It's a bit tough for even the kindest hearted of strangers to offer you appropriate (free!) equipment if you don't describe what kind of equipment you
think you need and the types of chemistry/experiments you are thinking you need that equipment for?
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

He had told me some info privately. I am working on a good deal for him, but have limited solid reagent bottles left. Still have a few narrow
mouth bottles left in a few sizes.
If anyone else is interested in scratch and dent glasseware, I do have lots of damaged filter flasks with broken vacuum inlets (or erlenmeyers with a
hold in the top), and some other odd pieces. I have some really old grad cylinders, some without graduations (either never had them or really work
off, could be fixed with a sharpie I think), and a few other odds and ends.

I have recently found a few older editions of the Merck Index, the bible of pharmacologists and medicinal chemists. Along with the previous books I
posted before, I still have a fair number of science books available, so if anyone if looking for actual science books (yes, bound paper), please let
me know, as I am trying to clean up more space of older books, and pass them on to younger scientists. All i would ask is postage at media rate, or
that you come get some if you come through NC, or I can try to get them to you.

Hey @Dr.Bob, seeing as this thread was started so long ago lol, do you have any undamaged beakers, (1 or 3 neck) round bottom flasks left, or perhaps
even distillation setups like the one you mentioned earlier in the thread still available?
Would love to buy some (am in northeast US) if you still do

I have a few beakers left, very few 24/40 rbfs, a good number of various 14/20 rbfs, plus one 14/20 kit left, and many pieces of 24/40 kit (I could
make a kit except I have few rbfs to go with it.). The best thing is to send me a u2u or email me at craigslistinnc@gmail.com and you can give me
more details on what sizes and such you are looking for. I have a shrinking list of things left, but I'm happy to do what I can.
I also have a mix of 19/22 kit, which is not really a whole kit as much as just a large mix of 19/22 stuff, might be ideal for someone who already
have some 19/22 kit already and wants more. I also still have some 29/42 kit left, but it is mostly 3 necked rbfs and most of what you would need
for a distillation setup.

Hello, I'm selling an empty co2 tank. It's good for up to 450ml of co2 and can be used for other gasses like nitrogen or argon.
Here are some images
I'm not very sure on what a good price would be so I'm going to start off at $75. DM to purchase.
Thanks

The rods would work, but I would also need something to use as a stand. I have tried using wood in the past but it does not work very well, mostly
because of how light the wood is and that it rots if you spill something on it.
Do you have any 24/40 addition funnels? If so I would like to know which sizes you have and I would be willing to buy one or two.
Thanks

If you go back oine page, there are a bunch of photos of what I had a few months ago, and I have almost all of them still, I think I sold a couple 250
and 500 ml ones. The pricing is in the spreadsheet also fouind on that page (28) and are:
110 Addition Funnel, equilibrated, 24/40, used very good - non-graduated 125 ml 1 $50.00
111 Addition Funnel, equilibrated, 24/40, used very good 250 ml 1 $60.00
112 Addition Funnel, equilibrated, 24/40, used very good 500 ml 2 $65.00
113 Addition Funnel, equilibrated, 24/40, used very good 1000 ml 1 $75.00
http://www.sciencemadness.org/talk/viewthread.php?tid=15667&...
If you scroll back through a few pages of this thread, you will see a good chunk of what I have left in 24/40 items, and many other bits and pieces.

This obviously isn’t my equipment and I don’t live anywhere near AU, but there is going to be a massive auction of lab equipment and supplies on
Sep 12 in Queensland. The prices would probably be pretty fair too, if anyone is interested.

That's a lot of stuff, maybe J-sum and some of the other other Aussie's can do a group buy of hotplates or other useful things. Clearly a huge
place or several business' worth of stuff there.

Thanks Dr.Bob!
Just wanted to give a shout-out to Dr.Bob, he helped me complete my micro-synthesis glassware set. Luckily we live in the same town, so that made
'shipping' much simpler!

Does anyone have some 14/20 ground glass stoppers? Currently i'm using an abomination wooden stopper I made on the lathe which is terrible. I try to
buy one but even one is so expensive

I have lots of them. I typically sell all jointed flask stoppers for for $5 each, but can make a deal if you want a few. I have 14/20, 19/22, 24/40,
29/42, and up to 45/50 and maybe larger. It would cost about $5 postage to mail a few with first class mail.
I also have the standard single number type stoppers like for sep funnels, grad cylinders, and volumetric flasks from #8 to #32 for $2-3 each, smaller
are cheaper. They are a different taper than flask joint type ones, not sure why, but they are. But they are cheaper, but they are not near are
well made, so not good for vaccum work, but not an issue on volumetrics and such.
I also have adapters from and to almost every standard taper joint size. These things and the prices are all hidden within the spreadsheet of
glassware I have posted.

Ok, what would an estimated price be for 4 14/20 stoppers, a thermometer adapter, two 100ml 14/20 3 necker (ideally with necks not at an angle but
vertical), a 14/20 gas inlet thing (ideally with the long injecting stem that goes into the flask), and a claisen adapter?
I live in MD if that can help to estimate shipping.

Just to make things interesting, I am in the market for some #29 stoppers, like what fit onto 1L glass reagent bottles. I have scads of bottles,
but am running out of the stoppers for the top. i would be happy to pay something for them, or trade them for other glassware, just need to be a
reasonable price. But if you have more stoppers than bottles or just have found some loose, I would be interested in making a deal, as the bottles
are not much use without a stopper. I do have lots of 24/40 bottle stoppers, far more than I have bottles, so I am happy to trade or sell them.
Just need to figure out how to grow them a little.
