I am conducting a research experiment to analyze how e-cigarette (specifically JUUL) vapor affects the bacterial growth of a certain probiotic that is known to have benefits on oral health (a strain of Streptococcus salivarius). Essentially my plan after culturing the bacteria was to expose the bacteria to various e-cigarette vapor (of different flavors) to see how bacterial growth would be impacted, among other things. My question is, what could be an efficient and safe way to do this assuming that I have a somewhat small budget. I looked into vacuum chambers and bell jars but I might be putting too much effort into "extracting" JUUL vapor in a chamber or something just to expose the bacteria for just a short while.
