Used JEOL JSM 6401 #9073237 for sale

JEOL JSM 6401 is a scanning electron microscope (SEM) that utilizes an electron beam to create images of a sample surface at a high magnification. It has a high resolution of 1.3 nm, enabling researchers to observe atomic-scale samples with precision. The SEM can also be used to non-invasively analyze samples, as the electron beam does not affect the samples in any way. JSM 6401 includes a powerful field emission gun (FEG) that focuses and directs the electron beam with a high degree of accuracy. This gun has an accelerating voltage of up to 30 kV and is cooled with liquid nitrogen. This ensures that the beam remains sharp and uniform, resulting in high-quality images. The microscope also includes a liquid nitrogen cooling system to protect the electron optics and samples from thermal damage. JEOL JSM 6401 provides a variety of imaging modes that allow researchers to observe the sample surface in various ways. The most notable are scanning mode, which is used to capture general images of a sample's topography, and backscatter electron imaging (BSD) mode, which is used to analyze samples composition. Other modes, such as energy dispersive x-ray (EDX) mode, electron backscatter diffraction (EBSD) mode, and high-resolution imaging mode, are also available to enable researchers to have greater insight into the samples under investigation. In addition to its imaging capabilities, JSM 6401 also includes an automated sample holder that quickly loads multiple samples into the SEM. This holder is equipped with a goniometer, which allows for optimal sample positioning and avoids the need for manual sample adjustment. Furthermore, the system includes a digital image processor that processes the acquired images and can adjust the brightness and contrast. JEOL JSM 6401 is a reliable scanning electron microscope that provides powerful imaging and analysis capabilities for researchers. Its high resolution and a variety of imaging modes allow for the examination of samples at an atomic level, while its automated sample holder and digital image processor simplify the tasks of loading and processing the acquired images. Together, these features make JSM 6401 an invaluable tool in the lab.
