I use glass vinegar  bottles with narrow necks  with plastic or metal cap  that  have a coating that will resist light acids...

Using canning jars is an easy way to expose  your self to ..[more vapors] from the solvent faster because the jar mouth is much larger..

In my early  days i tryed to use canning jars with sealed metal coated lids but got tired of exposing myself to  fumes  and once found out how easy it is to knock over the jar...

Use glass narrow necked bottles and a pipette to transfer dmt rich  pulls to another vessel..and while doing this i use a small computer fan close by to direct  vapors safley  out the window ...but before hand i make  SURE..! no one is out there  to notice the vapors!

If needed.. using a  vapor mask is advised..always remember solvents are flamable!
