only 25mg? i see you didn't shop around! I'd cancel that order if it's not too late. That's about all you get in those commercial test kits and they're about the same price! That amount is only good for about two baths or ~3-10 plates. Should be able to get at least 250mg for $100 - I got 5000mgs for just a few hundred and that was imported from a Japanese lab and freighted with dry ice. Take some time and shop around with google also email some local labs and ask them how much to get some for you (worked for me). Dont forget Fast Blue B is the other option to BB, its usually a bit cheaper too and only requires refrigeration not freezer, but its more of a carcinogen concern and results not as vibrant (please read this thread in full if you havent yet)
yes it seems true that BB gives a more "vibrant" result than B, I'm not sure if that makes it any more useful though, but hey its a thing of visual beauty to me and its so simple yet so powerful - the results reveal all! Grow out 10 plants and wonder why that 1 is a keeper? you'll soon know!!! lol, omg HOW GOOD IS SCIENCE KIDS!?!?I'm impressed with the definition you're getting with the Fast Blue BB, thanks again for sharing your discoveries!
I don't know about US but I don't think you need any credentials (or whatever) at all to get Fast Blue B or BB, it's essentially just a dye that you can use to test phenolic compounds such as those in strawberries (just google: "Fast Blue" phenolics -cannabinoids) so it's not cannabis-specific, and it's not on any "lists"So, I looked for Fast Blue BB here in the US, is this about where you'd need go if you don't have credentials?
They're so famous for not selling things. It would be a big surprise if they would send you anything. A VWR is probably about the biggest size of supplier that might sell chemicals to individuals and/or deliver to residences.
Google gave me a few sources for the BB last week - additional search terms might bring up more. It will not arrive cold and may have been made in India and never refrigerated. Google just might give you a source for the B salt on the first hit.
Oh and what I said about ether is after learning everything you need to know about dealing with peroxide formation and the ease of ignition. Once you've got that down it's no big deal. Except for the penetrating smell freaking out neighbors.

Anyway, TONIGHTS ROUND OF EXPERIMENTS STARTS NOW!!
EXPERIMENT NIGHT #3: DECARBOXYLATION
so when trying to figure out how long to decarb for, it seems 120C/248F for 1hr is ideal for both THC and CBD? can only go from what ive read, lol. Anyway my experiment tonight seems to back that up.
I took some bud from some random recreational strain (so expecting high THC low/no CBD) and made 9 x 70mg portions of it, and wrapped each one individually in a square of alfoil about the size of a cig lighter:

Then put all of them in my oven, one of these air forced convection style ones - yes the alfoil pieces were slowly blowing around the the whole time, only at the base though so no direct contact issue. I had it set to 125C (error range lets say 120-130), which was its lowest marked setting.

Then after 5 minutes i took the first out, then after 10 mins took the next out, then after 20 took the next out, etc etc every 10 mins until the last one came out after 80 minutes.

Couldn't even find Fast Blue B, let alone Fast Blue BB at eBay...
Sigmund-Aldrich, India, China, and the previous linked source were about all I was coming up with for Fast Blue BB with a Google Search, just as G.O. Joe suggested in the quote above. The linked source seems like a zero questions asked supplier, but it would be nice to know there are other US sources for price comparison, and with maybe a smaller quantity option, like the five grams you purchased.
you wont find it at ebay although i did see it once a month ago, and Sigma only sell to registered unis/govt/LEO etc so they're a no-go (pretty sure u cant even buy distilled water from them without being reg'd), but Fast Blue itself isn't a restricted product so all you have to do is ask one of your local labs to import it for you, that worked for me. There are plenty of labs that sell both B and BB, mainly in China though i got mine from Japan. And remember just because you can't find an "Add To Cart" option doesn't mean its not available via an email either keep shopping around, take the time and dont give up, you'll find some and at good price - "the chase" is worth it! I dont know how much B is used (seems similar) but 20mgs of BB seems about right for 1 bath, which is enough for at least three full plates, so should get approx 50 baths out of 1000mgs. Do try and get BB if you can if only because its considered safer than B in regards to carcinogen, and you have to deal with it as a powder every time at least initially before you solute the bath.
So it turns out just shaking it harder in a jar doesn't make some of the clumpy bits dissolve ... I wonder if it's because im trying to dissolve them in NaOH 0.1N solution - perhaps dissolving in water first is best?
Joe i'd love to hear your thoughts about this
btw i wonder what dye might be used to show terpenes?
i was doing flower samples, whereas they were doing 1) tiny dots of probably just 1-5 microliters, of 2) hexane extract
