Tubing for acetone
Hello people!
I need to get some tubing that can handle acetone without dissolving or degrading. It should be flexible and if possible transparent.
Im thinking of maybe polypropylene tubing, but im not sure if it will work well for continuous use.
Do any of you guys have any suggestion?
Best regards
Majvor

What temperature is the tubing operating at and for how long continually does it need to run? It looks like polypropylene should be fine for several
months to a year or two at RT depending on the source of the info.

The tubing will be subjected to some boiling acetone vapors, but mostly liquid hot acetone.
I want the tubing to withstand atleast 24h of use, but even more would be the best.
Thank you for the reply.

Yes it should last for at least a few weeks at that temperature. In the future, you can figure this out for yourself by simply typing "polypropylene
chemical resistance" into Google and looking at the first few results.

Trick I use for these questions I have my self, I go to google and type in "Material compatibility with acetone"
or what ever chemical you're using! Slowly you build up a large list of material compatibility.

PEEK tubing (the kind that's used in HPLC machines) will work fine, for an indefinite amount of time. It's more expensive (I found a site selling 5
ft. of 1/16" tubing for $30), but might actually be cheaper given that other kinds of tubing might degrade and need to be replaced.

What about PTFE tubing?
Too rigid or not as transparent as you'd need?
