Used GATAN 681 #293677376 for sale

GATAN 681 is a cutting-edge ion milling equipment designed for precise and high-quality thinning of samples for transmission electron microscopy (TEM) and other advanced imaging techniques. This sophisticated instrument is manufactured by GATAN, a leading provider of solutions for electron microcopy applications. At the core of 681 system is the ion source, which generates a focused beam of ions that can be precisely directed onto the sample surface. The ion source typically utilizes gallium ions due to their high sputtering efficiency and controllability. This beam of ions bombards the sample surface, sputtering away material and gradually thinning the specimen to the desired thickness. One of the key features of GATAN 681 ion milling unit is its high precision and control over the thinning process. Users can adjust parameters such as ion beam energy, beam current, and milling angle to tailor the milling process to the specific requirements of their samples. This level of control allows researchers to achieve ultra-thin specimens with minimal damage and distortion, crucial for obtaining high-quality TEM images and accurate structural analysis. 681 is equipped with advanced imaging and monitoring capabilities to facilitate real-time observation of the thinning process. The machine typically includes integrated cameras and microscopes that allow users to visually inspect the sample during milling. This feedback loop enables users to make informed adjustments to the milling parameters in order to achieve the desired thinning results. In addition to its thinning capabilities, GATAN 681 ion milling tool can also be used for surface cleaning and preparation of samples for analytical techniques such as energy dispersive X-ray spectroscopy (EDS) or electron backscatter diffraction (EBSD). By removing surface contamination and artefacts, the asset ensures that samples are optimized for accurate and reliable analysis. 681 ion milling model is equipped with safety features to protect both the user and the instrument. These may include vacuum interlocks to prevent accidental exposure to the ion beam, integrated shielding to contain ion emissions, and emergency stop mechanisms to halt the milling process in case of a malfunction. Overall, GATAN 681 ion milling equipment represents a state-of-the-art solution for precise and controlled thinning of samples for electron microscopy applications. Its advanced features, high precision, and real-time monitoring capabilities make it an indispensable tool for researchers and scientists seeking to obtain high-quality images and accurate structural information from their specimens.
