Subcritical and Supercritical Extractions: Tailor to you specific production needs.

Creating CO2 vape oil from an Apeks Supercritical extractor is usually done via a terpene run —  a short, 20-minute run at subcritical parameters (low pressure/low temperature). The extract is harvested and either used just as it is, or set aside to be added later to a subsequent extraction. Then the processor can continue a subcritical run to extract more oil. This oil will be slightly darker with fewer terpenes than the initial terpene-run oil but will contain greater amounts of THC. Highly concentrated, it can contain as much as 80% THC. Processors can choose to add some of the terpenes from the first run into this extract to give it the smell and flavor that it lost. Finally, the system can then be set to supercritical parameters (high pressure/high temperature) to extract the rest of the oil. Supercritical extractions also pull waxes and lipids from the plant material which will require a common post-processing technique known as winterization to remove them.

3 basic steps to winterization.

  1. Mix thoroughly the raw extract with 200-proof ethanol. Then place the mixture into a lab-grade freezer until it reaches -35 to -85 degrees Fahrenheit. The waxes and lipids will separate and harden; the oil and ethanol will remain in liquid form.
  2. Pour the cold ethanol extract through filter paper inside a Buchner funnel into a vacuum flask. The solid waxes will stick to the filter paper so that only the oil-ethanol mix will filter into the flask.
  3. Once the waxes are removed, distill the ethanol off of the solution using a rotary evaporator. A rotary evaporator works best to separate the ethanol because it uses a large surface area and low-temperature heating under a vacuum which preserves the flavors in the extracts.
