HiMedia GRM980-100G Rhodamine B, Practical Grade, 100 g

As a layman, and using for hobbyist/nerdery purposes, this is, without a doubt, the most concentrated, potent dye I have ever been privy to.Imagine taking a single hair from your head, touching the powder with it delicately, and then putting it on a porcelain plate. Now, run the plate under running water. You will see, as if by magic, a stream of fluorescent red dye stream from that spot for a small length of time, before it runs clear again. Were your fingers anywhere near the water? Well, now they are stained red, haha. Whoops!Well, time to give the plate a quick, additional rinse before you put it back and-- what's this? Somehow you see even MORE redness stream from the same spot, inexplicably. How is this witchcraft happening? Oh, and now you've stained your shirt while looking at the water magically dye red, still. Well, that isn't coming out in the wash, but it's worth a shot.Well, time to take your clothes out of the washer and UH OH, they are ALL PINK. At least they look rad as hell under a blacklight. Just like your plates. And your fingers. And everything else you own, because it is all red from that bottle of magic powder that I'm pretty sure Jesus used when doing the water into wine trick for the masses.Joking aside, this stuff is legit, and you could dye the entirety of the great lakes with one bottle of this stuff. Good fun if you like playing with fluorescing liquids! Just... be careful when you initially muck around with it if you don't know what you're doing, or you could have an entirely pink wardrobe like I̶ d̶o̶ my friend does.Would buy again - and planning on making more purchases from this seller very soon!

The media could not be loaded. Great fluorescent performance. Brilliant fluorescence.

The rhodamine arived fairly quick and the price of the product was very cheap for the amount that it gave me highly recommend.

Great - just what I hoped for!
