MB Sure Methylene Blue powder works out to be cheaper than liquids due to a variety of reasons including shipping, packaging and handling. So if you are ready to prepare the concentration yourself, powder will work out to be better. Also, powder can be stored for 3 years and since we ship in multiples of 1 gram, it does make handling very easy as you only need to mix what you plan to use.

However, if you need the convenience of a readymade solution, then liquids are better.

Mix 1 gm of Methylene Blue with 100 ml of water to make 1% solution

Mix 1 gm of Methylene Blue with 1 liter of water to make 0.1% solution

It is an experiment to showcase how oxidation, reduction and a catalyst work. It forms colorless Methylene Blue solution.
Steps:

• Take 1 ml of 1% Methylene Blue.
• Add it to a glass of water along with a spoon of sugar and a pinch of potassium (potassium is optional).
• Stir well - you will get colorless Methylene Blue.

Reason : Methylene Blue reacts with oxygen in the air and undergoes oxidation forming colorless methylene blue. It will revert to its original state as more oxygen is mixed.

You can achieve the same result if you mix ascorbic acid instead.

Methylene Blue is a stable compound with a long shelf life. It should however, be stored in a dark, dry and a cool place. Ideal setting would be store it in a dark place around 15-20 degrees Celsius. In powder form, it can easily be stored up to 3 years.
