Here's a few pics of a glass vaporiser, currently flame operated, improvised from labware.
Fully assembled:
The pieces:
So, we have a 500mL sidearm RBF, a 200mm air condenser/column, a sidearm adapter and a thermometer/tube adapter. The small glass tube is not used in the heating operations but does come in handy now and again:
The heat diffuser, made from coiled-up fine copper gauze:
This can be removed with the help of the screw cap when hot... The flame is directed onto a smaller button of coiled-up gauze.
Holder for matter to be vaped, a sort of thimble, again fashioned from fine copper gauze:
The side arm acts as a carburettor.
It's highly effective but the metal heat diffuser ought to be replaced with something more inert.
Yes, the glassware was very clean before use...
