zOk so got lucky on a auction
And got this toy
Now what to do ?
Guess oil in solvent and freezing to -150C
To see what happens is one
butane and ethanol Will freeze but what happens to the oil
Any other sugestions ?
Take iT appart and figure out how they manage such a precise Ln2 assist cooling
Make a chiller coldtrap :rofl:
Who ever has a idea shoot see what we can do


Try extracting with subcritical ethane?


? Have to look that. Up
Why ethane seem a good idea in your opinion ? Yust curious


No real benefit other than low bp. Should be just like propane or butane extract.


polar ?
Vapor pressure at room temp ?
Smell ?


DME dymethylether is a gas low bp
Fairly safe but horibd


It is an alkane like propane, just a simpler one.
3.8453 MPa (at 21.1 °C)
Gas has no smell


Hmm see If i can get it i call praxair tomorow ask😀


I also wonder if dme will still extract pigments and fats at very low temps like what u can reach in your revco.


Worked a lot with DME in Giv E that a shot😀


Cant wait to see results of that :slight_smile:


What did you mean when you said DME is fairly safe but horibd?


DME has a higher flash point is less toxic
But is very polar making gunk extracts butextracts very Well strips of aa lot
