disposable ghetto condenser

<< < (2/3) > >>

Organikum:
The problem is that plastictubing doesnt transport heat well.
So if you go to make something like the described condensors it would be advantageous to use thin walled tubing or glass.
A metaltube with a thin coating of chemical resistant paint insides is easy and better than plastic or glass - cheap and disposable (test with HCl vapor for being sure).

Of course a condensor doesnt need flowing water, a sufficent large reservoir of water where the condensor is immersed in is ok, the main problem being weight.

SWIX tried something like that once, just reservoir of water, worked for little while but gradually water warmed up and reflux moved higher and higher. Even the bottle method the plastic tubing out the top gets too hot really but it still worked. Sometimes had to turn it off, let all heat dissapate, then restart because it can boil for something like an hour before the heat climbs up to the top again. That really drags the time out too. I agree metal tubing would operate better, but maybe a little more tedious to work with, dunno. But then you can actually cut the tape at the bottom and slide the whole coiled tubing system off in one piece as the tape on the outside holds it together, so you can keep it. So only have to make once from metal then keep it, good as. Just slide it on to new bottles. SWIX did with plastic coils sometimes, but usually threw away due to tape/plastic containing way too much forensic evidence.

SWIM is looking, but no luck as of yet on obtaining a real condenser.  So he has tried a couple ideas with some success.  Probably the best was he took 2 re-freezeable ice bags, (the kind that you put in your lunchbox or cooler)which seemed to do the trick, crude, but effective and no condensation.  SWIM just taped them together on either side of the cook hose.  If you experiment with this, remember that (SWIM almost stepped on his dick here)as they melt, they lose thier shape and may slide down the hose or fall off.  SWIM just happened to be looking in the right direction when his were about to fall. (even a blind pig finds an occasional turnip)  More worried about them knocking something over than falling.  As a fix, SWIM has taped them around a section of old hose when they were all thawed out, and is freezing them that way. Maybe today's road trip will find us a real unit and we wont need to see if it works.  Noticed that the hose discoloration all but stops at that spot..thats what we want, is it not?  How about air cooled?  SWIM was thinking about setting up the rig close to the AC unit and making a cardboard "hood" (beer box with a hole on each side, stick the hose through the holes and slide the open side over the face of the AC unit)for the hose and just turning the unit on.  I mean, the purpose of the condenser is just to get all the gas that leaves the vessel to reconstitute (rehydrate, reform...shit, can't think of the right word here)to a fluid and essentially "rain" back into the reaction flask, is that not correct?  Looking at the plans, it doesnt look like anything more than a water-filled jacket for cooling purposes, much like the old WWII .30 caliber machine guns.

Xaja:
'Condense' was the word you were looking for, as in condenser...  :-[

Hey that ice-bag still sounds pretty dodgy, I think you right about them knocking things over and also the high heat on the plastic below them not good.

Tellin ya the bottle is DIY perfect... but oh well good luck finding the real deal anyway always much better of course...

n00dle:
two fluroescent tubes, different diameters, one slid into the other one, adn the holes sealed with silicon glue (not very effective as tried) or cork, makes a rediculoulsy big 1m long condensor that can be shoved into any bottle via a cork stopper, to maintain reflux, or, as a condensor for distillation if you can orient the tube at a 45 degree angle, but have not found the easiest way to attach this to the cork stopper in the bottle yet.
