| Frequently Asked
Questions
I need a custom design for a specialized application. Can Eden Labs accommodate me?
Absolutely. At Eden Labs LLC we pride
ourselves on being able to meet the specific needs our customers.
Your engineers and chemists can work directly with our designers to
build the exact system you need.
What is the best solvent to
use?
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 up 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.
Will heat damage my herbal extract?
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
products will operate in this temperature range. 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.
How are solvents removed from the extract?
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.
