Hmm not sure if I have any 91% laying around still might have chucked them, simple enough to go get some more though :)

Ive got a bottle of mint rubbing alchohol, smells like Listerine.

Use vodka :thumbsup:

Was just gonna say that. I can't remember what temp it freezes at but I can find out. Ever Clear has a lower freezing point but I just can't get any out here.

I use it with the Phantom Dual Wall setup at max LN2 temps it did freeze solid.

Here you go...

• Wood alcohol (methanol)
– freezes at -97.8° C (-144.0° F)
– boils at 64.7° C (148.5°F)
• Grain alcohol (ethanol)
– freezes at -114.1° C (-173.4° F) -- Everclear Alcohol? Something 180+ Proof
– boils at 78.5° C (173.3° F)
• Liquors:
– 24 proof liquor freezes at -6.7°C (20°F)
– 64 proof liquor freezes at -23.33°C (-10°F)
– 84 proof liquor freezes at -34.44°C (-30°F)
• Isopropyl Alcohol
– 90% isopropyl freezes around -90.0°C

That would be a terrible waste of perfectly good Vodka ???? :shock:

Does alcohol evaporate like mad out of your pot so you have to keep adding it?

Yea you just have to keep an eye on it

But we were adding very small amounts like a cap or two at a time

hmm interesting, with the Phantom I did not have to add any, maybe because the container is so big that I didnt notice.

Be carefull adding room temp alcohol to some thats -70c :ohcrap:

That makes for the best pics as the steam rolls across the rack ........:thumbsup:

Kinda erry looking and mad scientist like ........ :clapping:

I like acetone. Alcohol tends to gel, acetone doesn't. Just a matter of preference though, whatever works for the individual.
