Supercritical Fluid Extraction of Cannabis

I just right clicked on your thread title and let The Eye of Sauron (Google) find this:

and this

http://en.wikipedia.org/wiki/Supercr...carbon_dioxide

about a year ago i spent a bit of time researching this and came to one basic conclusion, it is impossible to find an inexpensive source for this equipment. Even if you are able to lathe the parts yourself, you would still need to buy the high pressure pumps and heaters. then you would have to consider the extreme pressures you will be working with, if you do not have the means to set up a secure and safe laboratory it is very likely you could kill yourself. it may sound strange but a butane or hexane extraction system would be safer, if the right precautions are taken. if you do decide to go forward with this i recommend you research the method used to extract the caffeine from coffee and the essential oils from lavender. it will give you a good idea of the basic process. there are plans out there for "bench top" systems, but even those start at well over $1000 to assemble and would never provide enough to make it worth your while. dont mean to be a nay sayer, just sharing my experience.

Talk to Hobbes. Have a look at the thread, it's a hell of a read. Ask him about his subcritical fluid extractor.

My advice though, wait til after December 26th to ask him.

For those who are unfamiliar this process uses C02 at low temperatures (when it becomes liquid) pumped under pressure through a pressure vessel with the sample in it to do the extraction. It can be combined with other solvents or used alone.

I'm trying to rig up an inexpensive system that would process cannabis. Is C02 sufficient to do the extraction or do you need an additional solvent as well? Where can I find the equipment? I know about Eden Labs but they want 70.000 for a 20 liter unit. I think I can piece it together cheaper. Any information or ideas?

yeah you can hit me up for a scfe cheap. im the 1st youtube video showing it done w pot. 420 honey oil extraction co2- youtube.

well i hate to tell you your wrong. i found a way to get around the hefty price tags by avoiding it being pumped a liquid. huge 60:1 pumps made it impossable for individuals to extract w co2. my method uses solid carbon ice packed by hand, then pressurized to a liquid or scf. anyone interested should check out my vid, then hit me up.

and tell me if that would work for a supercritical co2 extraction chamber.. I have never built one so it is just speculative at this point...

I think I was looking for this very sort of thing not long ago, if it looks promising to some of you experienced guys I might give it a try...

I would love to check out your video!

I also am looking for an inexpensive Supercritical Fluid Extraction using CO2. Did you have any luck finding what you wanted? Do you have any suggestions?
