Ethanol extraction for cartridges.

Hash and Stuff Extraction

Hello. Help me out, if you can, please. Right now I live in Spain, I have a rosin press that I want to sell and buy the following:

  • vacuum pump( 3/4hp, 8cfm, 5Pa) ← Don’t really know what this means, tell me if it’s good enough
  • hot plate with magnetic stirring ( I think this will make my life easier when it comes to the first evaporation and mixing the terpenes)
  • flask + buchner 100mm + whatman filters(grade 5, 375 herzberg(what?) which are 90mm ← will this work with the buchner funnel?
  • vacuum chamber + heating pad
    I want to use hash as the starting material as it is pretty common around here. I want to do this because I believe it is going to be easier to sell cartridges than rosin( I would not be here otherwise)

Now for how I want to do it, keep in mind I’ve never done this. Place everything in the freezer for 48h -20 celsius. If I use 10gr of hash, should I add 100ml of ethanol? How many minutes should I wash it for? 4-10m? Will do 2 washes. Place back in the freezer for 12h, filter through than straight on the hot plate( is 70c too high?). Than in the vacuum chamber, here I don’t really know how to do it, what temperature and for how long. After all this will the end product taste bitter? Will I get close to 70% THC? Is it possible?

I’m sorry if this post is all over the place. I’m ready to learn, if you have any books or sources, please send them my way. Thank you very much.

If made from hash, and done quickly, your product should not be bitter. It will probably be fairly dark in color.

70C will also darken it, try 30C

I changed my mind, again, I’m just going to wait until I can buy everything without selling my press. I think I saw a post a while back, not here. That stated you can purge in a vacuum and get more of a oil consistency so you don’t have to cut it, it was something like 140f, don’t know for how long. My question is, under full vacuum 140f is way more than not under vacuum, right? So will this make you lose THC? I have in mind that graph from decarboxylation.
