Ok not an order but a special surprise.
18 months ago while in the process of moving house I picked up a pile of chems and equipment at a garage sale -- elderly gentleman was going into aged
care and his family was sorting out all his stuff including a home lab. I didn't have the time to look at what I was boxing up althought I did notice
that there was a lot of items related to testing water quality.
Today I was sorting things, wiping the dust off bottles and relabelling to put them into my new lab. Amongst the goodies was a small amount of silver
nitrate and about 500g of potassium iodate.
Also, I discovered that the drying oven that I thought topped out at 110C has a second setting (presumably a second element) and the thermostat goes
to 200C. I am yet to test it but I think the signs are promising.

That 500 grams of KIO3 is very nice. It also is of high value, this is an expensive chemical. Those always are nice surprises.

25 grams of 10% platinum on alumina
25 grams of 10% palladium on alumina
a liter of hexamethyldisilazane
A liter of chlorobenzene
A liter of toluene
2 liters of GAA
500ml THF
AND some zinc oxide! Whee! (never been that into zinc oxide before, but damned if PirateDocBrown's enthusiasm isn't contagious.)
No, joke. I really did get zinc oxide.

Picked up 1.5kg of copper sheet at a garage sale for five bucks.

I also got some lead and some calcium sulfate which weren't really at a bargain price but never mind. I am pretty happy.

It is far cheaper to make silver nitrate than buy it. I did this recently to silver flasks for Christmas ornaments. You can see a sliver of the silver
coin I used remaining in the left side of the beaker. Yield was 96.4%, essentially quantitative.

This just arrived today. I’m super excited because I’ve been looking for chloroacetic acid for a while ![:D](./images/smilies/biggrin.gif)

The company has kind of mixed reviews on Amazon, but I’ve ordered about $250 of stuff from them and had only good experiences.

You can do better focusing on temp control during drying process, and keeping a low pH.
Preservatives do a great job at what they do, but if you can do without them, do without them.

This time, I ordered a chemical for swimming pools, not a true lab chemical.
An "oxygen fresh and pure discount pack" for small swimming pools: 2 kg of pure oxone, K2SO4.KHSO4.2KHSO5, plus 1 liter of so-called "activator"
(don't know what it is and why oxone needs to be "activated", but it was part of the deal and could not be left out, maybe it is useful).
Oxone seems to be quite useful as a strong oxidizer (redox potential over 2.5 V), which also reacts quite fast (this in strong contrast with
peroxodisulfates, which react sluggishly). In theory it should even be possible to oxidize chlorates to perchlorates with this oxidizer in aqueous
solution. I severely doubt this, but it is an interesting direction of research. Getting cheap perchlorates is impossible with current regulations in
the EU (you cannot buy cheap NaClO4 and KClO4 anymore, only the much more expensive HClO4 and NH4ClO4 can be purchased by individuals without
license). Making chlorates is cheap and easy, but making perchlorates is hard. Maybe oxone can be used for oxidizing chlorate to perchlorate.

Ordered myself and received a litre of DCM, plus 500g of NaNO2 - will need to set up for a crystallisation for a thread I made a promise on
In chemistry, sometimes the solution is the problem.
It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.
