Whether this would work depends on the boiling range of the solvent you're using. Heptane would be just about OK, mid-range naphtha would require more heat than that unless you're happy using reduced pressure. If, as by the sounds of it, the solvent vapours are passing through some kind of plastic hose then it's far from optimal and also effectively prevents use of reduced pressure.
Glassware needn't be that expensive and should prove to be endlessly useful to you.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. 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
