I just hit 91.6% on this batch. I thought I had totally fucked up after I wasn’t paying attention and had crude shoot through the system and hit my cold trap.
Yea, that was fun, but I’m learning, so whatever.
I ended up taking that crude that shot through the system and putting it into a 500ml flask/mantle and just running it separately for practice. That subset hit 91.6thc/97total.
What is funny about that is it was just first pass cryo etho extracted crude.
No carbon scrub.
Old ass material from a failed farm.
An old SPD 1 short path from Summit with no frills.
I did put the e30 on that small setup which I think helped. Last time I ran that system with my Welsh and hit 87%. Putting on the e30 got me to 91%.
With the same setup on a 2L, I’m consistently hitting ~86%.
So maybe if I had a deeper vac for my 2L, I could hit 90+ on that too.
