I have a few estate pipes that I bought and I cleaned out with alcohol and reamed out bowl. I just want to really sanitize it. I would like to make my own retort using a round 250ml volumetric flask. I also want to attach surgical tubing from the flask to the tube and from flask to the stem of the pipe. Anyone familiar with retorts please give me advice. I would like to use 1/4 inch thick surgical tube and was wondering if that would be ok.
