That definitely looks more effective than the standard stirbar-and-a-piece-of-twine apparatus usually used in le labo de JJay.

Ha. Here is my attempt at the same thing:
https://www.sciencemadness.org/whisper/viewthread.php?tid=61...
I had a nice unboxing the other day:
300mm air condenser
a set of SS lab scoops
4 24/40 thermometer adapters. They are my favourite thing to break.
a Thiele tube ![:)](./images/smilies/smile.gif)
a packet of capillary tubes for the above -- only the diameter is too narrow. I will have to buy some more. Still, they will be good for
something. I should be able to draw up constant volumes of liquid for analytical work. Once I have worked out accurately what the volume is it might
be good for titrations. I am sure I will find other uses as well.
two 24/29 stopcocks with three way ptfe valve
I have a few more odds and ends of glass on its way as well as some items for my fume hood when I construct it. And I bought a vacuum desiccator that
should arrive within a week.
Unboxing is one of my favourite things to do.

Unboxing is a lot of fun. Every time a package arrives, it's like Christmas ![:)](./images/smilies/smile.gif)
I really need to get some SS lab scoops. I've wasted so many plastic spoons....

Have you considered spoons ?

or kitchen scoops ?

I recently got a 24/29 distillation, Claisen, vacuum receiving, and thermometer adapter.
Ironically, the only condenser I have with glass joints is my 24/29 graham condenser, but my Liebig condenser is reliant upon rubber stoppers. ![:(](./images/smilies/sad.gif)
Time to go hunting for more glassware soon again.

I am currently carrying a large military duffel bag full of glass from my latest order and will take photos when I get home.
A while back, I noticed a suspicious van that I suspected of being a surveillance vehicle watching my residence. Today, as I was heading out to pick
up my glass, the van drove up to me in the parking lot and the driver, who looked nothing like a cop (actually, he looked rather strung out) asked if
I knew "anyone who was looking for a laptop" and said, "Come on," when I declined. I am not sure what to think about this and wish I had asked him how
he managed to fuel his van.
Anyway, I'll post pics of my new glass when I get home.

If they are watching, they are wasting their time. I'm not doing anything illegal, and this is a fairly pedestrian collection of glassware.

Large scale chemistry much JJay? ![:o](./images/smilies/shocked.gif)
I bought a 250ml Soxhlet last month for about $30. I had some trouble at first but I've finally put it to good use doing some extractions!

I bought the 5000 mL beaker and 3000 mL flask for purifying metals. I don't consider this to be large-scale really, but I can't do it in my stainless
steel cauldron (which is actually just a 12L stock pot)... lately I have been doing most of my experiments in a 1000 mL beaker and 500 mL flask.
I still have not used my Soxhlet for anything... but extracting cocoa looks like fun.
Curcunoids, huh... from ginger or ?

After 5 hours of dragging myself through various antique shops, I finally found one that was selling some chemistry glassware!I got an amber glass
bottle for storing solids for $5 and a 2000ml. round bottom flask for $5 as well.
![IMG_8899.JPG - 2.2MB](http://www.sciencemadness.org/talk/files.php?pid=478423&aid=58198)
The round bottom did have some damage on the neck however but I suspect it should be OK.
![IMG_8901.JPG - 2.1MB](http://www.sciencemadness.org/talk/files.php?pid=478423&aid=58200)
Additionally, they also had this monster of a 4 liter vacuum flask for $30. However, considering that I rarely ever even use my 1 liter regular flask,
I didn't think I needed it (I don't think I should be doing vacuum with antique glassware anyways).
Current Active works in Progress:
-Convert i-propanol to i-chloropropane using HCl and ZnCl2
-Determine properties and solubility of a glycerol and citric acid polymer
-Attempt a conversion of chloroform to dichloromethane
-Attempt a conversion of acetic acid to acetamide

I have some pretty nice glassware, but there are still some things I want:
1. A quartz retort or distilling flask, preferably with ground-glass joints. This would be helpful for distilling sulfuric acid and oleum, as well as
distilling mercury, aluminum bromide, sodium and so forth, and it could be used for pyrolysis reactions that I ordinarily would run in a steel can.
This would give me free access to high-grade sulfuric acid at all times, not to mention hard-to-get reagents like thionyl chloride. I'm looking at
one, and I really want it, but it's going to cost almost $300.
2. A large crucible.
3. A Dewar condenser. Right now I would be limited to putting a test tube in a dry ice/acetone bath if I wanted to prepare some liquid ammonia or
liquid sulfur dioxide. It would also be useful to use one as a cold trap.
4. A chromatography column. I don't remember ever actually doing any column chromatography in chemistry classes, but I've done a lot of things that I
was never taught to do, and it looks like something I'd want to do at some point.
5. An argon tank and regulator.
All this stuff is going to be very expensive, and while I do have a job and few living expenses, it's going to take a while to save up for all that
stuff.

