If you got $5000 in extraction equipment, closed loop, recovery, etc...
This post is kinda not meant for you...
This is for people making oil at home, and trying to do it safely... You are talking about lab-processed.
Yes, if you have several that kind of setup, even at home... its still a lab.
Thats like saying "You don't even need a vac chamber"
No... you just need a closed loop system, cold trap, recovery tank, vac pump (wait, what?? But you just said...)
You either spend $200 on a chamber/pump setup, and purge the fuck out of it for days... or spend a few grand, and make the process faster, and more ...well... fuel efficient.
