My friends brother showed me a device that he used to make a marijuana "tincture" using 190 proof grain alcohol as the solvent and it had a "Christmas tree" aluminum tower of decreasing concentric levels on top that condensed the vapor which dropped down into a container at the bottom. A light bulb was the heat source to vaporize the alcohol and the aluminum was designed to contain ice water for the condenser tower levels. My explanation is from memory back to the early to mid 70's but this the best I can do. Does anyone rember what it was called and is it available today?
