Ebay supplier - legit or not?
Hmm... Doesn't this eBay store look fishy? 100g Se for 16 pounds? It's very hard to believe.

Oh, sorry. In that case, the prices are extremely low! Sorry for starting an unnecessary thread, but at least others know about the seller now.

I ordered from this seller before but I had to make a special inquiry for shipping to Canada because eBay only states that they ship to EU.

I have ordered many chemicals from this supplier and I am very happy with this. He has good prices and quite a few interesting chemicals. His selenium
is indeed very cheap, but it is of good quality (he has different grades, you should take the 99.9x % stuff). Sometimes he also has Te and TeO2 of
good purity, at other times he only has crude Te. Just check at regular intervals.
My best purchases from him were 200 grams of NH4ReO4 for just GBP 20 and 160 grams of RuO2 for GBP 40.

He is offering 100g of pure Te for 12 GBP right now. Would you recommend purchasing selenium (powder, not beads) or purchasing tellurium for
experiments? He also has 200g of sodium selenite for 12 GBP. I know these compounds are poisonous and cause you to smell very bad, and I have a gas
mask for protection against fumes/dust. The mask has a NATO filter and I cannot smell anything through the filter when I breathe through it. I can
also get 10g Te in crystalline lump form for USD 19 (including shipping). This might be safer because there is less risk of dust inhalation.

A bit off topic but this seller has started selling titanium MMO mesh again after not having any for quite some time. I purchased some before and it works great for chlorate cells  reasonable price too!
Speaking of the seller who is providing the Se and Te, i would probably get some of both just because of the excellent prices, bought the Te powder
today, can't wait!!  The powders are a little riskier as far as inhalation etc
but it's easier to use them very carefully as opposed to trying to bust the lumps up into manageable sizes for experiments which is a b*tch (in the
case of selenium anyways)

Alfa Aesar puts the perrhenate at 50000 NOK and the ruthenium oxide at 62000 NOK Together, that's 14800 €, 11900 £ or 18700 $!! You could buy a car for that! That's an UNBELIEVABLE find, Woelen! No doubt you have to be
extremely happy about it!  Have you tested the purities?

@barley81: If you can afford, I would buy both the Se and Te powders, but if you can only afford one of these, then I would go for Se. Se has a more
diverse chemistry than Te. I also purchased the Na2SeO3 from him. This material is of adequate purity, but not excellent. If you make a solution of
the Na2SeO3, then you should allow any insoluble matter to settle at the bottom, before conducting experiments with it.
The Se-powder I have from him is of excellent quality.
@Lambda-Eyde: I did not know that these compounds are that expensive! I also made an estimate and estimated at EUR 5000 or so. Both chemicals are
quite pure. The RuO2 dissolves in bleach when heated gently and gives a green solution (perruthenate, RuO4(-)), which on standing becomes red
(ruthenate, RuO4(2-)). On acidification and addition of zinc powder I get deep blue solutions of Ru(II). According to literature these indeed are the
typical reactions of ruthenium. So, these experiments confirm that indeed the material is mainly RuO2, but of course, it does not tell the real
purity. I think, however, given the results I had, that it certainly must be 90% or better.
The NH4ReO4 is a white solid, which dissolves completely, albeit with some difficulty. NH4ReO4 only is sparingly soluble, somewhat like KMnO4. I have
another sample of NH4ReO4 (5 grams for nearly EUR 50) and the NH4ReO4 from eBay shows the same reactions as the much more expensive material, so this
confirms it is mainly NH4ReO4, but again, whether it is 90%, 95% or even better cannot easily be determined.
Anyway, yes, I am VERY happy with these finds. As soon as these finds were on eBay, I purchased all of the material. The NH4ReO4 was sold in 100 gram
batches, 2 of them available and I purchased both of them and the RuO2 was sold in 80 gram batches, also 2 of them available. Lateron I have seen him
sell 25 gram batches of NH4ReO4, but these were much more expensive (a few tens of pounds for 25 grams, while I only paid 10 pounds for 100 grams).

I stumbled onto this site and thought I had gone to heaven. http://www.artcraftchemicals.com/products/
The metal salts section was especially interesting.

Artcraft is also totally legit. I have ordered several of these salts from them over the years and the stuff is high quality. They ship
internationally too.

Darn not silver nitrate unfortunately....

Chymical Pulverization.’ (John Friend, Chymical Lectures London, 1712)

I just got a quote from them today on 100 gms. of Hexachloroplatinic Acid, here's their reply:
$2900 delivered for 100 grams
Price good for 72 hrs
thxs,
-mj-
Does this sound like a good price? Considering the time and hassle of messing with aqua regia and acquiring the platinum. I don't know exactly how
much mass you gain for the chlorination but this doesn't sound like a bad price.

Assuming the chemical is anhydrous H2PtCl6, this contains appr. 47 grams of platinum, so you pay appr. $60 per gram of Pt. Of course you also pay for
the chemicals needed for making the hexachloroplatinic acid and the work of isolating and purifying it.
If it is the hexahydrate H2PtCl6.6H2O, then you have 37 grams of platinum in 100 grams of this chemical. So, you should ask the supplier whether it is
the anhydrous salt or the hexahydrate.
I do not know the current price of platinum, but with this info you should be able to decide for yourself if this is a good price or not.

It is the hexahydrate, sigh, I was hoping to cut some time, but with platinum down to around $1400/ounce, I guess I'm going scraping for platinum.

This is a great seller, and he sells nothing even remotely suspicious (by nature and(or) quantity). Yeah, if he sold some thallium metal or salts in
there, then there might be issues. Or if some of his elements were of certain isotopes, there might be issues. But as it is, this is a great seller
- no worries.

I bought 50g Se and 100g Te for a total of $42 shipped to the USA. I'm really pleased with the good prices. Otherwise I would have gotten only 10g Te
for $14.95 and no Se at all.

WARNING, The guy from lithuania selling chems makes mistakes.
I have recently been arrested for either/or manufacturing drugs or bomb componants, none of which is true.
I believe he has sent me two packages by mistake (addressed to me, but not for me). I know for a fact that one is deff miss labled and sent to me
(sodium bromide), also during questioning, I was questioned about chemicals I do not own and never have done, I believe this to be the second package
that is in the posession of the police.
I wont go into details as this may harm or influance any final desision by the police whilst they ponder what they do about the situation.
But I believe they are watching this guy, but as he fucks up orders and situations could/can arise from ordering from him, I HIGHLY RECOMEND YOU STAY
WELL CLEAR OF THIS PERSON.
Being turfed out of your house for 4 days and being treated like a criminal is not fun MM
thats your feedback, make your own desision

The police are just doing their job. If you pay taxes that is where your tax dollars go. Get over it.
If you're scared of getting a visit from the police you're probably doing something illegal. I've purchased both red phosphorus and iodine from
redbestoffers.com and never had any problems.
