Of the following materials, which would be the best to use to connect the flasks -> condensors -> gas traps etc..
1) PVC pipe. (grey)
2) ABS pipe. (black)
3) Flexible tubing (steel/plastic mesh it looks like) from plumbing uses.
4) Regular plastic tubing from an aquarium store (1/2 inch or larger).
The temperatures would be less than 200C in the flask.
Opinions welcome.
Cheers,
Runne
