Eden Labs has the most relevant industry experience. The result is better customer service than our competitors. Not only does Eden Labs build superior, safer systems, we are also more knowledgeable and in the past have repaired competitor’s systems.
Absolutely. At Eden Labs LLC we pride ourselves on being able to meet the specific needs our customers. Your organization can collaborate directly with our designers to build the exact system you need.
With an appointment, training on the system is complimentary on-site at Eden Labs. An Eden Labs representative can also travel to your location for $1,200 per day plus travel expenses.
Generally speaking, most herbs are best extracted with a 50-50 mix of ethanol and water or vodka. In some cases a desired constituent is not soluble in alcohol or water and must be extracted in a more exotic solvent like chloroform or ether. If that is the case, you will need one of the Professional units that seal so solvent vapors don't escape. Ultimately, carbon dioxide is often the ideal solvent because it has different solvent properties at different pressures and leaves no traces or residues in the final product.
CO2 by itself is not a strong solvent, but by putting it under pressure and adding some heat, it gives an incredibly rich, concentrated and toxin free product. This makes for a healthier work environment and a healthier end product. Many of the companies we work with in the flavoring and nutraceuticals industries use the fact that their product is a Supercritical CO2 extraction as an effective marketing tool. People are becoming more and more conscious of how products are prepared and what is in them.
This depends on the material being extracted and the protocol being used. Generally CO2 is used to extract oils, so the oilier your material, the better yields you will have. We have quite a bit of experience with various botanicals and the pressure and temperature ranges needed to get the best results.
Our systems can run continuously with little maintenance. The materials which run through the vessel are soluble, so almost no cleaning is required. For example, when using the system to extract new materials, the only maintenance required is to run the system while it is empty in order to clean it out. Minimal maintenance required consists of cleaning the filter behind the pump every six months, testing the relief valves every six months, monitoring compressor oil levels, and occasionally replacing gaskets and O-rings. If you need to be certain there are no residuals, a steam generator can be used to flush the system.
There are no licensing requirements for the system or the solvents. CO2 is an inexpensive substance and each system only uses roughly 6lbs per extraction. Each system uses 70-80 amps of electricity per extraction as well.
Included in the cost of the system is an extraction system, a chiller, and two heating baths. An air compressor is not included, but Eden Labs does sell compressors separately.
At least 1.6 horsepower, though a 5 horsepower screwdriver compressor is recommended. Run time improves with more horsepower.
Low humidity and roughly 74 degrees Fahrenheit.
As dry as possible, a fine grind, with a light pack is best used in the extraction vessel.

Different herbs have varying sensitivities to heat. It is usually good to have some heat when processing herbs. Moderation is the key. Temperature ranges from 100-150 degrees Fahrenheit are usually ideal. All of Eden Labs equipment will operate in this temperature range and more. Many herbalists believe that herbs should be extracted at room temperature. If you want to follow this rule, a cold percolation unit, the Professional Round Bottom unit, or a mixing tank is the way to go.
Solvents are distilled out under gentle heat or gentle heat and vacuum or just vacuum if no heat is desired. This can be done because your solvents have a much lower boiling point than your extract. Therefore when heat or vacuum is applied to the extract infused solvent, the solvent begins to vaporize and rise out of the extract whereby it is collected into another vessel.
