You're the one doing the periodic table display, right? Did you ever get any ruthenium? I could send some. Also I have some nice selenium samples, if you want. But I'd actually be quite interested in that sodium bromide.


Yes. I have selenium powder now but I still do not have ruthenium. As for the sodium bromide, I would be interested in trading for ammonium chloride, choline chloride, or an MMO electrode, whatever you think is a fair deal. U2U me.

Filtered some precipitated ruthenium. Can probably recover several times this amount. Interested?

BTW, anyone I'm late responding to U2U messages, it's because I'm super busy due to moving today. I will get caught up over the next few days, once the hard part is done.

Still behind on sorting everything out here. Haven't been able to go through my chemistry stuff, due to it not being stored nearby, and the fact that I don't have a car. Have to rely on others to access it for now. Everything is uncertain, and it's really annoying.

I do have P2O5 in my stuff. A decent amount of it too. It was a little disappointing using it though. It's super powerful as a desiccant, but almost never gives clean reactions. It also turns into a thick gel almost immediately, which then becomes a passivating layer of sorts for the rest of it. This can be mitigated by coating silica gel with it, but it still tends to turn many organic compounds to tar. It'd be most useful as an inorganic reactant, I'd imagine.

Recently, HEET changed the design of their bottles, and the new, larger caps fit neatly onto the standard 100 mL glass bottles. The old caps fit onto 25 mL and 50 mL bottles, generally. The old bottles tend to be seen more in places that don't turn over their inventory that quickly. Whereas if you go to Walmart, you'll probably only see the newer ones.

This might be a bit out of the scope of this post, but a seller on ebay has listed 25 kg of hydroxylamine sulfate for $330. This is a great price per kilo, but of course that's a huge amount to commit to buying. Would anyone here be interested in doing a group buy? I was thinking we could get 5 of us to commit for 80 dollars each (the extra covers shipping) and I would then send out 5 kilos of the hydroxylamine to everyone.

All of my net worth is tied up between a cryptocurrency claim and a Labor Department claim. Should have a lot of money coming my way eventually. I wish I knew when though.

Close! I'd need to scope out places that'd be okay with me setting up a fume hood there first.

I am still looking for a lab quantity of red phosphorus. Ideally I'd like to get 500 grams. I am extremely reluctant to order it from outside the U.S. due to potentially draconian enforcement of shipping regulations. I am not in a big hurry, but it would be a nice thing to have.

I would really like some

NaBH4 and/or LiAlH4

I am not comfortable ordering from local Australian supplier, and 90% won't supply to end users anway and I'm not comfortable ordering it from ebay as all I buy from ebay is chemistry related items. (nothing like condensors anyway... the police WILL come to my house)

I was more than happy to sign the EUD for all my lab glass and the 2 year period has passes so theoretically the supply company discarded my records or at least is no longer obliged to show the to the police if they requset it. I just don't trust them. Not the lab supply place but the government.

NaBH4 and/or LiAlH4 are not illegal here but they are classed as category 1 precursors (as is pretty much anything useful) we have very little explicitly stated rights in my country, all our rights are by implication under Commonwealth law which means any lawyer can fight for or against them.

The aforementioed chemicals are not simple things to make and are useful for so many things. I'd be happy to buy a small amount from anybody that has them. I don't have anything of interest to swap at this point as I am just starting out. But I would love to add these to my collection to be used at a later time when I have more knowledge and experience not to mention more chemicals.

I've got a good bit of NaBH4 to offer for sale or trade. I'm in the U.S, so that limits me to only domestic offers.

U2U me if anyone is interested!

If anyone wants to be a part of a group buy on hydroxylamine sulfate, U2U me. Right now I'm thinking that everyone'll pitch in 80 bucks and I'll send out 5 kilograms of hydroxylamine in return. We need at least four other people to make this work though.

I have some burette's, most are fairly old but unused. Majority are goldline class A, I have a 1960's calibration certificate for them!! They havnt been used since this was issued lol.

Not sure of volumes and markings etc, i will post some pictures later if anyone in the UK is interested.
Also i am about to order several chemicals in bulk, if anyone wants some let me know.

these are in 25KG or KG amounts, I need to know amount your interested in as they will need to be repacked.
Potassium Hydroxide
Sodium Hydroxide
Potassium Nitrate

Min order quantity is 500g, not sure of price yet but will be below lowest on ebay UK. I might add some more to list shortly

So I've now got two people interested in hydroxylamine. We only need two more!

On another note, I recently managed to score some nice rhodium beads at an incredible price. Does anyone here want to purchase a small (~1-2 gram) bead for an element sample? I can offer a reasonable discount on the spot price. I'll post some pictures if there's any interest.

I wouldn't mind a rhodium bead, if it's under the current spot price - $60 a gram is not within my price range...

I'm looking for some glassware of 24/40 and 14/20. I need a 24/40 straight path condenser, distillation head, thermometer adaptor, and boiling flasks of different sizes. Also I'm looking to get my hands on a 14/20 distillation set up.
Also looking for cyclohexylamine, GAA, and some others

For trade I have:

Acetic anhydride
Red phosphorous
Benzaldehyde
Sodium perborate
Sodium bisulfate
And some others let me know if you have anything in particular maybe I will have it.
