Used JEOL 6400 #293820899 for sale

JEOL 6400 is a scanning electron microscope (SEM) that is widely used for materials characterization and imaging. It provides high-resolution imaging and chemical analysis of various material types including metals, ceramics, minerals and semiconductors. 6400 features a low-voltage field emission gun and a cryo stage that allows observations of specimens in their native environment. The field emission gun (FEG) of JEOL 6400 produces extremely high electron beams in order to acquire detailed images and to analyze specimens both chemically and physically. The FEG delivers a high energy beam formed by a special electron source. This electron source consists of a tungsten needle with a special tip that is held at a low temperature and voltage. By varying the voltage, the beam intensity can be adjusted by the microscope operator. With this technology, 6400 achieves the highest resolution of 1.2 nm for compositional and topographical image contrast. JEOL 6400 is designed for cryogenic applications and comes with a cryo stage. This stage can be cooled to as low as -120 °C so that the specimen can be observed at temperatures close to its native environment. The cryo stage allows for specimens to be investigated without being damaged by the heat of the electron beam, resulting in improved contrast and resolution. 6400 is also equipped with automated features such as the 'Auto Scan' feature that allows for automated scan control, and the 'Auto Retract' feature that automatically retracts the electron gun when a shift in the specimen is detected. It also has an 'Auto Count' feature that enables the user to count particles and features on the specimen. Additionally, JEOL 6400 comes with an automated alignment procedure to simplify the focusing process. 6400 is a powerful scanning electron microscope that provides high-resolution images of various materials with a wide range of applications. With its automated features and cryo stage, it is a reliable and efficient tool for scientific research and quality assurance.
