ETHOS X For Environmental

Advanced Microwave Extraction System for Environmental Laboratories

Microwave-assisted solvent extraction offers superior lab efficiency in the determination of organic pollutants with microwave green extraction technique. Typical applications include chlorinated pesticides, semi-volatile organics, PAHs, PCBs, chlorinated herbicides, phenols, organophosphorus pesticides, dioxins and furans.

Designed by you. Developed for you.

Determination of organic pollutants in environmental matrices is a common task for thousands of laboratories worldwide, as it leads to controlling and protecting our environment from high levels of contaminants. This analysis is often done to evaluate the effectiveness of a remediation process, to assess the contamination in waste, in waste landfills and for general environmental monitoring. Therefore, every day environmental laboratories deal with several challenges to ensure high quality data and fast turnaround time while maintaining their competitiveness.
Extraction of pollutants from solid matrices is often performed with techniques that limit the productivity and have high running costs. Many laboratories still use the Soxhlet method that was developed in 1879!
Milestone listened to the needs of environmental laboratory professionals by developing the ETHOS X with the fastEX-24 rotor, which allows for simultaneous extraction of 24 samples in 40 minutes with minimal solvent usage. By using large volume disposable glass vials, the fastEX-24 rotor simplifies handling and allows to achieve lower detection limits.

Achieving lower detection limits with higher sample amount.

The ETHOS X with fastEX-24 rotor extracts up to 30 grams of sample with minimal solvent volume, helping analysts to accomplish their tasks.
The Milestone fastEX-24 rotor uses disposable glass vials, eliminating the need for cleaning and the possibility of memory effect between different runs. The 100 mL vials can accommodate the extraction of a large sample amount. The easy to handle and affordable cost of the vials leads to high productivity at a very low running cost.


The ETHOS X operation is simple: samples are loaded into large volume disposable glass vials with appropriate solvent mixture, placed into the Weflon vessel and sealed. The unique Weflon material ensures homogeneous heating in all vessels, therefore increasing extraction efficiency even when different matrices are processed simultaneously, which enhances the lab’s workflow. The accurate contactless temperature sensor ensures full control of the extraction cycle in all positions and displays realtime the temperature of all samples on the dedicated user interface. The 100-mL glass disposable vials accommodate large sample amounts of up to 30 g, enabling lower detection limits with minimal solvent volume. In addition, the memory effects often observed with polymer vessels or with other technologies are eliminated. This is a valuable feature for trace analysis of challenging species such as dioxins.


Although new extraction technologies have been developed in recent years, they have fallen short of addressing the needs of environmental labs. The ETHOS X with fastEX-24 overcomes productivity limitations of other conventional approaches by enabling the extraction of a large number of samples in a single workday. Other technologies process one sample at a time sequentially, requiring long extraction cycles. The ETHOS X simultaneously processes 24 samples in only 40 minutes and eliminates cleaning steps by using disposable glass vials. The graphic below compares the typical daily productivity using the Milestone ETHOS X, Sequential Pressurized Liquid Extraction and Soxhlet.


Data quality and reliability are key features for environmental labs. The ETHOS X with the fastEX-24 rotor provides fast, accurate and precise analysis. Weflon vessels allow to simultaneously process various matrices ensuring optimal extraction efficiency. In addition, the unique design of the fastEX-24 rotor with its large volume disposable glass vials (100 mL) eliminates cross contamination and memory effect, providing reproducible results.


Several official methods describe the use of microwave closed-vessel technology to enhance the extraction efficiency of organic pollutants, such as US EPA 3546, ASTM and other national methods. The top-right table reports the typical conditions used in US EPA 3546. The ETHOS X with fastEX-24 further enhances the performance of microwave technology for the extraction of water-insoluble or slightly water-soluble organic compounds from soils, clays, sediments, sludges, and solid wastes. In fact, the ETHOS X with fastEX-24 can be used for solvent extraction of chlorinated pesticides, semi-volatile organics, PAHs, PCBs, chlorinated herbicides, phenols, organophosphorus pesticides, dioxins and furans.


The competitive nature of the environmental analysis market requires today’s laboratories to have innovative solutions that provide faster turnaround times. With throughput capabilities of 24 samples in only 40 minutes, the ETHOS X with fastEX-24 reduces overall analysis costs by increasing productivity. The combination of lower solvent volumes, less maintenance needs, and the use of inexpensive disposable glass vials decreases the cost per sample to enhance your lab’s competitiveness and profitability.


Elemental analysis by atomic spectroscopy is a standard analysis in environmental laboratories. The ETHOS X enables digestion of environmental matrices such as soils, sediments, wastewater in full compliance with official methods like US EPA. Several options are available to match the laboratory requirements.



The analysis of organic pollutants in environmental matrices, such as soils and sediments, includes the filtration step, after a solvent extraction process. The conventional approach to filtration involves old-style apparatus that reduce the lab workflow and occupies valued space in the fume hood. The Simultaneous Filtration System (SFS-24) overcome these limitations, improving the lab’s productivity and reducing the fume hood space requirement.
