Sox I don’t mind building/wielding that is what I prefer so if you want to help set me in the right directions on parts and meterials needed to make an Ss column or a closed loop. I don’t want to be using pvc but I am using it for the time being to keep up my regiment. My plan is to make enough for my closed loop and start doing my extracts that way. I have a friend up north who can get my stuff lab tested, I plan on testing a pvc run and the closed loop stuff to see how much solvent I have left in my product and to see if there are impurities.
Everyone that’s chiming in on pvc leaching into final product, before I made my dewaxing tube last night I’d winterize using alcohol and freezing it. To my understanding pvc doesn’t dissolve in alcohol and should precipitate out and get caught in the filters. I understand the amount leaching off can be to small to see, but they’re should be some kind of indication of pvc caught in the filter if it is dissolving it
