What you take pride in...
What apparatus or chemicals do you highly value and treasure? I like my:
a. Sodium
b. Nitric Acid
c. Mercury compounds
d. Addition funnel
e. Radioactive Americium 241
f. My experience
g. My low life expectancy
I know... all are pretty simple and common, but I don't have a huge lab. I just conduct experiments for my enjoyment and to learn. Most of what I do
is small- between a few mL to a liter. I hardly ever work with more than a liter of my chemical. When I do, I do the experiment in a trash can. What
was I doing yesterday? Making CuCO3 in a trash can!
hey, if you are reading this, I can't U2U, but you are always welcome to send me an email!

a. ammonium perchlorate
b. hydroxylamine sulfate
c. 60% concentrated H2O2
d. jar of elemental bromine
e. 10mL of trinitromethane prepared and dissolved in chloroform
f. my energetic chemical sites
I'm not saying let's go kill all the stupid people...I'm just saying lets remove all the warning labels and let the problem sort itself out.

i covet nitrates. it took 2yrs. to understand what a nitrate was and how nitric acid was made. if it were not for bosco36 or bosco 96 showing his
method of making nitric acid on youtube,i would not have an idea.regardless of how it was described in literature it was out of my grasp and i wasnt
alone because no one around me had a clue either or else i would've learned it. many people dont have a remote interest in learning those things so
therefore have no idea as how to make those very same things.i was intent on learning how to silver plate and making my own salts. now i can somewhat
gold plate. thank you sciencemadness.org. sincerely cyanureeves . my username is taken from keeanu reeves because i could not correctly
pronounce the greek form of cyanus(cyanide)

i take great pride in my group of lions and my sense of humor and my ultra low freezers.
oh and some d2o i distilled from ordinary water water using a vigreaux column (thats what someone claimed they did once, very aggressively, they sold
it to natropaths (however it spelt), the key was he said to go very slowly))
also i take pride in my ability to keep tabs on my brackets.

Over the past few months, I acquired a very nice collection of glassware. Taking pride is a relative term, I am very happy that I have this very
useful collection, but I reserve my pride for my 25-year experience as a graphic designer, the nice house I've owned for the past 12 years, and my
success as a music festival organizer for 4 years.
On the chemistry side, the gear I like the most, and looks the coolest is probably my soxhlet kit with the elusive adapter:
Also my collection of condensers and vigreux, my antique but really nice hotplate, and my numerous distillation adapters. I have several chemicals,
but there's no pride in owning chemicals, unless you've synthetized them yourself!

Well, I did not do much synthesizing because I didn't find the time to acquire all of the chemicals I wanted.
But I do like my:
Na3MnO4 (got a really nice blue color, the color is even more potent then KMnO4 when in solution).
Germanium sulfate solution, practically useless, but a nice thing to keep in a vial.
My home built magnetic stirrer, works like a charm.
ah, and my a bit yellowish fuming nitric acid.

Psh, only 45/50? Mine is 55/50...and I have 3 of them. Couldn't pass up a really good deal when I saw it...
My Friedrich condenser is also awesome and while I do love my gear, my most prized chemistry possession is a tube containing ~1.5g of
6,6'-dibromoindigo, arguably the world's most expensive pigment of antiquity and in quantity equal to 12,000 of the murex snails from which it was
extracted historically. I prepared this by a multistep synthesis beginning with p-toluidene.

I love my home made iodine. So sparkly! Picture in another thread.
And i love my 2.5L bottle of ACS sulfuric acid. What got me started in this crazy hobby. My friend bought it on a whim for $15 and lots of people find
it so hard to get ahold of.

@ piracetam: Damn impressive collection, and that's your home lab? Wow! I'D love ti to get my hands on a rotovap and an autoclave. (wiping off the
slobber on the corner of my mouth) 
And I also use a Friedrichs condenser on top of my soxhlet, literature says that an Allihn condenser would be prefered, but mine is 19/38 and I don't
have an adapter for that. The Friedrichs condenser on the other hand is 24/40. It's a wonderful kit and I paid peanuts for it but I haven't had an
opportunity to use it yet.

thanks
yeah, it's a bedroom collection, hehe.
so lit. says that an Allihn is preferable over a friedrich? i find that hard to believe.
what would be the advantage? I mean, the friedrich should have more cooling surface area.

I agree, but there are many occasions where i've seen an Allihn condenser, even Wiki's page features one.
http://en.wikipedia.org/wiki/Soxhlet_extractor
But my glassware provider told me that when he acquired that lot, it was 8 sets of Soxhlet/Friedrichs/adapters that were used for vegetal extracts. It
does make more sense, and you don't need to plug in the condenser since air cooling is, or seems to be plenty enough.

*shrugs*
I actually prefer the friedrich condenser, it's effectively a coldfinger.
attach it to an RBF/FBF, and you have an atmospheric pressure macroscale sublimation app.
I inadvertently used it like this when refluxing tryptophan in mineral oil; white crystals formed on sides of the [friedrich] condenser; the
condenser was rinsed with acetone, and the sample was analyzed with LC/ESI-MS. the mass peak corresponded with Sigma tryptamine standard.

I like all my 3-neck RBFs (I have 6 I think). And my fume hood and PTFE lined lab-vacuum pump.
Chems:
-~10g. gold powder, a few grams of both Pd and Pt (as metals and compounds), 75g ammonium perrhenate and a few grams of RuO2 (gift from woelen  )
-10mL SOCl2
-300-350mL CCl4
-250g red and 15-20g white P
-900mL acetic anhydride

Heating molar amounts of NaOH and MnO2 in a beaker to about 200-250C over a course of an hour or how much it takes for all of the material to react.
The formula is 4MnO2 + 12NaOH + O2 --> 3 Na3MnO4 +6H2O.

in a beker??? 
NaOH eats through glass, and I think that it should be fused to form Na3MnO4...at about 350°C

Well, they should be mixed well, it doesn't eat through glass if it does not melt, just mix it well and stir it every few minutes. It barely did
something to the beaker when I prepared it.

If it doesn't melt ok!
Could you post the entire procedure please?
