Our method of cannabis extraction is through the use of a tetrafluoroethene (TFE), R134a, as a solvent. R134a by itself is often used in aerosol products for drug delivery. Products which are extracted using this method are called post-winterized full spectrum oils; the level of wax present in the extract right off the machine is usually less than 5% or even less than 2% in most cases. The process is very similar to CO2 extraction: both methods utilize a gas for extraction and liquefy it when it is in contact with the material.

R134a extraction is performed at low pressure and room temperatures to strip the natural oils from the raw cannabis products in a closed loop system. The gas is slightly pressurized, then driven through the plant material and recovered in a separation tank leaving the full spectrum oil behind.  R134a is safe for human health, nontoxic, FDA approved and qualified as GRAS (Generally Recognized As Safe) under FDA standards. It has also been approved for usage as a solvent in the EU, by EC Directive 2009/32.

R134a extraction is the method Truextraction™ has pioneered after years of diligent research and prototyping.  We have effectively isolated R134a to be the most appropriate method of primary plant matter extraction. As a primary extraction method it only draws out the terpenes and the heavier resins – in this case, the cannabinoids. We have applied this method to over 150 various herbs before we applied it to the cannabis industry. We’ve used ethanol, SHW and steam distillation equipment, but utilizing R134a extraction solvent in cannabis production is the preferred extraction method, because it is simple, safe and scalable.
