Soxhlet Extraction & Recovery Systems
Soxhlet Extraction is a quantitative approach to plant extraction. It endures quick run times but ensures the highest yield and highest potency. In herbal processing, it makes a strong tincture in as little as 3-6 hours rather than the typical 3-5 weeks for a maceration.
These systems are the largest soxhlet extractors around. Built with alchemical philosophy in mind, these protect any heat sensitive chemicals all while making sure the volatile oils cannot escape. This is a hermetically sealed vessel that operates under vacuum. Vacuum distillations create lower boiling points making extraction safe and effective for you and your plant of interest.
In terms of hemp/cannabis extraction, this means it gets the full cannabinoid profile along with all the terpenes present. These are extracted and maintained at the plant's natural occurring ratios. Maintaining these natural ratios is important in maximizing the effects of the plant on the body. These extractors are built to maintain the synergy of the plant to the highest extent.
Three Systems in One
- Alcohol Extraction
- Alcohol Recovery
- Essential Oil Distillation (With Added Attachment)
Alcohol Extraction: This is done via soxhlet extraction. Alcohol is evaporated under vacuum and recondensed above the herb column with a condenser. Pure distilled alcohol is continuously flushed through the herb. The extracted oils collect in the bottom chamber while the alcohol continues to recycle through the herb. This method ensures you get a full spectrum extraction at the highest yield possible. The system is run until the resulting tincture is relatively clear as it comes through the herb column. At this point you have extracted almost all of the components from the plant.
Alcohol Recovery: Once the extraction is complete, the herb column is emptied of plant material and replaced. With the turn of a few valves, running the system will now recover the alcohol from the extract. Our extractors come with a water jacketed base to ensure you cannot overheat/burn your extract. The system now runs like a vacuum oven but will recover the alcohol used in the extraction process. This recovered alcohol can be used again for the next extraction.
Essential Oil Distillation Upgrade (not included): The system can also be configured to steam distill essential oils. With the purchase of our essential oil distillation head, you can fill the herb column with your herb of choice and run the system with distilled water under vacuum. The water will now evaporate and flush steam through the herb column. It is recondensed and separates the oils from the hydrosol. The hydrosol can continually be drained back into the bottom vessel or drained out of the system. After a few hours, all the essential oils will be captured in the separator where they can then be drained and used for aromatherapy. There are very few essential oil distillation systems that employ a vacuum. This ensures you cannot damage any of the volatile essential oils/terpenes. This system yields high quality oils not present on the market.
These extractors come complete with a vacuum apparatus and 1/4" hose outlets to hook up to a cold water source. The units come with a solid or jacketed base for your choice in heating apparatus.
You will need:
Cold Water Source
Hot Water Source or Heating Element for Base
These units are built to do soxhlet extraction under vacuum, and can also be used to recover the alcohol out of the extract.
We now offer custom built ice machines for use as water coolers.
Low tech methods can be used to run the condenser such as an ice water bath or simply hooking it up to facet/sink. However, keep in mind the colder the condenser the better.
A step by step instructional manual is included with limited consultation on running the system.
Please Note: This is not an automated unit. An introductory distillation course is necessary if you have never used a soxhlet system before.
Lead time is 1-2 weeks depending on stock.

Buyer assumes all responsibility of using the extractor. Limited consulting on the system is available. There are no returns on extractors.
These Ice Machines are converted into water cooling systems for use with all our extraction systems. These provide the cooling watts needed at a quarter of the price of most lab grade chillers.
This is a complete water heating system that comes with a hot water pump to hook up to our Soxhlet Extraction System or ERS Extraction System.
1440 watts of heating power
This can be added to any soxhlet system to enable you to distill your own essential oils. With this attachment you can do anything and everything when it comes to herbal extraction.
Comes with an extra base that is not water jacketed to fit on the bottom of your soxhlet extractor.
