For those of you against glass jars with a plastic ring...

[sleepermustawaken]

You could sandwhich a piece of aluminum foil in between?

I tried it without the foil but the naphtha loosend the plastic rings untill they fell right off.

You assume I live in a western society, probably in some suburbun town with a local home depot that I can redily buy anything I wan't in. Sometimes you can't get what's ideal and have to work with jars with plastic liners, in that case then anyone can look at my post and see that worrying excessively about plastics is probably OTT.

Also, it isn't that hard to just dump powdered dmt-fumarate in a whole bunch of acetone and viola... clean dmt.

I haven't changed any techniques that would reduce yield or change the taste or make it untrustworthy?

No need to get defensive, brother/sister. We are just trying to help. Glass is better than plastic. End of story. If you can't get glass, well, okay...do research get the right plastics and you'll be fine.

Best of luck to you, truly

That's not even going to break open the crystal structure and let anything out. Are you kidding me? All that will do is wash the plastic off the outside of your crystals.

If you have plastic in your crystals I would recommend something more like this:

" in that case then anyone can look at my post and see that worrying excessively about plastics is probably OTT."

IT IS a problem. There could be plastic in the resulting product that now needs to be cleaned out. In my book that is a BIG problem because I respect my body and don't smoke plastic and I also respect others and don't want them ingesting plastics. It's clearly unnecessary to ingest plastic unless you are so impatient that you must extract your spice right this minute and can't afford a glass jar and a wooden spoon. If that's the case you should re-evaluate your priorities right now because you might just be concerned with all the wrong things.

It's cool you want to contribute but giving people at least one extra cleanup step to do, not to mention converting to fumarates in the first place just to use plastic... SMH

Glass is better than plastic. End of story.

Clear and simple answer. Glass = zero chance of contamination. Plastic = possibly unknown level of (possible) contamination.

Yes, it may be a minute amount of plastic that ends up in the final product. But the killer is simply not knowing. If you're okay with that kind of uncertainty, that's your choice. It's just that most of us are not comfortable with that.

[...] I was reading through the MSDS for a particular brand of naphtha & noticed a warning I have not read well enough to notice before. Something along the lines of exposure in an improperly ventilated area may cause permanent central nervous system changes.

Hexane

Central and peripheral nervous system damage.

coming back to the aluminum thingie... is it ok to sandwich aluminium in the lid of my solvent storage containers... leaving solvent in the glass containers with plastic seals completely destroys the seal from the fumes... and i bet plastics leachs into them... so i put some foil first and then the lid...

im only talking for storing solvents... not lye or acids...

I just put the lid on upside down... Seals up great and doesn't melt in xylene, etc.

So I checked on a couple things so you don't have to. Nalgene labware plastics are not recommended with bases if the temperature exceeds 248F. I believe your exothermic reaction will go a bit hotter than that. As far as ABS plastics go, naphtha is a no no. I didn't check Xylene but you can bet that if naphtha melts it Xylene will too.

Lolwut? Maybe if you dump it all in at once... But if you add the base incrementally and allow time to cool between additions (which would be the safe way to do it), the temp can easily be kept far below that. I've never boiled a solution by adding lye, that would be a totally unsafe way to handle things.

Lolyeah, because what tek ever told you to let the solution cool between adding base? None. My intention here is harm prevention and I bet a lot of people are having very hot exothermic reactions. Hats off to you my friend for safety first.

Even single lye prills will cause overheating and a very high pH locally, so stirring is always important. I advise people to dissolve lye in a stainless steel vessel, as it will not shatter like glass may do. Always wear safety goggles and gloves.

Although I am still relatively new, I have tried to research ad nauseam about anything that could possibly come into contact with any solvent that Im using which could leech chemicals into it. I don't understand why it's so acceptable on here to use Saran Wrap as a cover while doing freeze precipitation clearly Saran Wrap is not a good choice for a cover. I also realize that full glass containers are very hard to find that fit tightly enough. Another thing that concerns me is the Pyrex trays with plastic lids (blue\red usually) that people recommend using DO NOT use these lids as you will almost definitely have these impurities in your final product. Now if someone could answer the question if it is safe to use foil? I do know they spray one side with something...... Still looking that up although I'm fairly sure naphtha and foil is not a good idea.

 

[downwardsfromzero]

If you're concerned about a coating of 'something' on one side of your foil, you could always wash it with naphtha before use. Just keep it away from acids and strong bases.

Domestic grade aluminium foil is (one would hope) considered food grade, so anything coating it is likely to be minimally harmful.

I like to use glass and stainless steel wherever possible as they are durable and easy-to-clean.

This. Corroded rings on mason jars are pretty much standard. Plus I've had several jars simply crack apart at the bottom while doing warm water baths.

Borosilicate glass and stainless steel all the way wherever possible. I can't emphasise enough the value of investing in good glassware (funnels, beakers with nice spouts, pipettes etc) and stainless steel pots.

 

[pete666]

Best choice I know of

 

[loph]

If possible you can purchase pvdf, ptfe or peek films and use the same way as the suggested aluminium foil. Works great as long as the film is not too thick, since they are not very elastic.

glassware is everywhere. liquor bottles strong , food grade. candle jars from large retail store- cheap and remove plastic ring or invert lid....all glass.
