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.

Super Cute, Fun, & Effective
Color: Lightgreen
This set of water flosser and electric toothbrush are just adorable! The shapes of them fit in the hands really comfortably, but also add to the cuteness as the shapes of the animals! Yes, this is meant for kids - so the toothbrush heads are small (for little kids), and the water flosser doesn't spray terribly hard. BUT they're still very effective. I especially like the water flosser. It can be taken into the bathtub/shower while bathing, so the spray doesn't end up going places we don't want water to go. It has a small tank of water, and I recommend using room temp water (rather than cold) so that it's comfortable on the gums and teeth. Also to note, the flosser doesn't work when it's sideways or upside-down - it needs to be held upright. This set is so cute, easy to use, easy to re-charge, and very comfortable. It's also very good quality - a great purchase. I love it!

Love that this is a complete set, down to the wall block for the charger! My daughter is 4 and absolutely loves this set. I personally feel like the toothbrush head is a tad small, but it does do the job well. Its a soft brush head, with plenty of replacement heads. The toothbrush and the flosser both arrived fully charged, and so far we havent had to recharge it, but we're only a few days in. So, it seems to have a pretty good battery life so far. (I will update my review if anything changes on that aspect) The toothbrush and flosser both stand upright independently on the counter, without tipping over. The water flosser is hard fir my daughter to do by herself. She sprays water everywhere, as theres several buttons on it and she cant seem to remember in time which button turns it off. I help her with flossing and its been going fine. Whether youre on high or low the water pressure is not too hard for a kids mouth. In fact, I think the low setting does nothing but rinse the mouth and basically teach the habit of flossing. We use the high setting and it does and OK job. I am a little old school though, and feel like nothing will top a good ole dental floss flossing, but water flossing is a safer route to avoid cutting gums or getting floss stuck between close teeth. The sound level is minimal, a fraction of the sound level my adult water flosser makes. It doesnt shake/vibrate too badly in the hand and theyre bith comfortable to hold, and size appropriate for my (4yrs) daughters hands. It comes in a really nice box, packaged perfectly, making this a great gift for your little ones. The colors and theme makes brushing teeth exciting and fun again for your littles :)
