i think that the only differences between the two version of the vapocane are the accessories (or lack of accessories) that come in each package. the vapocane B also has the letter B added to the glass heat exchanger part. i would be interested to hear what vapocane says about this.
i picked another vapocane B up during the xmas sale, as i felt i needed to give this vape another go. at the time i thought that this vape was probably the best bang for your buck you could buy - however, i haven't tried the gnome vapes, which became more well known soon after i ordered my vapocane B.
anyways, i had been really enjoying my glassvapobowl because of its screen pinches and quick heatup times. the vapocane B can deliver vapor as quick, if not a little bit quicker, than the gvb, and it tastes much better! however, its much easier to combust with the vapocane than the gvb when using the direct heating method.
screen placement is major issue with the vapocane. it takes some experimentation to find the perfect spot. the 'bowl', or intermediary joint between the vapocane B and the waterpipe really needs to be redesigned, or just designed in the first place! if only it was possible to mate the gvb bowl with the vapocane top...
tor:
i think it is possible to melt your vapocane if you heat it too long at the very tip, there are pics in this thread of melted tips.
how will you measure the temp of the vapocane in order to be to do your calculations? i would be interested in knowing if there is a way to guesstimate (with some reasonable accuracy) what temps your actively vaping at, other than by simply judging your abv afterwards.
tor;
What is the length of the conduct (input/grass sample) in your vapocane, so that I can try to make the calculus out ?
i don't understand this question.
