ISO oil. Can I purge further after iso drys?

[Canadianbaconbitz]

I'm new to iso but enjoying it. I am concerned this batch may have iso left in it as it's 3 plants of 4.5 feet tall plants worth of trim and bud in 1 litter of iso. I keeped reusing the iso over and over and went through like 12 jars of trim and popcorn bud.

Any options to purge any potential iso out ?

a heating pad under a vacuum chamber would be ideal but just the heatong pad is better than nothing,,, care don't burn it, unless its already dark... i wouldn't go much over 100f
