What is the name for this condenser device?
Trying to find out if there's a specific name for this type of condenser here?
http://i.imgur.com/cC1tmS9.jpg
Reason being I'm losing my mind using tube type condensers due to their poor design.
http://www.mentorials.com/site/monographs/high-school/chemis...
With these modern setups, the condenser can only attach horizontally by means of a joint that bends down. Because the condenser is not the most
elevated point in the system, vapors tend to gather in the joint near the thermometer rather than inside the condenser. What should take maybe an hour
tops ends up taking multiple times that. It just seems that for basic distillation, old fashioned gear like alembics work so much better.
I've found the name of something vaguely similar, a Hickman head, but it's not the same thing.

I don't know. But in searching I found a femel condenser.

I think it's called an alembic. At least, very similar condensers used by medieval alchemists were called such. And, apparently, still are by modern
Hermetic kooks (http://crucible.org/pelican.htm).
Upd: yes, definitely alembic. Proper scientists call it that, too. https://www.pelletlab.com/alembic_distillation

Smells like ammonia....

this is an alemBEAK in a, in catalan, capitell, cap=head, english capital, the top of a column.
another type is the Al-quatara
http://www.destillatio.de/destille/destille/alquitara/index....
you can find this type of setup of glass in ebay.de
and you also can use an of this without the top joint for ter.

You are going to have to explain that last comment. Who the hell is miss crestind? And why are you saying goodbye?

Not a miss 
Did not realize that this setup was also considered an alembic. Thanks for the info all!

I base this in "projected intelligence" (free public info) + "intuitive intelligence" but of course you can, at your will, call this "pure shit"
I say bye because I doubt this person return here in a long time.
onother quiz: I post a message "a metal indissoluble in..."
and is deleted? I cannot find in the "chemistry in general" where is post, not in "the short question theaat" no in "detritus", which often go some
messages moved by the sysadmins.

That was moved to Beginnings, due to lack of references. The fact that your first instinct is that it was detritus'd seems to say something about
you... that's my intuitive intelligence of this situation...

Ah yes. I should read more carefully. I thought it might
be a pop culture reference that flew straight over my head. Apologies.
Alembek condensers. Pelican apperatus. Femel condenser. A lot of interesting things have been devised. I guess there is a reasion that these haven't
become standard equipment. Good to know about though -- might be perfect for niche situations or a springboard for novel ideas.

lack of references? the question is simple and clear, a metal indisoluble in common acids (read the list), so if it so difficult for you understand
the question myself or someone else will clarify.
detritus is the last option optable in the universe board of options,
read carefully and RELAXXX, from detritus like petrol many usefull things born.

I think it's a Femel. Alembics may have been the design-source for the Femel. I don't like the duct tape in the picture. Are those glassware repairs
or grease substitutes?

Looks like thay might have jury-rigged that joint.
The condensor looks like it might easily be made by melting around, and depressing the top of a standard boiling flask.....Weld on a tube, turn it
upside down, and shazzam....you have your condenser. Except of course, you would have a female, rather that a male joint at its bottom.
In earlier times, a good glassblower could have turned one out for you, in a jiffy....inexpensively too.
In those days, yer average glassblower was also kinda like a priest, he told no tales. And, what you were gonna do with this setup....Well, that was
your business!
I don't know what that aspect of the trade is like anymore.
Have things changed?

Not real sure why that person chose to use duct tape. I think they were trying to seal some gasses or something, but it's really overkill.

Not real sure, but all I know is that there's no glassblowers around my area. Glassblowing, amongst other hands on trades, seems to be a pretty rare
skill these days.

The Hickman still head used for microscale distillation looks very similar (though much smaller):

It looks like an inverted fraction collector for two small fractions. Usually the joint would be female. It might be something made specially for a
project.

Yeah, that's what I thought. It looked to me that it might be a device for collecting a distillate or something in the larger straight portion. Then
it could be heated and a fraction condensed in the diagonal side arm. But that would require it to be inverted. The male joint and upside down
writing in this orientation has me confused.
