Hey /sci/ how would I go about cleaning unknown chemicals out of a Buchner funnel/flask? I've got two of of pic related, and a few other things I came across.
>>
just dump it down the sink who cares
>>
>>8000343

bleach and a metal brush

do so while wearing eye protection and gloves in a well ventilated area as well
>>
>>8000343
3 parts conc H2SO4 : 1 part 35% H2O2

I use this stuff in a turkey baster to unclog my drains.
>>
>>8000348

depending on what it is, that's a bad idea. Dumping any sort of biochem experiment down the drain means you'll get something growing in your pipes. Which is bad.

In these circumstances, the best method of disposal is dumping the liqoud in question into a ziploc bag filled with cat litter, which will absorb it. Then it can be safely thrown away to become someone else's problem
>>
>>8000343
dilute it strongly with water so all thinkable limit values are ok

no nitric acid, no contact to skin,...
>>
>>8000357
I know it's not biological. It's from a factory, and may have been used to make meth in some way, found ammonia and broken batteries in the area.
>>
>>8000353
Come on, are you even trying?
>>
>>8000367

what, your'e not scavenging this from a dumpster are you? If you are then it probably got thrown out since they weren't able to clean it
>>
>>8000371
No, not from a dumpster. The factory shut down, and they were cleaning it out for the longest time, this and a few other things were still there, in a closet when I went there.
>>
>>8000367
found ammoia there, mk, then protip again: no nitric acid
>>

Also found this vacuum pump that holds at 600-625mmHg
>>
>>8000384
piston pump, i guess limited by vapor pressure of oil, so you mean it is able to do a max of 625 torr pressure difference

could be worth something if its still working proper
>>
3M Green pad cleans most stains off ceramics including glass.
>>
>>8000409
Thanks! Any idea how I'd clean the funnel itself? Or should I just buy another?
>>
>>8000367
>>8000371

This, if it was used to make meth, it was probably used to make hydriodic acid, in which case that is polymerized crap you'll have to scrape and chisel out.
>>
If it doesn't come off with any standard solvents, it most likely wont come off during any typical reactions you run, and you wot have to worry. However if you're that concerned you can soak it in sulfonic acid for a while...

Progress.
>>
>>8000343
Why not obtain an IR/NMR spectrum to identify each compound? Then dispose of it properly once you know what it is.
>>
>>8000443
What vacuum pump do you use for your filtrations?
>>
>>8000523
I'm not in a research field, and am more or less sitting here with a pile of glassware and assorted machines. I have a decent autoclave, so worst comes to worst, I can sanitize. That's about it.
>>
>>8000351
>>8000353
DON'T DO THIS IT CREATES MUSTARD GAS>>8000409
>>
>>8000343
Base bath for a few days yo
I'm a fan of the KOH/IPA varieties
If still not clean, piranha solution
Make sure you've rinsed with lots of water between base bath soak and piranha solution treatment
Add piranha solution a few drops at a time, swirl, repeat till clean.
>>
>>8000343
You will probably die, but try HF.
>>
>>8000901
No it doesn't...? It's piranha solution. And I'd do that if I had a fumehood right now, but that's not happening till the first Saturday of the next month.
>>
>>8000607
Isn't there a chance that your unknown chemicals could ignite or explode if you put them in the autoclave?
>>
>>8000353
>>8000353
What happens if you mix concentrated acid with a strong oxidant?
>>
>>8000343
Just dump some fucking acid in there.
If that doesn't work add some organic solvents, they smell real nice.
>>
>>8001334
That's piranha solution, it literally eats metals
>>
>>8000343
You should try water, alcohol, acid, DMF, concentrated sulfuric and nitric acid. Be carefull with the last two, it can react REALLY fast. Read about conc acids first.
>>
>>8001360
Also I use DMF/methanol/conc HCl 2:2:1 in case of unknown shit on glassware. Just let it stay for day or two and then wash with water or anything.
>>
>>8000901
Might as well add a frog to that dumb post.
