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.

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review! My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.

So cute
Size: Large, Color: Pumpkin
My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. They are a bit heavy and awkward for my dogs to hold onto but they do like them.

Cute toy and super tough!
Size: Small, Color: Lobster
My small dog is a serious chewer, and this lobster toy has been holding up great. Usually, he destroys toys within a day, but this one’s still going strong after a couple of weeks. The shape is perfect — easy for him to grab and chew, and the little claws keep him entertained. The filet mignon flavor must be good because he goes right for it every time. It’s sturdy without being too hard on his teeth, and it doesn’t leave any mess or pieces behind. If you’ve got a small but mighty chewer, this one’s definitely worth it. Cute design, lasts forever, and keeps my pup busy — total win. 🦞🐾
