Used JEOL JSM 840A #293592718 for sale

JEOL JSM 840A is a scanning electron microscope ("SEM") designed for a wide range of applications in science and industry. The SEM is capable of producing high resolution images of nano-scale objects, ranging from micrometers to nanometers, with an energy dispersive X-ray spectroscopy (EDS) system. The instrument is optimized for imaging, analysis and other scientific purposes, such as visualization of structures in biological materials, as well as materials characterization and elemental analysis of both low and high-Z materials. JEOL JSM-840A has a LAN interface and is equipped with a dedicated fast image process, allowing for up to one megapixel resolution. It has a magnification of up to one million times, over 64x at original scan size, allowing for high resolution imaging of densely packed fine structures. The EDS system is capable of direct analysis of both low and high-Z materials, with a broad range from the visible to the X-ray wavelengths. The SEM is equipped with a unique 'whisperer' lens, which maintains a stable path between the objective lens and the specimen, thus providing a high contrast image with no aberrations. JSM 840A is equipped with a variable pressure system, allowing for operation under different atmospheric conditions, as well as imaging in vacuum. It is also equipped with a parametrol lens, which allows the user to independently control both voltage and current, to further optimize the image contrast. JSM-840A is designed to be intuitive and user-friendly, offering powerful software, including a user-friendly graphical user interface (GUI), which simplifies operation and control of the instrument. The SEM is also equipped with many safety and security features, including security locks and vibration-proof systems, ensuring a safe working environment for both the user and the instrument. Overall, JEOL JSM 840A is a powerful, user-friendly scanning electron microscope, ideal for both characterization and imaging of nano-scale objects. It can produce high resolution images with excellent contrast, and is equipped with a variety of features to simplify operation and improve safety.
