Solvent-free approach to high quality extraction

The analytical procedure for flavors and fragrances extraction from plants or spices comprises two steps: extraction by steam distillation or hydro-distillation, and analysis by GC or GC-MS. While the analysis step requires just few minutes, extraction takes several hours, using a standard procedure based on the Clevenger (1928 year!).
To address these limitations, Milestone has developed the new ETHOS X for the solvent-less extraction of natural products. ETHOS X utilizes a unique microwave selective heating mechanism. The internal water within the sample absorbs microwaves and heats up, distending the sample's cells and rupturing the glands and oleiferous receptacles. This process evaporates the in-situ water within the plant material to quickly extract the desired oils

-       Fast and solvent-free extraction

-       High extracts purity

-       No thermal degradation

-       No clean up

for Solvent-free Microwave Extraction (SFME)

The ETHOS X performs solvent-free microwave extraction at atmospheric pressure of fragrances, such as essential oils, in plant material. The method involves placing the sample in the microwave reactor, without any added solvent or water. A cooling system outside the microwave continuously condenses the vapors which are collected in a dedicated fragrances glassware. The excess of water is refluxed back to the extraction vessel to restore the in-situ water of the sample.

Once the essential oils have been extracted, they can be analyzed directly by GC-MS without any preliminary clean-up or solvent exchange steps.

High quality fragrances are obtained without residual solvents, contaminants and artifacts.
