Devongrrl: they sell stuff on ebay, generally at extortionate prices. If I remember correctly one product of theirs is benzyl alcohol, 50ml, and they want about £10 for it!! Outrageous!

Their prices are a little on the high side, but their customer service and delivery are excellent. I've ordered tryptone, bovine serum albumin, Tris, and other bio lab reagents from them, and have been happy every time. For a recent demo we needed lysozyme overnighted on short notice, and they got it delivered with no difficulty.

Speaking of Bio-World, Spectrum, etc - I have always had a simple test. Silver Nitrate. If they are asking for close to $10 a gram, the place is too expensive & often looking for university contracts rather than sales to individuals or small firms.

Since these places are almost always selling 500gr bottles of AgNO3 for $465-$529, a gallon of HNO3 and a few ounces of silver could make a serious profit on eBay.

Here is my secret, I found potassium nitrate and ammonium carbonate at a Chinese grocery store. You need to recrystallize the nitrate though.

Ethnic businesses often have a cultural bias and prefer products
in a pure or crude state. A local Chinese hardware store here
stocks liter plastic bottles of strong Sulfuric acid ( drain cleaner )
and granular Sodium Hydroxide in plastic jars like red devil.

The Chinese grocery store in my area also stocks pure granular NaOH in 500g plastic jars (as drain cleaner). Haven't looked to see whether they have ammonium carbonate or saltpeter.

Pretty expensive (being close to a one US Dollar per gram).... but I do happen to know that production-runs of picric acid are not continuous. That is, the chemical company will mfg a certain unit weight and stop (perhaps 10Kg) - selling off what they have.
I would bet that the production run is well noted on the containers. Even though it's water saturated, the company most likely get's visits & stipulations.

Well, they do seem to have something of a monopoly in the "High Explosives Online" business. . .
I actually briefly considered placing an order before coming to my senses.
And, unless I'm misreading the page, they seem supply it in the dry state as well as in aqueous and alcoholic solution. . .
Gram staining, anyone?

But if you're in the US (like me) - you'll pay out even more in shipping!

One time I really made an effort to compare the highest quality picric acid I could synthesize to commercial picric acid. I had a friend at the university in town and he really had access to the lab, free and clear. We had a damn good MP machine, electron microscopes, comparative microscopes, most anything a fine university lab would have. I can say with confidence that if you really work at it, you can produce a product that is reagent-grade & as high quality as a Fisher, Spectrum, or Merck product.
The only advantage I could see - is actually HAVING a production quality sample to compare with. But I feel VERY confident that many hobbyist chemists with a degree of care could come damn close to a great deal of reagent grade materials.

The one thing I wish is that I could find samples of commercial styphnic acid; as I have a collection of notes from several years back & the styphnic acid I made, I was quite proud of. I would have loved to compare that to a real commercial sample.
I really don't think it's smart to keep a lot of materials about but a collection of slides and a sealed gram-level sample of the best lab one has put together IS worth keeping - if only to see if you nailed it right on the money.

Delivery within the UK itself is pricey, but with PA, it's the possibility of unwelcome attention that's offputting; I did though (and will again), buy 35% H2O2 from them through their eBay outlet.

Soap making shops sell pure NaOH and KOH by the kilo. KOH is used to make the liquid hand soap.

I could be wrong of course but the guys in the UK have a tougher time with OTC chemicals. .....Most likely due to a hold-over from the troubles in N. Ireland & the cowardly 7th July attack.

A thought on iodine: it appears that ethylene diamine diiodide (aka EDDI) is sold as an animal feed supplement, and at rather good prices (in terms of cost per unit of iodine). For example, one online source lists 400g of the supplement for sale for $7.32. I'm pretty sure that acidification and oxidation (H2SO4, or HCl+H2O2) would yield free iodine. You can also buy KI from United Nuclear, but that's $8 for two ounces; not as good a deal. Tinctures and such have very little iodine and are not economical sources.
On the other hand the supplement may not be 100% EDDI (may have filler). Still seems like a reasonable source though.

I am interested in finding a source for bulk anhydrous AlCl3i dont really feel like making my own.... sigma has some 95% pure 2.5 kg ~$148.00 not bad at all.. but its sigma...

i have accounts with Bio-world and a few other chem suppliers and all went well, Why is sigmaaldrich such a no no?

If someone with an account could buy something like the AlCl3 and resell it to our community that would be desirable. Is this very frowned upon here?

For CO2, two very easy sources are:

- 10oz canisters for sodastream machines
- compressed for paintball guns, 9oz and 12oz sizes as a rule

I don't understand how can someone buy picric acid online, perhaps you need some "explosives license" to buy? I somehow doubt they would sell it to anyone.

I've seen picric acid advertised online as a bio-stain . . .
An explosives license seems superfluous if you're working on bacteria!

Stasis i have b.b. gun cartridges and have been wanting to make the carbonate from my kOH. any ideas on what kind of slow release gadget i could use to bubble C02 into the KOH solution?

They have valves for these little CO2 cartridges (threaded ones) for inflating bicycle tires. You screw the valve on to puncture the cartridge and then unscrew it (a little - not all the way) to release the gas. If you just unscrew it the teeny tiniest bit the gas MAY come out slowly enough for your application? Dunno, guess you'd have to try it.
