While this is a very good topic of discussion... my one wonder is this:
Bleach, acid, and other highly corrosive chemicals are stored in near similar plastic containers, for years... and the plastic is fine. So are the mixtures we're
vaping even more corrosive than said chemicals? You have me curious mwa...
its not a matter of caustic or not. its a simple interaction between liquids and containers. You can store hydrochloric acid in a plastic container if it is of the correct type(take a second and think of the large lead-acid battery in your car, its made of plastic and sits for years because the acid and plastic cannot interact).
i think the point everyone is trying to make here is that the nicotine and or flavorings are interacting with certian types of plastic bottles that vendors use and using glass bottles would prevent this.
But...this does make me wonder about the fact so many
tanks, and cartomizers are made of plastic and i believe to some degree the filler that holds the liquid is a polyester blend or similar, what effect that might be having. and what if any alternative filler would tolerate the heat that cartomizers put out.
but my 2 cents on plastic or not, if you diy and store for a couple of weeks or longer yes go glass. If you order online and consume the liquid withing a week or two you likely have less to worry about, unless its premade in china or something. As opposed to being made fresh in the us. However glass dropper bottles are easy to wash, and extremely cheap. Go to any office supply store, Walmart's craft dept, or a hobby shop i bet you can get a 30ml bottle for less than a buck. Or they are also available online im sure for cheap also. then just simply pour your orders that come in into your glass bottles and dont worry.
people say :theres a reason nicotine is sent in glass bottles" yes your right, because in that pure form it is pretty darn strong. When diluted with pg/vg/ flavorings its fairly weak. but over time it can do the things you are saying to the bottles. then again if you are cleaning out your bottles with hot or boiling water and reusing them the heat from boiling can certianly weaken them.
