Distillation is the final process in the refinement of cannabis extraction – distillation uses vacuum pressure, steam, and heat, to manipulate boiling points so that compounds are subjected to much cooler temperatures when they pass through. Through this process, volatile compounds are separated by their weight and boiling point, leaving less volatile and undesirable compounds behind. An extract can even be passed through the distillation process multiple times in order to create an increasingly pure substance.
The terms residual solvent and residual solvent analysis get thrown around pretty regularly in the extraction industry. Today, we’re going to break down: What that means How [...]
