Used GATAN 691 #293637741 for sale

GATAN 691 ion milling equipment is a high-grade instrument designed to finish, clean, and stabilize surfaces with extreme precision. It is used in electron microscopy, specimen preparation, thin-film technology, and other areas of materials science. The instrument is equipped with a high-performance electrical source with adjustable current levels, automatically-controlled voltage burst levels, and frequency tuning. This allows the operator to modify the milling rate when needed, producing a uniform finish on the subject's surface. It also guarantees a repeatable, homogeneous idling operation. The machine also has a built-in gas feed system. This enables precise control over the ion energy and milling rate, leading to extremely accurate results. As well, the Ne-1-Ar gas mixture allows rapid dissolution of oxides and material restructuring without creating any heat-related damage. The four-axis movement framework allows the user to modify the ion beam's orientation quickly and accurately. This makes it easier to create precise structures on the subject's surface. The machine's inert plasma is enclosed within a vacuum chamber which is temperature-controlled during operation. For added safety, the device can be kept in manual override and constantly monitored during operation to ensure safety standards are being observed. As well, the machine's sophisticated nanometer-scale imaging unit can track the positions of the ion beam and milling parts in real-time, providing the user with an unparalleled level of precision. Overall, 691 ion milling machine is an incredibly precise, reliable, and user-friendly instrument. It is capable of producing highly accurate shapes and structures, with excellent repeatability, on a variety of surfaces and materials. Its powerful gas feed and adjustable ion energies allow for maximum flexibility while milling, and its intense safety measures guarantee a safe operation even in industrial settings.
