Allihn condenser -- need some parts
Hey everyone!
About a year ago, I was in India, and decided to get some glassware. Glassware there is cheap, but still good grade. So I bought essentially 70% of
the glassware I have now from India and brought it back to USA (I don't have much glassware anyways).
In India, I asked for a condenser, and all they could come up with was an Allihn condenser. I took it (It only costed me 15 bucks!). But here's the
issue: I only bought the condenser. No parts, no adapters. A refluxing condenser like this would be very useful to me in the future when I want to
prepare some organic materials very easily. So where can I get parts? I presume this is a 200 mm condenser with 24/40 fit parts. I may upload a
picture.
The narrow part where I presume the thermometer or drying apparatus goes is chipped a bit, and the inside of the condenser is coated with a dark dusty
material. However, my main concern is the location at which I would get adapters to attach this to a 250-500 ml RBF flask.
Are there any sources that will sell this for cheap? I don't want to hav e to spend $50 on a few adapters.

Uh, If you're just refluxing, the male 24/40 joint goes straight into the female joint on the RBF. Or you can drop a claisen adapter between the two
and add a thermometer.

That's what I was thinking. It's like anything else, just put peg A into round hole A. If you have round hole B then search on eBay for a 24/40 to B
adapter (or just buy a 24/40 RBF).

question, to doubt any assertion, to seek for any evidence, to correct any errors. ... We know that the only way to avoid error is to detect it and
that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think,
free to think what they will, freedom can never be lost, and science can never regress." -J. Robert Oppenheimer

I took some pictures of the condenser a long time ago, sorry for the delay. I tried just putting the thing on a 250 ml RBF, it didn't work very well.
Is it supposed to be rather loose? I'm sure I need an adapter of some sort.
That will give a slight view of the male side (the side going into the condenser)
That's just the other side -- where the thermometer goes.

This looks like a condenser used with a soxhlet extraction app.

I come from the KISS school of engineering. You can work
wonders with plastic tubing ... if your temperatures are no
to high.
Buy it a bit smaller, put the end in boiling water and slip it
on. To remove it... slit it with a knife. I guarantee you cannot
simply pull it off.
