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...

The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
