What can be done with these glass columns?

tandpasta - 4-7-2016 at 07:58

I found these large glass columns, and I was wondering what one could do with them, besides maybe turning them into abusrdly large chromatography columns.

They are 50cm high and almost 10cm in diameter. I don't think they're made of borosilicate glass, though the walls are quite thick, 2,7mm. And they're open at both ends.

What would you guys do with them?

On a whim I bought something similar, then asked a similar question,
the options that I liked most were;
. build a Jacob's Ladder inside, collect the NOx as HNO3
. build a tornado in a tube, e.g. https://www.youtube.com/watch?v=vy7zbPiK9bE

.....I would make some chromatography columns that i can use with my alkoloid extracting project .......if you can't use them send them to me , i live in Mexico i will pay for postage......solo

Sulaiman, do you have some theoretical material on what a Jacob's Ladder is exactly? Google and the search here doesn't explain much... What I got so far is that you can make sulfuric acid from air, using electricity?

solo, shipping to Mexico would be at least $150 haha

aga, sorry if you're having a bad experience. Maybe it's time to upgrade that 800x600 monitor. I shrunk the photos down to just 900px wide.

Mini barking dog. just use methanol or ether if you have a death wish and some ppe. I do methanol in tubes all the time. never tried ether so i cannot say what would happen

Those tubes are one the things that you see and go, they look really useful! Then spend many years with them in cupboard figuring out a use lol. Great find but no idea what i would use them for, if it helps i would have brought them as well.

Flash chromatography?

Cool aquarium?

they would make great bass marimba resonators.

They look like borosilicate to me.

Typically borosilicate is green on the ends, quartz is white, and flint glass is black. That's what the glassblower showed me one time in college.

One option for my giant glass tube that I am considering is as a gas scrubber,
Sometimes I have been unable to absorb or neutralise 'nasty' gasses quickly enough with 'normal size; glassware.
But a large, safe, accesible permanent space is required :(
Ideally any fan could be used to pull air as any 'nasties' will be absorbed/adsorbed/neutralised...
... just dreaming ..........

EDIT: I think that the green of glass is due to iron impurities

Those barking dogs and Jacob's Ladders look tempting. But I don't want to die (yet).

Sulaiman, I don't think that the green indicates boro either. I've seen lots of window panes with a green tinge, and those are definitely not boro.

I've been looking at some chromatography literature, but I never see columns that are this large in diameter, would it even be practical? I'd also need a huge amount of chromatography grade silica (expensive!).

Maybe a gas scrubber is a better idea. Or maybe a ball mill with glass beads, does that sound practical to you guys?

On the other hand, a huge soxhlet-type device is also a possibility. That'd allow me to do plant extractions on quite a large scale.

Gas scrubber or tube furnace makes sense. Not good for chromatography, hard to seal an open column like that, better to just use a real column, they are cheap. Ball mill sounds like a way to make glass shards. Green glass does mean iron impurities. If it is quartz, then 254 nm light will pass through it and make a TLC plate glow, simple lab test. That would be worth a good bit if quartz. I have seen similar tubes also, not sure what they were for.
