Hey CAPO,
I was under the impression that its more than a soxhlet. A soxhlet, I believe, runs solvent repeatedly through a sample for a total extraction, and would probably leach the chlorophyll as well if you used ethanol, thus would require a more selective solvent like hexane or something. To distill your solvent you need additional apparatus after the soxhlet. Receiving flask, condenser, and all the attachments.
I have an organic chem labware set and all the chems for isomerization, as well as Cannabis Alchemy :). Actually meant do some this week but I have a lot of oil to make and just haven't gotten around to it.
You can procure all the supplies with no suspicion via the hobby biodiesel industry. PM me for a link if you need it. Its cheap as shit too and a liter will last FOREVER.
You can save money on a vacuum distiller by using a aspirator that hooks up to your faucet. You can get a good vacuum and reclaim your solvent easilty enough. A good aspirator is available from
www.elementalscientifc.net
You can also remove most impurities with a buchner funnel and filter paper, used in conjunction with a side arm flask on a vacuum. I regularly remove all the contaminate particulate matter from my oil, pre-evap. You can use a regular funnel and filter paper as well, but you will be waaaaiiiiittttttiiiiiiinnnnnnggggggg a good long while for it to drip drip drip drip drip drip until finished. The buchner w/vacuum allows you to soak and evaporating in a matter of minutes.
I've used charcoal exposure, a quick quick rinse is best, as if you soak your charcoal in the solvent for too long it will absorb your cannabinoids as well.
Cannabis alchemy, which is basically the template for "Dr. Atomics Marijuana Multiplier" which is available for viewing and download from scribd.com
Hey Tex, whats your game on the lab glass, as I have a few connections :)
One thing to consider for sure before you go to all the trouble to do it is to perform a Beam test. The formula is available in "Marijuana Genetics", also on scribd, but its basically a 10% solution of potassium hydroxide (might not be hydroxide, I'll get back with you or look it up :)) in ethanol. Addition of this to a sample will turn the sample purple if non-THC cannabinoids are present. If there is no purple development, then it isn't worth trying to isomerize since there isn't anything to change. If there is purple, then the fun continues :).
Be safe and hope this helps.
