Sometimes in lab there will be an interesting result that would be good for fellow scientists to know but is not worth even considering publishing. In that spirit, I bring you random science fact. In the course of experiments, it became prudent to determine whether Rhodamine B will stain an apparatus made out of PEEK (polyetheretherketone) (http://en.wikipedia.org/wiki/PEEK), which is a rather good chemical resistant material. I prepared a 1M Rhodamine B solution in DI water (not all Rhodamine B dissolved by the way) and spun it in an apparatus completely made out of PEEK in conjunction with my undergrad colleagues. | (https://www.chemicalforums.com/proxy.php?request=http%3A%2F%2Fblog.chemicalforums.com%2Fblog-peek.png&hash=719738911f504a8001de34c0a55a5f0295bf739b) PEEK |
