Well...In my country are normal glass destilation setups quite costly like 150 euro, so I would like to improvise one myself...i would probably make it out of copper piping or some metal like that, but...I wouldn't like some impurities in my destillate (if i was destilling something that would react with the metal..)..so i would like to know if somebody know of some cheap very inert thing with which i could coat the inside of the tubing?
Thanks for the answers
