboratory protocol.
- A 1% solution may be more practical for procedures requiring a lower starting concentration.
- A 2% solution provides more methylthioninium chloride in the same volume and enables a larger quantity of diluted working solution to be prepared.

Packaging and handling
The solution is supplied in a glass bottle with a dropper. The dropper enables controlled application of small quantities, but it should not automatically be regarded as an analytically calibrated measuring device.
For precise laboratory work, do not calculate the required quantity solely by counting drops. Drop volume may be affected by the angle of the dropper, liquid viscosity, temperature, dispensing speed and the design of the pipette. Where an exact volume is required, use a suitable graduated or automatic pipette.
How should the solution be handled?
- Inspect the packaging and the appearance of the solution before use.
- Follow the relevant laboratory or technical protocol.
- Use clean working equipment.
- Do not allow the dropper to come into contact with the sample or any other material, as this may contaminate the contents.
- Close the bottle securely immediately after use.
- Protect work surfaces and clothing, as methylene blue is an intense dye.
- Do not eat, drink or smoke while handling the product.
Safety information
For laboratory and technical use only. Not intended for consumption or internal use.
