I've found a piece of 1 1/2" stainless steel pipe, sch 20...12" long, with stainless and coffee filters on one end works very well for this application. Use a #7 rubber bung, drilled to fit a 7/64" piece of tubing that the butane adapter goes in for the top end.
I'm doing some work trying to re-extract the active compounds from the waxes/budder to try and make a less expansive potent concentrate. I do this in a separatory funnel, takes multiple washes to get the compounds out and the solvent to come out clear. Lots of waxes remain. The remaining solution is a dark red color (indica was used), that is being reduced to pure oil. I'm curious if any members here have tried this.
KennewickMan Reviewed by KennewickMan on . Hash Oil Hey all I just made some hash oil. I never realized how easy it is. Butane extract. Here's a few pics. Entire process took about a hour. Requires a 12" piece of 1 1/2" diameter PVC. 1 End cap, 2 coffee filters or 1 doubled up. 7/64 drill bit. 3 or 4 cans of 5x filtered butane, 2 glass casserole dishes, 1, 13x9 and 1, 8x6. Rating: 5
