Quattro ESEM

The Thermo Scientific™ Quattro environmental scanning electron microscope (ESEM) is a versatile, high-performance instrument with a field emission gun (FEG) for excellent resolution and beam current stability.

Three vacuum modes (high vacuum, low vacuum, and ESEM) provide the flexibility to accommodate the widest range of samples of any SEM available, including samples that are outgassing or otherwise not vacuum-compatible. Quattro offers a choice of detectors that include directional backscatter information, STEM and cathodoluminescence for tunable and real color contrast. All Quattro ESEM systems can be equipped with analytical capabilities, such as energy dispersive x-ray spectroscopy (EDS), wavelength dispersive x-ray spectroscopy (WDS) and electron backscatter diffraction (EBSD) coplanar with EDS.

Quattro’s unique architecture is supported by a help function (User Guidance) that not only instructs, but also directly interacts with the microscope. Quattro supports undo/redo functionality, scanning presets, column presets, easy camera-based navigation, SmartSCAN™ and drift compensated frame integration (DCFI) to boost productivity, data quality and ease of use.

Quattro ESEM for Materials Science

The Quattro ESEM now includes even more flexibility for modern materials science research, addressing the demand for greater visibility into the structural properties, elemental distributions, and dynamic changes of materials in their natural state. New accessories for detection, automation and sample heating allow researchers to get even more data out of more samples and more conditions.

The unique combination of an accessible, versatile SEM with advanced features makes Quattro the central player in today’s materials science labs.

2017 Nobel Prize in Chemistry

Congratulations to the winners of the 2017 Nobel Prize in Chemistry. Three scientists; Dr. Jacques Dubochet, Dr. Joachim Frank, and Dr. Richard Henderson, were awarded the prize for their developments within Cryo-Electron Microscopy.

We are extremely proud of what these researchers and the structural biology community have achieved.
