Clean Butane Hash Oil Extraction: Vacuum Ovens Alternative

Following up with the original post about BHO extraction, some of our readers have suggested a few other alternatives (safer means of extraction) that I will be covering in the weeks to come.  I am all for smoking the good stuff but safety is always first.  So here is my vacuum edition of BHO extraction.

If you have the means and the money to purchase a vacuum oven, I suggest you do it if you want to smoke the cleanest wax ever. Vacuum Ovens can be a bit pricey especially for the good one and range from $1000 to $2500. Multiple websites such as eBay sell used vacuum ovens that are substantially cheaper (ranging from $200-$1000). Vacuum Ovens allow for even temperature control at low temps. Chemical duty vacuum pumps allow the user to insert his residue made by pushing butane through cannabis, and collect residual butane so that you may dispose of it. These types of pumps won’t be harmed by the butane and will last a lot longer that other type of pumps. You can also make large batches of shatter using vacuum ovens rather than other vacuum methods.

If you do not have the cash flow to purchase a vacuum oven, I suggest you at least use a glass vacuum desiccation chamber with a hot plate inside. Raising the hotplate temperature to 115F in the vacuum that is set at -29.9hg will leave behind a clear shatter when cooled. If your shatter remains sticky, you should purge it again. Small bubbles may exist in the end product but this is the result of not using a better purging mechanism like a vacuum oven. You should always smell your shatter to make sure there is no butane in it. A well prepared sharer will smell very good, and should serve as an assurance that no residual butane is left.
