Iso goes hella quick. I understand why you would jump to it as i think most of us had the conclusion and it could be efficient maybe but in the legal setting where we were pumping large volumes you will end up having to refil way more iso tanks than you would N
I’m thinking of switching to is as I’m hoping less would get frozen in the material column. I dump the ice out and run hot water through the columns after and recovery out of the top when I’m done the column.
Does it gel up around -50 like n butane?
Also you’re saying I would lose more per run than regular n butane?
I found a soak helped a lot. First run with no soak was at 15% . Then tried soaking got 18-20% for the rest of the runs except for 1 that hit 22%. (last seasons outdoor). I did between 20-30 minute soaks.
And idk actual temp, but everything (tank, injection coil and column) was prechilled with di
Now you got me wondering how my yeilds would have been with N… Lol
Yeah indoor is hard to beat. Best I ever did on outdoor was 18% and it was 6 months old and not stored in a freezer… best cherry terps I’ve ever smelled
Isobutane purges super fast in relation to nbutane, which is nice when your ambient humidity is high.
Isobutane with soak times and ~11:1 solvent-biomass ratio has given us great results on fire indoor 18-23% thca dry material.
I don’t like to soak when running fresh frozen so isobutane heavy blends make FF logistics challenging.
We really get the best results running fire material, cured or FF with cold nbutane.
I’ve ran a 70/30 blend for a couple years then switched to straight butane which I prefer.
I’m guessing in conclusion n butane requires less solvent to material ratio for the same return. So any added recovery speed from isobutane could potentially be lost by the need to run more solvent or less material per run.
