Hope I am not being rude to chime in with a shameless plug, but for stock parts like stoppers, custom making those might be a bit pricey. You can buy
them used or even new for not too much.
I have lots of loose stoppers in many TS# sizes and joint sizes, such as TS 8, ,9, 13, 16, 19, 22, 27, 32, and many more. They would be $1 for small,
$2 for larger ones (32 and above). Those are commonly used in sep funnels, volumetric flasks, grad cyl, and other glass containers. The US postage
for one stopper would be about $2-3, more than 1 would add only slightly more in shipping.
I also have 14/20, 19/22, 24/40, 29/42 and other stoppers for standard joints. They are $2 each, some are solid, some hollow, some designed as
reagent bottle tops.
And lastly, I have a box full of Teflon (and a few glass) stopcocks, in most normal sizes. The most common sizes are used in sep funnels, burets,
addition funnels, inlet adapters, manifolds, and more.
Also, if the glassblowing school can use any of the above, or if you have a use for a few new standard joints, valves, stopcocks, and other
glassblowing parts and pieces, I would be happy to donate some to you, I have a few items like that which I cannot use. Even happier to swap them
for some minor repairs :-)

Trading some components or parts for some repairs sounds like a great idea to me, Dr. Bob. I quoted the guy a few comments back for $25 plus shipping
for a small box to start, and $80 plus shipping for a big box. If you send us enough stuff to make it worth our time, we'd definitely be up for the
challenge. But as I mentioned in the comment above, do know that some things can break when attempting repair (not that I would ever charge anyone for
that.)

I'll send you an address, Dr. Bob. Just send us enough to make it worth it, and well send ya back some repaired goods.
Feel free to drop me a message if anyone else wants an address to trade some glass components or glass blowing parts to do some repairs.
I know I would sure like a Bunsen burner...
Keck clips and ring stands are nice too...

Would you guys prefer a dwg. file for a work order? ( drafting student here.) I am looking to have an electrochemical cell made( 2 liter or so but
the bugger part is the fritted barrier) as well as a few gas mixing flasks. in any case thanks! Its nice to see someone offering to us!

Very much so, Funkerman23. We CAD is a required class for the program. If you send us the file, we could very quickly establish whether it is within
our ability or not. The gas mixing flasks definitely sound feasible. my e-mail is ababino@studnets.salemcc.edu .

Looks like the vessel is typically priced at $188 USD, based on your link.
I think $70 plus shipping would be fair.
Though I can't seem to find exact specs for the piece online. It seems to be five threaded O-ring joints on top (four surrounding the central joint on
top, bottom, left and right, and one central joint with a hose connection slightly under the threads.), and two on the body toward the top (one at a
45 degree angle).
Would you happen to know any specs for this piece? (height/outer diameter/inner diameter/internal pressure needs) Are there any specs. I'm not
thinking of?
I hope this works out. This sounds like a very exciting project. |
I will get some specs
Seems a good price...............But what about discount for say 4-5 units?
I know someone who well might be interested

I have a Vireux column and a liebig condenser both missing their upper joints. I have no use for them (except maybe for reflux), if you want to try
repairs on them let me know the cost. (19/22)

The vacuum gauge thread piqued my interest.
I am looking into getting up a vacuum distillation set-up, and suitable vacuum gauges are an issue.
How about a mercury manometer?
Here is a picture of one:

It would just be the S-tube, with a 24/29 ST joint so that a vacuum valve could be attached.

Thanks for the kudos in the other thread, Dr. Bob. I'm glad the repairs worked out for you, and I hope ya send me some more stuff to work on. I'm done
with school now and have relocated back to the west coast for the time being. My schedule is much more open now should anyone else want repairs or
something made. I will also be making a few example products in the next couple of weeks and posting them for sale as examples of my work. I would
also like to say that I am very open to the idea of trading equipment for glass work.

This all depends on a few things, careysub.
Would you want mercury in it, or do chemists usually add it every use?
Are these all the same standard design? If so I could probably find one at the local college and measure it out, if not I would need a little more
info on your specific vacuum valve...

I could do a whole soxset of that variety for about $85, 2 neck rbf's for $30, 3 neck rbf for $40 of that same size. Let me know if you're still
interested sounds like a fun project!

Just wanted to throw it out there. I could really use some standard taper ground glass joints of varying sizes, or some manufactured hose connections
if anyone is wanting to trade for some glass work. Repair or custom.

I'm really interested in a solvent still glassware kit - 29/32 joints (prefer Duran / Pyrex / Lens glass)
The cost of Argon packed anhydrous solvents is killing me.
Let me know if you can help;

Can you fabricate one of these...
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).

That seems simple enough, Bert. Would you want all the extra components, or just the funnel? What size would you want the standard taper joints that
hold everything at the top? I don't know if I could construct something to hold it though. If you're serious about this I could seek out a local
machinist.

How much would the simplest glass diffusion pump (do a google search) cost to make?

Not sure if I still have it, but I had a broken glass oil diffusion pump somewhere years ago that I put aside to try to get fixed. If you wanted to
pay someone to repair it, I would sell it cheap and even ship it straight to the person fixing it to save on postage. They are not trivial to make
or use. Most people just use turbo molecular pumps now, like on most mass specs. But I remember using both oil and Hg diffusion pumps in college.
Also, if theglassguy is still on here and active I have a growing pile of broken stuff to try to repair again. I have a few addition funnels with
broken equil. arms and more glassware which I would love to get fixed again sometime. But I have been waiting until I get enough to bother with.
