Types of Distillation
There are many different ways to perform distillation each with its own positives and negatives. It can generally be stated that purity comes at the cost of speed and so fast systems like a wiped film distillation usually aren’t for fine separation of components and slower systems like fractional distillation are generally for greater separation….
Purification by Altering Solubility (Winterization)
The process of removing waxes, fats, and lipids in general is often called winterization or dewaxing. When a solvent has several compounds with differing solubility you can remove the least soluble compounds by decreasing the solubility of the whole system. Altering the temperature, differences in polarity and agitation are ways to manipulate solubility and each…
How to Make Cannabinoid Distillate
Distillation is a common purification process based on the difference in boiling points between individual components in a sample. Simply put things that boil at a lower temperature are boiled off while higher boiling point compounds remain. In this case terpenes distill first are condensed and collected. Then cannabinoids distill after and are condensed, collected in…
Dewaxing SOP
Obtain 95% ethanol (195 proof). You can buy grain alcohol of this proof from certain websites. You can also buy liquor from a nearby store and distill it. Get a hydrometer (which reads alcohol percentage or proof). Do not under any circumstances use denatured alcohol. You can use isopropyl alcohol, but it will not be…
Terpene Extraction SOP
Process Summary The distillation of terpenes is a steam distillation process. Water is turned to vapor and is diffused through the plant material. The water vapor (steam) sweeps out the flask and carries terpenes along with it to the condenser. As the terpenes and water condense back into a liquid the terpenes will naturally float…
Purification Through Distillation
Purification requires the separation of compounds and distillation is a common purification process based on the difference in boiling points between individual components in a mixture. Simply put things that boil at a lower temperature are boiled off while higher boiling point compounds remain behind. As heat and/or vacuum are applied the compounds which have…
Improving Vacuum Levels in Short Path Distillation Systems
Many users of small Short-Path Distillation systems find they only achieve system pressure levels of 500-1000 microns when they first set up. This post gives step-by-step details on ways to improve system leaktightness, plus properly protect your Vacuum Pump so that deep vacuum (low pressures) under 100 microns can be sustained. Overview You must establish…
An Introduction to Distillation
Have you ever wondered by there’s morning dew or why your breath fogs a window? We often think as a vapor as steam, coming off from a boiling pot, but just like some hot soup the steam does not have to come from a boiling liquid. Liquids will exert a vapor pressure at temperatures well…
