EASY-TO-ADOPT MICROWAVE EXTRACTION SOLUTIONS
Superior efficiency in solvent extraction
Sample preparation is the least evolved and most error-prone step in chromatographic analytical procedures. Many laboratories still use the Soxhlet method that was developed in 1879.
Microwave-assisted extraction uses closed vessels to heat the extraction solvent above its atmospheric boiling point. Working at elevated temperature increases the solubility of the analyte of interest and decreases the solvent viscosity, leading to more efficient sample preparation and lower extraction times. Microwave extraction is selective, fast and produces more accurate and precise results than other methods.
Typical applications of microwave-assisted solvent extraction include organic pollutants from environmental matrices, fat determination in food samples, contaminants from food and extraction of additives from plastics.

The new Milestone ETHOS X
FAST
Microwave extraction is completed in just few minutes. The Milestone ETHOS X can simultaneously process multiple samples in a matter of minutes. Microwave assisted extraction uses closed vessels to heat the extraction solvent above its atmospheric boiling point. The elevated temperature increases the solubility of the analytes of interest and lowers the viscosity of the solvent, allowing it to better penetrate the matrix.
EASY
An important feature of the ETHOS X is that it easily adapts to existing extraction chemistry. This is accomplished through the use of a unique, patented material, called Weflon. Without Weflon, extractions could only be performed with polar solvents (Acetone, Methanol, etc.) or mixtures of polar and non-polar solvents, because non-polar solvents are not heated by microwaves. Weflon eliminates this problem by acting as a coupling agent. Weflon stir bars are heated by microwaves and they subsequently transfer this heat to the non-polar solvent.
ECONOMICAL
Lower solvent usage reduces the costs of solvent purchase and disposal. Microwave extractions are carried out in closed, sealed vessels. The matrix is constantly bathed with hot solvent in a self-promoting reflux action with no loss of volatile analytes or solvent. The use of closed vessels, with the speed and efficiency of microwave heating, allows extractions to be performed with significantly less solvent, without sacrificing accuracy or precision. The simplicity of the microwave technique reduces the attended labor time and increases overall productivity.
