Used JEOL JSM 840A #9210598 for sale

JEOL JSM 840A is a high-end scanning electron microscope with advanced imaging capabilities. Its scanning electron optics combine a wide range of detection modes including backscatter, secondary electrons, transmitted electrons, and energy-dispersive X-ray spectroscopy. It also features a high-resolution digital imaging equipment and sophisticated sample preparation techniques. JEOL JSM-840A offers a maximum electron gun current of 0.2-40 nA and a resolution down to 5 nm. Its impressive magnification range, from 50 to 400,000 times, allows detailed scanning and analysis of a wide range of samples. Its variable pressure (0.015-0.5 Pa) and high-speed scanning (up to 10,000 frames/s) systems facilitate observation of unstable and dynamic features such as corrosion, erosion, and other forms of damage. JSM 840A also features a fixed-wavelength X-ray detector and a tiltable specimen chamer, both of which enable analysis of a variety of materials spanning the entire periodic table. JSM-840A has a printed circuit board (PCB) etching chamber that can facilitate imaging of very small objects. An automated sample manager (ASM) system handles the presentation of samples without manual manipulation. For ultimate flexibility, its advanced computer-controlled sample positioning unit provides 3-axis tilt and rotation. Together, the SEM and ASM enable repeated scanning and imaging of the same sample without damage. The 840A's user-friendly, intuitive user interface, combined with its broad range of dedicated software packages, makes it easy to operate. It enables users to customize the magnification, acceleration voltage, beam current and tilt. Additional features such as beam blanking, frame averaging, contrast adjustment and particle size recognition also facilitate precise and delicate imaging operations. In conclusion, JEOL JSM 840A is a powerful, multi-purpose scanning electron microscope that is perfectly suited for investigating a wide range of materials. With its impressive optics, advanced digital imaging machine, sophisticated sample preparation techniques, and intuitive user interface, the 840A is an ideal tool for both trained professionals and novice researchers.
