im doing a quick wash iso extract using cold iso. really basic just iso over material filter then evap w/ or w/out heat.Need a run down of your extraction process to best answer this question.
For me I'd simply distill the stuff over under vacuum. You may lose some terpenes/flavor doing this without a vacuum--and you may lose some anyway with one if you are not careful and do not know the identities of the terpenes in your strain, some will be more volatile than others.
Anyone doing ISO extractions industrially would benefit greatly from a rotovap imo--there just isn't a better machine for the job. Also because you're going to be using the reclaimed iso for further extractions purity should not be a huge concern. Any impurities you'll have will all be weed related. Now if you want pristine iso back, it complicates things a lot but if you're just trying to save on your solvent bill--I'd go distillation.
hey squigs and Gwolf . im really interested in solvent recovery systems. i have a good enough extraction process that im really happy with i just want to recycle my iso. what do you guys think would be the easiest method?
thanks in advance Deep
You could presumably build a "cold finger" system except instead of an open area below the finger you'd have a place to collect solvent. This might take some engineering ingenuity--not my strong point, see Graywolf :)
Still working on our solvent recovery under vacuum. Thus far, it is less than with a simple pot still, because we need more condensing area than I got running an ice water cooled Alhin and a Graham in series, with two ice water cold traps.
Sorry the new forum platform isn't letting me post pictures, but I will when that is sorted out.
If u got the cash you cant beat a rotovap for this.
Also worth noting that glass isn't the only rbf material used. There are PTFE rbfs out there and perhaps even some substrate affixed polar surfaced flasks. PTFE would be a close place to start.Except for the part about getting it out of the flask afterwards. Maybe start with a rotovape and finish in a vacuum chamber.
I'm not sure how these invalid links work? but they never work for me. do they work for others? links say invalid and that I got wrong page some how, but it's always this way 4 me w/ these links. any help is appreciated.I have included some crude pictures of the apparatus, please forgive my artistry (or lack thereof).

this thread went over my head pretty fast.
