if you use denatured alcohol you can just leave it in the cooler and place the back on tbe next morning ur doneā¦ acetone will eat the gasket in coolerā¦i havenāt took mine out in while just readd
i can not take credit for thisā¦
@Soxhlet taught me to reuse my cooling solvents, saves tons money

I agree. Denatured alcohol for the win. Itās the only thing I use in slurries now

i started w acetoneā¦its not worth using those dreaded ptfe envelope gaskets
and for what 7-10 more degrees?
ill stick w -70f. thats just fine for meā¦and i bet once uve dissolved about 30lbs dry ice into 3 gal D alcohol, and it stops bubbling and acts like sdding cubes iceā¦its most likely-78f then

I didnāt think HDPE was up for that.
The all knowing one suggests that draining after use is going to be important for longevity.
While acetone will not dissolve HDPE , it can lead to material failure. If you leave acetone in a Nalgene bottle for long periods, it will eventually develop horizontal (i.e. circumferential) solvent-stress cracks at the level of the liquid-vapor interface, leading to failure when squeezed.

yep guys another reason why denatured alcohol is winning
all knowing mighty @cyclopathā¦tell my good friends here what the temp difference is on proper dry ice slurry denatured alcohol vs acetone. 7-10? (maybe 12)got some literature to show these guys? i dont remember the exact number? thank you good sir!*

Iāve not had the correct tooling to answer that question for myself since learning that I didnāt actually knowā¦
Before I got here, I always though acetone/isopropanol/ethanol/methanol all hit the same -78C
Iāve cited sources here (somewhere) that put ethanol at -74C and at -78C. Either way it seems close enough that I use ethanol (denatured or terp saturated).
If using it as a circulated fluid, acetone has better thermal capacity (iirc), but that doesnāt seem relevant in a vat style chilling.
Edit: looks like it was 72C and I didnāt actually cite my sourcesā¦
