ChemWorld Methylene Blue is an ultra-pure, pharmaceutical-grade form of Ph.Eur. Despite the supplier's testing, we verify these tests in a Polish laboratory. We always do this to ensure we deliver a product to our customers without impurities. Tests have shown no heavy metals or other contaminants.

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.

interesting analysis of what 'being creative' really means
This easy-to-read absorbing book is based on lengthy interviews with 91 creative individuals ranging from Nobel prize winners to artists to CEOs. Csikszentmihalyi starts by debunking the myth of 'the lone genius having a brilliant idea as if by magic' and defines three necessary ingredients for creativity ('with a capital "C"') - domain, field, and individual. Creativity must take place within a recognised domain (such as physics, painting and so forth); be recognised by experts in that domain (the field, although this may not happen in the individual's lifetime, eg, Van Gogh); and of course come from an individual, although he also adds the painstaking work that precedes and insight, the reality that all creativity builds on what has gone before, and the social elements of the creative process. The book also offers supporting evidence from the lives of the 91 interviewed, which also provides interesting insights into their lives. In many ways, this book is a biography of the creative individual. Also contains a chapter with quite practical guidance on how to live more creatively. Prescient advice for a book published in 1996 given the increasing profile creativity is getting in business and public life. HIghly recommended, one of the most interesting learning experiences i have had in a long while!

Very enlightening for those who truly appreciate creativity more than cleverness!
Format: Paperback
I love how the author almost redefines creativity .and sheds new light (for me, at least!)on what what real-for-true creativity is and how it benefits individuals and society. It's far more than simply brightening up a room with new wallpaper and curtains -- it describes how genuine creativity requires a thorough working knowledge of the fundamentals of any given field before one can truly create something new or better, and it reveals how those of us who aren't capable of creating something ourselves can yet be part of the process by demonstrating appreciation and support for those who create, whether as sponsors, patrons, or even just ardent fans!

instructive but limited
The testimonies of creative people that give this book its flesh and blood provide fascinating examples of creative people at work. That said, if a journalist had written the book, it would be more readable, and I don't think any less of an intellectual contribution. Moreover, the definition of creativity is elitist and stunts the topic (as observed by other reviewers): "Creativity is any act, idea, or product that changes an existing domain, or that transforms an existing domain into a new one. And the definition of a creative person is: someone whose thoughts or actions change a domain, or establish a new domain. It is important to remember, however, that a domain cannot be changed without the explicit or implicit consent of a field responsible for it." Given the people interviewed, much more needs to be said about the function of social institutions in promoting creativity. Many of the accomplishments lauded in this book would never have happened without grant-making agencies (e.g., NSF, NIH, HHMI) or non-profit employers like research universities and hospitals. To offer just one obvious example of the difference made by one's institutional context, the author had advanced students to help him do his research for this book. The elitism of the definition is even clearer in the role that marketplace plays as a judge of creativity. None of us buys books from amazon.com because some official group validated amazon.com as a good idea. We didn't wait for computer programers to affirm and certify it. Amazon.com is not deemed successful because it impressed its peers. It is successful because millions of us purchase goods through it. Similarly, auto-executives did not make the minivan a successful idea, millions of shoppers did. (Obviously I don't think the marketplace fits into the author's definition of creativity. If 300 million American consumers comprise a domain with 300 million judges, then the word no longer has any useful meaning.) The definition also precludes that countless ephemeral acts of creativity that take place daily. I think instantly of two women I have worked with who were great at holidays. Their clever costumes or decorations brightened my day, adding a little element of surprise and delight. Their acts of creativity don't meet the definitions of this book. The way that creativity is defined in this book is simply a filtering mechanism by which the author selected the people he would interview. It is not a definition of creativity. It is only a description of a subsection of creativity, the kind where institutions provide paychecks to highly practiced individuals to work hard at what they love. I also found little new to take away and apply to my own social existence inside the organization where I work. Perhaps I can summarize my dissatisfaction by observing that the subtitle sets out an agenda for the psychology of creativity, but the definitional filter is intrinsically social. This disconnection sets the book up to fail. So, count this as a negative review, yes, but I did enjoy reading the testimonies of the people interviewed, and the author adds some value in the generalizations he draws. Still, much, much more could have been said.

Wise and Complete
Format: Paperback
I've read a lot of books, too many, on creativity, and this is by far the best, the most complete, the most interesting. The idea that creativity comes out of immersion in a domain or field seems absolutely right and the idea missed by so many other writers. I'm a writer and a painter and I've learned that I'm not going to be any better than the work I've come to know and love, that I have to live in that work. If you want to be a better string player, play with a better ensemble. In many ways a creative person is someone who is in a conversation with what has come before, with work that excites her, teaches her, challenges her. This book makes that plain. But he has other insights as well, especially about the creative personality, the interesting dichotomies. Just read the book.

Creativity which has the power to change the world
A few caveats to those who are generally interested in creativity studies: Csikszentmihalyi's analysis and discussion of creativity does not directly relate to those who are personally creative. People who enjoy engaging in creative activities are not demoted, in his terms, but are simply not a part of the study. It is unfortunate that his language makes it seem this way; he distinguishes between the two by saying that Creativity has the power to shape a domain or the world, while creativity applies to those who enjoy coming up with new recipes, who are engaged in research that may not change a domain, but may "tweak" it, etc. What he is trying to discover are the underlying principles and traits of creativity in those whose work has made a significant change. Think Albert Einstein, Eleanor Roosevelt, Mark Strand: people who are either widely known for their influence, or who have been influential within their area or domain. This book provides an interesting view into the minds and work habits of Creative individuals, and concludes by offering general advice to those who wish to make their own lives and work more creative. It is a useful book, but one which requires a great deal of supplemental reading, in order to truly engage in creativity studies.
