ChemWorld Methylene Blue is an ultra-pure, pharmaceutical-grade Ph.Eur. Despite the supplier's testing, we verify these tests in a Polish laboratory. We always do this to ensure we deliver a contaminant-free product to our customers. Tests have shown no heavy metals or other impurities.

Compliance with the requirements (Ph. Eur.) proves that our methylene blue is manufactured and tested to the highest standards, free from harmful contaminants and heavy metals such as lead, arsenic, cadmium and mercury.

Product advantages:

✅ Professional pipette - dropper

✅ Pharmaceutical purity grade Ph.Eur.

✅ Product tested in a Polish professional laboratory

✅ Correct solution recipe

✅ Laboratory-confirmed Methylene Blue content

✅ Laboratory-confirmed absence of heavy metals

We also verified in a Polish laboratory that our formula was correct and that customers were receiving exactly 1% methylene blue in an aqueous solution. The test showed that our methylene blue solution was no less than 1%, and even slightly above. This guarantees the declared potency.

Properties:

  • Solubility:  freely soluble in water and alcohols, forms an intense blue solution.         
  • PH dependence:  its color changes depending on the environment - in acidic solutions it takes on a cationic form (more intensely blue), and in alkaline solutions it can be reduced to a colorless leuco derivative.     

Reduction and oxidation:          

  • It can be reduced to methylene leucoblue, which is colorless, but reoxidizes to methylene blue upon contact with oxygen.
  • It acts as an electron acceptor and donor, which is why it is used as a redox indicator.      

Reactivity: 

  • In a reducing environment it can be transformed into methylene leucoblue, which is used in chemical reactions and biological research.
  • It can react with a variety of biological substances, such as proteins and nucleic acids, making it useful in microscopy and molecular biology.
  • It is relatively stable, but may degrade in the presence of strong oxidizing or reducing agents.     

Applications: 

  • Redox indicator – used e.g. in chemical analyses and biological tests. 
  • Biological dye – used in microscopy to stain preparations. 
  • Application in aquariums – used to color water. 
  • Fluorescence, exhibits fluorescent properties under certain conditions.

PRECAUTIONS:  If swallowed, do not induce vomiting; rinse mouth with water. Seek medical attention immediately. In case of contact with eyes, rinse with plenty of water and consult an ophthalmologist immediately. In case of skin contact, remove contaminated clothing and wash skin thoroughly with water. Immediately immerse contaminated clothing in water and rinse thoroughly.

STORAGE:  Store in a dry, dark and cool place, out of reach of small children.

As with all stuffed toys, supervision is needed.
I have a 6 month old standard size Golden Doodle who has gone through several raccoon toys. He loves their tails and to make them squeak. He knows the word raccoon, so when the last one “died”, I had to get another. This one is well made and has a magnificent tail. It did not take long, however, for Marvin to amputate two of the raccoon’s feet and pull the stuffing out. Luckily, I was able to get it from him before he swallowed any, and was able to sew up the injuries and return it to him for another round of play. I do not expect more from a stuffed toy, but I do not leave my dog alone with one and accept that supervision is always necessary. This raccoon is charming and when it “dies” I will probably buy it again. Five stars!

My Cardigan Corgi loves this toy!
My 33-lb. Cardigan Corgi loved her raccoon toy so much that she finally tore off its tail and I had to get her another one. Good toy for a medium-sized doggo.

Bought this because the picture looked like one my dog already has (he carries it around everywhere but it has a hole so I wanted a new one). It looks very different in person and is a lot bigger than I expected although it's still a cute toy. Just didn't look like I thought it would!
