HITACHI S-4700 is a scanning electron microscope (SEM) that is used for high resolution and large field of view imaging and analysis. It is one of the most powerful tools in the field of microscopic analysis and is capable of operating at a high voltage of up to 80 kV. This makes the system ideal for imaging and analyzing various types of samples ranging from biological cells and insects to minerals and other materials. HITACHI S 4700 system offers a number of features that make it an ideal choice for many labs. Besides its highly sensitive and reliable imaging capabilities, it has an intuitive user interface and integrated imaging software that features hard and soft automation features. This enables sample preparation, scanning and analysis operations to be streamlined and efficient. Moreover, it has the latest vacuum technology, offering excellent vacuum pressure stability and ultra-low background noise levels. The maximum achievable resolution of S-4700 is around 0.7nm, which means it can easily resolve sub-micron features. This makes it ideal for imaging fine structures and particles that cannot be seen on an optical microscope. It also provides a wide range of analytical capabilities including elemental analysis and energy dispersive spectroscopy (EDS). This enables users to perform depth profiling and X-ray microanalysis to get detailed information on the elemental composition of their sample. Furthermore, its high quality variable pressure chamber allows users to operate the system at pressures ranging from 0.05mbar to 5 mbar, which means it can be used for observing specimens that are sensitive to the environment. S 4700 is packed with a host of other features and options that make it a highly attractive choice for any laboratory. It is capable of digital capturing and incorporates features such as spot size correction, background suppression and automatic focus, making it even easier to make high quality images for analysis. In addition, its advanced multi-scan modes allow for simultaneous imaging in two different regions of the sample, greatly increasing the speed and efficiency of imaging. In conclusion, HITACHI S-4700 is an invaluable tool for any lab looking to perform high resolution imaging and analysis and is a highly reliable and powerful machine.
