Used HITACHI FB-2000A #293750060 for sale

HITACHI FB-2000A is a scanning electron microscope (SEM) designed for observation of both biological and non-biological materials at the nanoscale. It has a conventional column and digital imaging equipment and features an integrated design for precise images and high accuracy in the analysis of materials. The included analysis software helps automate complicated processes, making it easier to use for scientists and engineers alike. The primary components of the system are the electron gun, electron optical column, and digital imaging unit. The gun is used to generate the electron beam used to scan the specimen, the optical column focuses and steers the beam to the specimen, and the imaging machine collects the resulting secondary electrons for measurement.The gun is a Schottky type with field emission, meaning it is capable of generating low currents necessary for high resolution images. The optical column uses multipole magnetic lenses and electromagnetic field deflectors to navigate the beam over the sample. The digital imaging tool includes a charge-coupled device (CCD) camera and various electronics for signal processing. HITACHI FB 2000A has a variety of modes including a variable pressure (VP) detector, for analyzing non-conductive samples, and an energy dispersive X-ray spectrometer (EDS) for measuring elemental composition. Both of these modes can operate at high vacuum, but they can be switched to low vacuum too. This allows for examination of samples of larger scale than the beam spot size, since the imaging can be done with less scattering from air molecules due to the small vacuum prevailing in the chamber. FB-2000 A is also equipped with a a digital controller, which allows it to be operated by computer using a graphical user interface. This controller enables the automation of the scanning, analysis, and data collection processes. It also allows for remote control, data monitoring, and storage across multiple computing devices. In addition to the controller, HITACHI FB-2000 A includes a semi-automatic specimen holder that facilitates quick, precise, and safe transfer of samples to and from the SEM chamber. The specimen holder is made of nonmagnetic material and is compatible with routine microscopy techniques such as Galta, FPD, and CLSM. Overall, FB-2000A is an excellent choice for examining materials with an extended range that includes both biological and non-biological specimens. It is equipped with well-designed features that enable high accuracy and precise analysis, while the included automation software streamlines and simplifies operation. With these capabilities, FB 2000A is an exceptional instrument for tackling complicated nanoscale studies.
