Improvised still pics up!


I have managed to make a kind of still sorta thing. Made from flurecent tubes. It even has a viguerx column!

Still info and pics

I hope some of you hard core chemists find this interesting.

nice work! with some practise it is obvious that one can learn how to make
glass aparatus themselves.

but remember that fluoroscent tubes are made of soda glass, so it can take changes in temperature nearly as good as pyrex e t c. These glasses are also much more difficult to work with since they have a much higher softening point.

just be careful and dont expect it to survive a 200+ C distillation unless being very careful. The thin walls helps to reduce temperature difference between outside and inside of the glass.

I once tried to concentrate battery acid in a normal incandescent lightbuld, used as a round bottom flask. got it to about 300 C and heavy fuming.

Worked fine until I removed the heat and cold air got to it. Crack ! no fun, no good but I was prepared for it since I was curious about how it would work.

Big halogen lamps are made of quarts or heat resistant glass, the one over 1000W become red hot in the glass after a few seconds!!

looks good!


I rotated the pics for you (you have to use an image view/manipulation program to do this, like IrfanView). You get them here:
(right click, "save as";)
- first picture
- second picture

Tell us how it works! And try it with something whats not expensive or hard to get and more important not dangerous first.
My stuff never works on first try :( ....

Thanks Organikum. Would any of you be interested in me making one with a proper condenser, vigurex column and a 135* angle still head plus a recovery bend? (sorry no vacuum adaptors :P)

I can start working on this on friday (get paid). I need to get some more tubes and some nichrome wire.

Note of Caution


Only dismantle fluorescent tubes in well ventilated areas, as they contain mercury vapour.

I was wondering: Is the mercury vapor in a partial vacuum or is it near atmospheric pressure? Isolating it would be quite useful, taking the necessary precautions, of course.

There is no mercury vapour in light tubes but a very small amount of metallic mercury (about 25miligram as I remember)

The white stuff lining the inside of the tube which turns the UV to visible light is more dangerous to health, so wearing gloves whilst brushing this stuff (and the mercury) out and down the drain is advised. And no, it is no big sin against environment - the sewage handles this with easy. The amounts are tiny the precautions are mainly directed to avoid as much unnecessary stress for the immune system as possible - the overall level is already high enough.

No offense intended fish, only trying to debunk myths. In a world full of false warnings who will be able to recognize the real dangers and who will listen to the serious warnings after this?

enough of seriosity - glassware is topic! What about this nice midscale RBF?
(no, not mine LOL....)



And this is actually mine (also I will again get accused to show off with glassware)

Damned.
This looks like I am trying to steal the show from blindreaper. Sorry - wasn´t intended.

I admit freely to be quite disabled in working with glass - some lighttubes straight - everything else broke.



And thats it. I bow my head before blindreaper - you have talent for sure!

It is not a vacuum. The were gone long ago! They are now filled with an inert gas such as argon but for longer lasting bulbs they have krypton. I was scared to shit the first time I tried to open a tube as I wasn't sure if it would implosed on me and then after getting on my afce sheild, gloves and the tube was under several paices of cloth and in the box it came it. And then all I hear when it was penatrated is a slight sucking sound then that was it. I was pissed indeed.
If you look on the box of a fluro tube they say "contains no mercury"
Well all of mine do :D
Then again I think it's some barium compound that makes the "phosphor" inside the tube. Perhaps I should do a flame test? I also know it's not soluable leading me to think it's barium sulfate...

I start work on the new still on friday so you should be seeing some pics sometime next week
