I have used it for my first distillations of DCM and acetic acid, it gets really soft at higher temperatures, especially when hot solvent condenses in
it, something leached out from the tubing, but well, I got what I needed in both cases, but the tubing was unusable after, it stiffened up. and the
products were contaminated.
Now, when I have the right glassware - I still prefer silicone tubing for any application. they are more expensive, but won't loose elasticity and are
more inert, I think.
