Ugh.. I remember trying to distill some goo in a flask, I got tired of messing with the small volumes and just attached a LATEX HOSE to a RUBBER STOPPER and stuffing that into the opening of a 1gal metal can of stripper, which was placed in a larger pot of water on the stove. Needless to say the DCM was contaminated by the tubing and had a khaki color to it, but that was much more easily distilled in a flask than the goo. I found that empty hydrogen peroxide bottles hold DCM just dandy, AND they fit right onto 24/40 joints!
The latex tubing was coiled through a bowl of icewater. I distilled approximately .75l this way. The reason I used the latex tubing rather than fitting my still head to the can of DCM was that I couldn't get the glass to fit, but I had a 1-hole stopper that fit perfectly. I should have used copper.