I would like a nitrogen tank and regulator..
also a Rotary evaporator ![:)](./images/smilies/smile.gif)
Also i really want to build or get a fumehood soon, thats my ultimate need-to-do item.
Also i need, or plan to, get alot more chemical storage glass bottles.
Also a coldfinger is something i will probably get for resublimation.

I picked up mainly an assortment of vials with a nice set of clear 20 mL PTFE septum vials and a whole bunch with paper-lined caps but also some
pipettes, a crucible, two media bottles, some flasks, alumina TLC plates, and melting point tubes. Oh and also my much-anticipated jerky dehydration

I have an order from Deschem that I made almost two months ago that hasn't arrived yet. I've bought a couple dozen items from Deschem, and that's very
unlike their usual level of service; while they seem to have mostly grade-B equipment (which is functional and a good deal for the price), Deschem is
trustworthy, and typically Deschem orders ship quickly and have no problems with customs or breakage. I emailed them and they told me that Chinese
customs is on a high security alert right now... I heard the same thing from my mail agent.
Some orders seem to be getting through quickly still, but there are definitely some customs issues right now, and I don't think it's just Chinese
customs.

It looks to me like some sellers are having an unfairly hard time with both American and Chinese customs. I'm not really sure why... Nanshin, who it
seems to me usually gets a lot of flack from Chinese customs (almost every package I ever ordered from Nanshin got hung up at some point and arrived
with that familiar yellow tape), is currently getting packages through quickly, though.

^ its almost easier to pay the higher price and get it from people already in the US. Yes ordering from china is way cheaper and ive done it alot. But
the more customs gets involved the more i start to think might as well pay the extra and avoid problems.

I think it really depends on what it is... if I'm buying a mercury thermometer I'll buy it from the U.S. I usually buy electronics and chemicals from
the U.S. If I'm in a big hurry to get a replacement item, I'll buy glassware from the U.S. But if it's just glass for outfitting my lab, I don't
really see a problem with getting it directly from China. Customs might delay my package in the name of making America great or whatever, but this is
a free country, and it's just a piece of glass. I figure I'm just helping some artisan buy rice for his family.
My guess is that the new administration simply changed tactics at the borders, so now customs treats packages differently.

Did I outbid anyone here? Got the package a week ago and the distillation head
is simply erotic. Looking forward to putting it to use. The jacketed Dimroth didn't survive the trip from Germany. No problem since I have a
glassblower in my immediate vicinity, paid her a visit yesterday to fix the breakage and to look for a suitable stopcock for the addition funnel.

What a fantastic kit ... I'm so jealous of the still head
(full reflux, variable takeoff, Perkin triangle ?)
What is the glassware bottom right ?

I am pretty sure that is a Soxhlet extractor. They're used with a reflux condenser for doing continuous solvent extractions (like this one: https://www.youtube.com/watch?v=wQidAZQhxbA).

That's what I first thought but I could not see the siphon tubes,
it has the same neck size as the double-surface large area reflux condenser on the left,
so probably something Soxhlet-like ... a simple extractor ?
.................................................................................
ooo! it is a Soxhlet, with Dewar-like heating ... I guess
NICE !

Yes! Everything! You cannot ask for any more in a single piece of glassware!
I've spent the last five years or so being jealous every time I see one, it's so good to finally be on the other side. Now, to get a 14/23 or 19/26
version to complement it...
My max bid was 160 €, and I'm still surprised that I got away with it. To be honest I was only interested in the still head, which I've never seen
sold for less than 300 € alone - I consider the other items just a nice bonus
I seriously considered buying one of those QF sluice-type variable reflux adapters from GB Laboratory Equipment for ~100 £ - and then I find this!
Very happy.
The "mystery" item is indeed an extractor, though it's (of course!) not a Soxhlet. It does have a siphon, though of a different, simpler design than
on my Soxhlets. I have no idea what this particular design is called or even used for, any insights would be appreciated! The main difference is, as
pointed out, that the vapor runs around the whole perimeter of the inner extractor body, thus heating the extract. It looks like using it without a
proper thimble can be messy though. I'll shop around for a glass one.
BTW, I'd highly recommend this seller - he communicates well and is very flexible, and even though the Dimroth arrived broken, he packs very well and
I can hardly blame him for that. He's got another auction with a few interesting items going on as we speak: http://www.ebay.co.uk/itm/232283895572?_trksid=p2055119.m143...
