Used GATAN 691 #293766320 for sale

GATAN 691 is a semiconductor ion milling system. It is part of the Ion Mill product line from GATAN, a company specialized in materials analysis and sample preparation equipment. 691 is designed to quickly and accurately mill the surfaces of specimens with a minimal amount of material loss. It is capable of milling a range of samples, from extremely hard materials such as dental implants and electronic components, to extremely soft materials like biological specimens. GATAN 691 system uses ion milling technology to mill specimen surfaces. Instead of using a mechanical tool to cut the specimen, the ion mill works by bombarding the sample with a beam of ionized gas, such as argon or oxygen, at high energy. This beam of ions interacts with the surface atoms of the sample, slowly wearing it away one layer at a time. By controlling the machine parameters such as gas pressure, beam current and target angle, it is possible to precisely control the depth and roughness of the milled surface. 691 system offers several features that set it apart from other ion milling systems. For example, it is equipped with a scintillation detector that allows the user to observe the progress of the milling process in real time. This ensures that the optimal amount of material is removed and the sample is not over-milled. GATAN 691 also has built-in safeguards to prevent any damage to the specimen. It is designed to be able to shut itself off automatically in the event that the specimen surface becomes too hot during the milling process. 691 is a cost-effective and accurate solution for a variety of specimen preparation needs. It provides an ideal way to prepare a surface for microscopy, electron imaging, or other specimen analysis techniques. By controlling the milling parameters, it is possible to obtain a precisely defined surface for visual inspection or further study. With its ergonomic design, intuitive controls, and built-in safeguards, GATAN 691 is an excellent choice for any laboratory engaged in surface preparation of specimens.
