wine jugs have aluminum lids with paper liner, all jugs have some kind of plastic or rubber seal. I love the glass bottles with a ceramic top and metal release mechanism, but the rubber washers deform and deteriorate, so that's not good. is ptfe 2 the only suitable material? or is there a kind of silicone that's acceptable?
Everything i say is fictional, I just wanna be cool and fit in.

Depends what exactly you're using with any given material. If you know what reagents and solvents you'll be using you can check it out on a compatibility chart. I'll dig one out in the coming days if you can't find the link here on the forum - this isn't a new question!

Platinum-cured silicone is pretty robust for the most part. You can replace the rubber seals that you mention with silicone ones with a reasonable assurance of safety if it's just plain ol' lye and naphtha they'll be seeing.




β€œThere is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
